Bench Grinder Reviews

#1 – DeWalt DW758 8-Inch Bench Grinder

The DeWalt DW758 is manufactured with the same durability as other DeWalt tools, which is why it ranks among the best. It’s been a top seller for years and considered by many to be the best 8-inch bench grinder for the money.

The 3/4 horsepower induction motor effortlessly rotates the grinding wheels at 3,600 RPM (no load). The 12-1/2-inch distance between wheels provides excellent access for larger workpieces. Sharpening lawn mower blades or shovels is going to be a piece of cake on this model compared to many other models.

The 5/8-inch arbor (shaft) is well balanced and the cast iron base is nice and heavy (the grinder weighs 40 lbs) so don’t expect to have any wobble issues like other grinders in this price range. You’ll also notice it’s fairly quiet so if you previously had to put up with an entry level grinder, you’ll hear the difference right away.

DeWalt includes quality 36 and 60-grit wheels right out of the box, along with eye shields and spark deflectors. The grinder comes with DeWalt’s reliable 3-year limited warranty plus their 1-year free service contract for peace of mind.

It’s worth mentioning that the 6-inch version (DW756) is also quite good, so if space is a bit limited or your budget won’t allow the larger model, there’s another great option at a slightly lower price.

With any tool, it is a good idea to verify the factory installation before using, to be sure that all nuts are securely in place. A few users have reported they had to remove and remount the wheels, which were not installed well at the factory. Fortunately, the process is pretty straightforward.

All in all, this DeWalt is considered by many to be the best 8-inch bench grinder for the money. If you need something a bit more heavy duty, consider the Jet or Metabo models below.

#2 – Jet IBG-8 8-Inch Industrial Bench Grinder

With a full 1 horsepower single phase motor, this Jet bench grinder makes quick work of almost any job. The two 8-inch vitrified wheels are an industrial 36-grain and 60-grain coarseness for improved versatility and spin smoothly at 3,600 RPM.

Safety features include easy-adjusting spark guards and eye shields, cast iron wheel guards with dust collector ports, and heavy-duty toggle switch w/ safety key. A rubber foot adds stability without preventing you from bolting the grinder to a surface.

When you want a fast, powerful, and quiet grinder, the IBG-8 is an excellent choice. It quickly comes up to speed and quiets down to a hum as it runs. With a full horsepower, it’s also not going to bog down like cheaper units.

Professional users repeatedly place it near the top of their list when discussing grinders (often right behind the more expensive Baldor models), noting how smooth and quiet it is.

At 44 pounds, vibration should be almost non-existent but a few users have reported their grinder was producing excessive vibration, even when bolted down. This is almost always the result of a wheel that has become unbalanced and can happen to any grinder.

If you only have need for a bench grinder once a month, the less expensive DeWalt or even WEN model might be the wise choice. But if your job (or hobby) requires daily use, the Jet fits the bill.

#3 – Baldor-Reliance 712 7-Inch Bench Grinder

Baldor is a name synonymous with bench grinders. Made in the USA, Baldor represents the absolute best in bench grinder quality. It falls in the “buy it for life” tier that most people simply won’t have the budget for. But for an industrial setting, it may be well worth the investment. A “buy once, cry once” type of purchase. 

This 7-inch professional grinder features a 3.4-Amp, 1/2 HP induction motor that delivers 3,600 RPM for consistent, reliable performance that will outlast cheaper alternatives by (literally) decades. Though stated as 1/2 HP, it feels more powerful than that. 

What sets the Baldor apart is its 45 pounds of industrial-grade construction with sealed and lubricated ball bearings, a cast iron base, precision-machined components that virtually eliminate vibration, and even cast-iron wheel guards.

The 5/8-inch arbor accommodates standard wheels, while the 16-1/4 inch distance between wheels provides ample workspace for larger projects. We like the base-mounted on/off switch and stamped steel tool rests that make operation both safe and precise.

While the Baldor commands a premium price, it delivers professional-level performance that justifies the investment for serious metalworkers and craftsmen. The grinder includes 36 and 60-grit wheels and comes with the backing of Baldor’s reputation for manufacturing some of the finest industrial equipment available.

If you’re tired of replacing cheap grinders every few years and want something that will serve you for a lifetime, the Baldor 712 is worth every penny. If it’s out of your budget, you may be able to find a used Baldor on your local Facebook Marketplace or Craigslist, but they tend to go really quick.

#4 – Hercules (Harbor Freight) 8-Inch Professional Bench Grinder

While Harbor Freight’s Bauer line of bench grinders are a popular economy purchase, their Hercules brand grinder is what we actually recommend. The HE093 8-inch bench grinder is a real powerhouse. With a 1 HP induction motor that reaches 3,450 RPM, this grinder delivers professional-level performance at a fraction of the cost of comparable units from legacy brands.

Its quick-start motor with capacitor reaches full speed in less than 2.5 seconds (faster than most grinders in this class). The motor stall force of 50+ pounds means it won’t bog down under heavy loads, while sealed and lubricated ball bearings provide long-lasting performance.

We like the balanced clamp washers that minimize vibration and the dual cast-iron work rests with tool-free adjustment. Safety features include two extra-wide adjustable eye shields for better spark protection and a guarded toggle switch with safety key.

The cast-iron base contributes to its 49 pound weight, providing excellent stability during operation. While Harbor Freight’s reputation a short warranty period may give some pause, the HERCULES line represents a genuine step up in quality that competes directly with established brands.

At around half the price (or less) of comparable 1hp models, it offers exceptional value for both serious DIYers and professionals who need reliable performance without breaking the budget.

#5 – Bucktool TDS-200DS 8-Inch Dual Speed Bench Grinder

Not sure if you need a high-speed or low-speed grinder? This is the answer. This 8-inch dual speed grinder features a 1/2 hp motor that switches between 1,725 RPM and 3,450 RPM with the simple flip of a switch, giving you the versatility to handle both precision sharpening and heavy material removal.

We like the machined powder metal flange that greatly improves wheel balance and reduces vibration (a feature usually found on much more expensive grinders). The cast iron base with anti-vibration rubber feet keeps the unit stable during operation, while the position and angle adjustable eye shield with 3x magnifier helps achieve precision results that would be difficult with standard shields.

The grinder includes 80 grit and 120 grit grinding wheels made of white aluminum oxide that helps reduce heat build up. As a bonus, a buffing wheel for polishing is also in the box, making it a complete grinding and finishing station.

The dual speed capability is particularly valuable. You can use the lower speed for sharpening chisels and turning tools where heat control is important, and switch to high speed for rapid material removal and rust cleanup. At this price point, the Bucktool grinder offers features typically found on models costing twice as much.

Some users do say that the grinder is a bit underpowered for heavy duty tasks or when used for long periods so make sure you think about common use cases you’ll have for your bench grinder.

#6 – WEN BG625V 6-Inch Variable Speed Bench Grinder

The WEN BG625V takes the proven formula of WEN’s popular fixed-speed grinders and adds variable speed control from 2,000 to 3,400 RPM, making it an excellent choice for those who want more control over their grinding operations.

The 2.5-amp motor provides smooth, quiet operation while the 6-inch by 3/4-inch wheels (80-grit and 36-grit) handle light workshop tasks with ease. If you’re a DIYer or woodworker, this model is definitely worth a look. 

We appreciate the flexible work light that illuminates your workspace (a simple feature that makes a huge difference in grinding accuracy). The adjustable work rests pivot for angled grinding applications, and the simple speed adjustment knob lets you dial in the perfect speed for your specific task.

Lower speeds are ideal for sharpening delicate ools without overheating, while higher speeds make quick work of rust removal and heavy material removal. It’s not going to be the most powerful grinder, so expect it to bog down a bit if you apply decent pressure on a wheel. WEN doesn’t list a horsepower figure but if we were to guess, its 2.5-Amp motor would equal about 1/3 hp.

The build quality is typical WEN. Solid construction at a reasonable price point. The heavy-duty base with rubber feet provides good stability, and the guards remove easily for wheel changes. While it may not have the power or refinement of more expensive grinders, the BG625V offers variable speed capability that typically costs much more from other manufacturers.

#7 – WEN BG4276 6-Inch Bench Grinder

Beginning with its 1/3 HP (2.1 Amp) motor and 3450 RPM wheel speed, this 6 inch grinder is one of the most popular bench grinders for light duty use in your workshop or garage. The low price probably has something to do with that as well but it’s actually pretty well made compared to some other cheap bench grinders out there. WEN seems to excel at this across their tool line.

A flexible work light makes it easy to monitor progress, while the included 60-grit and 36-grit wheels give a wide range of grinding options. The heavy duty base ensures steadier operation and safer mounting.

This grinder does a good job buffing and polishing large pieces of metal. The rubber feet keep it steady and eliminate vibration. The machine can sharpen most of your tools with little effort (as long as you don’t apply too much pressure). And in the rare event there’s a problem, WEN’s customer service is top-notch.

Despite having a good overall speed, this grinder does have a slow startup and too much pressure on the wheels will start to overwhelm the motor and bog down the unit. Also, the light only works while the grinder is running, which has also frustrated some users.

While you probably won’t find a better grinder at this price point, unless you only plan on infrequent, light-duty tasks, it’s worth it to spend a bit extra on a more powerful unit.

Bench Grinder Buying Guide

Wheel Size

For most users, 8-inch wheels are the sweet spot. They offer more grinding surface to save time, last longer, and handle larger workpieces better than 6-inch models. The larger diameter also means less curvature on your tools’ cutting edges. However, 8-inch grinders do cost more and take up additional bench space.

6-inch grinders work well for light-duty tasks and smaller workshops. They’re cheaper and more compact, but the housing often extends past the wheels, limiting access when working on longer pieces like lawnmower blades and full size gardening tools.

Some premium brands like Baldor offer 7-inch wheels as a middle ground; more capacity than 6-inch with better workspace access than their larger counterparts, though wheel selection can be more limited.

Choose 6-inch if budget and space are tight, but go with 8-inch (or 7-inch for premium models) if you can swing it for better performance and versatility.

Motor Power

Motor power is measured in horsepower (HP) and amperage.

• For light home use, 1/3 HP (around 2-3 amps) handles basic sharpening tasks.
• Most serious DIYers should look for 1/2 to 3/4 HP (3-5 amps) for reliable performance and the ability to handle heavier work without bogging down.
• Professional or heavy-duty use calls for 1 HP or more.

Don’t get too caught up in peak HP ratings; focus more on amp draw, which better indicate real-world performance.

Speed

Low Speed (1,750 RPM)

Low-speed grinders run cooler and are ideal for sharpening woodworking tools like chisels and plane irons. The slower speed prevents overheating that can ruin a tool’s temper. They’re perfect for precision work but remove material more slowly.

High Speed (3,400+ RPM)

Recommended for the majority of users, high-speed grinders excel at rapid material removal, rust cleanup, and general grinding tasks. They work faster but generate more heat, which can damage delicate cutting edges if you’re not careful. Most bench grinders fall into this category.

Variable Speed

Variable speed grinders offer the best of both worlds. They offer low speeds for precision sharpening and high speeds for heavy grinding. They cost more but provide maximum versatility. Dual-speed models with preset low and high settings are more affordable than infinitely variable units (like where you turn a knob).

Arbor Size and Compatibility

Most grinders use a 1/2-inch or 5/8-inch arbor (the shaft that holds the wheels), regardless of where they’re manufactured. This includes virtually all Chinese and Taiwanese-made grinders, which follow American standards to ensure compatibility with widely available, affordable wheels.

Some European brands like Metabo use larger arbors (1-inch or 1-1/4-inch), which require specific wheels that cost more and have limited availability. Check arbor size before buying, especially if you plan to use specialty wheels like CBN or diamond.

Space and Mounting

Bench grinders need solid mounting to perform well and operate safely. Plan for the grinder’s footprint plus clearance for longer workpieces. Most grinders weighing 40+ pounds work fine sitting on top of a heavy workbench, but bolting them down is recommended. Lighter grinders should always be bolted down for safety.

Consider a dedicated grinder stand if your bench isn’t suitable. Stands provide rock-solid mounting and often include tool storage and water pots for quenching. Allow at least 12 inches of clearance on both sides for longer tools, and ensure adequate lighting and ventilation in your chosen location.

FAQs

What is a Bench Grinder Used For?

Besides grinding (as the name implies), bench grinders are among the most versatile tools in any workshop. They excel at bringing dull, damaged, or rusty tools back to life, saving you money and keeping your projects moving forward.

Sharpening and Honing

Bench grinders are unmatched for sharpening everything from lawn mower blades and axes to chisels, plane irons, and drill bits. Match wheel grit to your task. This means coarse wheels (36-60 grit) for major reshaping and fine wheels (100-120 grit) for final sharpening.

Cleaning and Restoration

Swap in a wire wheel and your grinder becomes a powerful cleaning station. Wire wheels are fantastic for removing rust, paint, and corrosion from metal parts, brackets, and hardware. They’re perfect for cleaning up old tools or restoring garden implements.

Shaping and Fabrication

Need to round over a sharp corner, clean up a rough weld, or modify hardware? Bench grinders make quick work of shaping metal and smoothing rough edges. With a buffing wheel and polishing compound, you can even achieve mirror finishes on metal projects.

Bench Grinder vs Belt Sander

Bench grinders are designed primarily for sharpening and polishing. They use two wheels that can be changed out to serve different tasks.

For instance, you can swap out a solid wheel for a metal brush wheel to remove rust for tools. They’re generally restricted to metal and remain affixed to a surface.

Belt sanders have two drums onto which a sanding belt is stretched. They can be used on softer materials, such as plastic. The speed of these machines is enough to easily damage material when not used carefully. Using one to sharpen tools can cause it to quickly overheat.

Bench Grinder vs Angle Grinder

Angle grinders are a lightweight sibling to bench grinders. While not as powerful, they’re highly portable and the ability to hold one makes it more precise. Because of their versatility, there are probably over 100 different uses for angle grinders.

Another key difference is the single wheel. You will need to swap wheels more often on an angle grinder, although the design means you can more easily cut and shape metal or remove paint from larger surfaces.
