Introduction

Benchtop grinders are, of course, benchtop tools that have abrasive wheels spinning at high speeds. This gives it a wide range of uses because it allows you to sharpen tools, remove rust and shape parts, just to name a few.

DeWalt’s DW758 is one such tool and it is equipped with quite a powerful motor that is suitable for heavy-duty, industrial use. There are more features that this grinder has to offer so let’s take a deep dive into its review below to get more info about it.

Performance: Suitable for Industrial Use

The most outstanding feature of DeWalt’s DW758 is its motor because it is very powerful. It is an efficient induction motor that produces up to 3/4 horsepower.

With this power, the motor spins at speeds of up to 3600 RPM, which is quick enough for high-speed material removal. This also gives you enough power for heavy-duty grinding on an industrial scale.

As a result, you can use the tool for all kinds of grinding applications, be it sharpening tools, deburring, shaping objects, cleaning, or rust removal.

Additionally, the unit has a wide 12.5-inch distance between the wheels, which allows for longer and larger tools to fit when grinding using either wheel.

That said, the two wheels include a 36-grit and a 60-grit wheel, each with an 8-inch diameter. The 36-grit side has a coarse surface that is ideal for heavy-duty grinding, cleaning, sharpening, and stripping.

On the other hand, the 60-grit wheel has a smoother surface that is better suited for smoothing and rubbing off small imperfections.  

Other than that, you get a precision-machined aluminum tool rest on each wheel that holds the tools you are grinding firmly in place. As a result, you can accurately position these pieces for precise, high-quality grinding.

 Design & Construction: Sturdy and Very Durable

DeWalt DW758 is built using rugged cast iron, which forms the base and the motor housing (frame). This gives it a solid structure that is guaranteed to handle rough handling with ease for long-lasting use.

The only problem is that cast iron is very heavy and as such, the tool weighs 39.5 lbs. This is a lot of weight for its size. On the bright side, this weight keeps it very steady on the bench, allowing you to use it for high precision grinding.

Ease of Use: Convenience at your Fingertips

The DW758 bench grinder is equipped with multiple features that make it very easy to use. For starters, it has a tool-free adjustable guard, which allows for quick guard installation and adjustments.

This guard protects you from the abrasive spinning wheel, while also directing sparks and debris away from your hand.

Adjustability is meant to ensure you keep the guard at the optimal position for maximum protection. Being tool-free, this will only take a few seconds to set to the most optimal position.

That said, these guards have exhaust ports at the rear side, which can be hooked up to shop vacs to suck out all the debris as you grind or sharpen your tools. As a result, you get a very smooth operation with no interruptions.

As stated above, there is a precision-machined aluminum tool rest for each wheel and this makes it easy to hold the tools you are sharpening, cleaning, grinding, etc. These are also adjustable for optimal positioning.

Other features include a large front switch that is easily accessible for powering the motor on/off and transparent eye shields that can be adjusted tool-free. All these features are very convenient. 

Safety Features: Overload Protection

There are two ways of looking at safety features in the DW758. First are the features that safeguard the grinder and the most notable one is overload protection. This feature automatically shuts off the motor in case it overheats.

Such a scenario occurs if you place a heavy load on the wheels, which will slow down the motor and cause it to overwork. As it is trying to catch up in speed, it overheats and the overload protection kicks in to prevent it from getting damaged.

By doing so, this feature maximizes the motor’s lifespan.

The second category consists of the features that safeguard you as the user. In this, there are the wheel guards and as stated above, these protect your hands from the spinning wheels, sparks, and debris.

There are also eye shields, which keep sparks and debris from reaching your eyes while giving you a clear view of the work area.

Price: Mid-Range

DeWalt’s DW758 is neither affordable nor expensive. It sits in the middle of the price range as compared to other similar products because it costs less than $200.

That said, within the manufacturer’s lineup of bench grinders, there is only one more option, which is the DeWalt DW756. This is a very affordable grinder because it costs less than $100. However, it is inferior to the DW758.

It has smaller 6-inch wheels, a less powerful 4-Amp, 5/8 HP induction motor that spins the wheels at 3450 RPM, and a larger 1/2-inch spindle diameter. On the bright side, it is lighter (28.5 lbs.) and is more compact.

Verdict

A powerful and durable industrial-grade bench grinder that is ideal for personal projects or commercial use. 

With a 4.2-Amp, 3/4 HP motor, DeWalt’s DW758 is powerful enough to be used for all kinds of grinding applications. This includes deburring, sharpening tools, and rust removal, just to name a few.

In addition to that, the unit is very durable. It owes this to a cast iron construction for structural strength and an overload protection feature that prevents the motor from burning out. Combined, these features make it ideal for personal or commercial use.
