Comprehensive review of DEWALT DW758 8-Inch Bench Grinder for power and precision

Description

Rugged Build and Durable Design

The DEWALT DW758 8-Inch Bench Grinder instantly stood out to me with its rugged cast iron base and motor housing. As someone who values durability in tools, I was impressed by how solidly this grinder is built. It feels incredibly sturdy, and there’s no worrying about wobbling or instability while in use. The 17.75″ x 12.63″ x 11.73″ dimensions give it a compact yet robust profile, making it ideal even for smaller workspaces. The yellow, black, and gray finish not only looks professional but feels like it can withstand years of wear and tear.

Setting it up was straightforward, but I did notice it’s heavier than expected at 39.5 pounds. While moving it around isn’t the easiest task, the weight also contributes to its stability during operation. For anyone who’s dealt with lightweight grinders that tend to slide around, this is a huge plus.

Performance and Power

What really sold me on this grinder is its 3/4 HP induction motor running at a blistering 3,600 RPM. The sheer power behind it makes quick work of rust removal, tool sharpening, and shaping metal. I used it to clean up some old tools that have been rusting away in my garage, and the results were fantastic. The grinder didn’t bog down or overheat, even when I applied a decent amount of pressure.

The 12-1/2-inch distance between the wheels is a game-changer, especially for larger grinding applications. It gave me enough room to work on longer pieces without feeling cramped. The included 36- and 60-grit wheels are great for both coarse and fine grinding tasks. Switching between them was seamless, and the rear exhaust ports in the wheel guards ensured smooth, dust-free operation.

Precision and Adjustability

One of the standout features is the precision-machined aluminum tool rests. These allow for accurate positioning of the workpiece, which is crucial for achieving clean and consistent results. I tested it on a couple of chisels, and the sharp edges were restored perfectly. Having these adjustable rests made me feel like I had more control over the grinding process, which is especially useful for intricate tasks.

Another detail I appreciated was the inclusion of eye shields and spark deflectors. While they’re not a substitute for proper safety goggles, they’re a nice layer of protection. The shields are clear and don’t obstruct visibility, which is a big win for me.

Key Benefits

• Powerful 3/4 HP motor capable of handling heavy-duty tasks with ease.
• Durable cast iron construction ensures longevity and stability.
• 12-1/2-inch distance between wheels accommodates larger projects.
• Adjustable tool rests allow for precision work.
• Comes with 36- and 60-grit wheels, covering a variety of grinding needs.

Areas of Concern

• Weight: At nearly 40 pounds, it isn’t the easiest tool to move around. If you’re planning to relocate it often, you’ll need to factor this in.
• Noise Level: While it’s not unbearably loud, the motor produces a noticeable hum when running at full speed. It’s manageable, but ear protection might be a good idea.
• No Variable Speed: Unlike some competitors, this grinder operates at a fixed speed of 3,600 RPM. While it’s perfect for high-speed material removal, a variable speed option would’ve made it even more versatile.

Competing Products

There’s no shortage of bench grinders on the market, but the DW758 holds its own against some tough competition. For instance, the WEN 4280 offers a variable speed option, which is great for more delicate tasks. However, it doesn’t pack the same power as the DEWALT DW758 and might struggle with heavier applications.

Another alternative is the JET 577102 JBG-8A, which shares a similar price range but weighs significantly more. While the JET grinder boasts industrial-grade performance, it lacks the rear exhaust ports that make the DEWALT model smoother and more efficient during prolonged use. The DEWALT also edges out competitors in terms of ease of setup and overall durability.

Price Performance

In terms of price performance, this bench grinder is hard to beat. While it’s not the cheapest option out there, the combination of power, durability, and precision makes it a worthwhile investment. Cheaper grinders often compromise on build quality or motor efficiency, but this one feels like it will last for years without giving up on performance. For anyone who frequently works on metalworking or tool restoration, this grinder delivers excellent value.

Ultimately, the DEWALT DW758 is a reliable and powerful tool that’s well-suited for both DIY enthusiasts and professionals alike. It’s not perfect, but the pros far outweigh the cons, making it a solid addition to any workshop.
