#1. DEWALT Bench Grinder, 8-Inch (DW758). 

If you’re in search of a sharpener, the DeWalt DW758 is a standout choice. Powered by a robust 3/4 horsepower motor, it boasts a remarkable speed of 3600 RPM, making it the fastest on the market.

One notable feature is the emphasis on safety and ergonomics in the design. The wheel guards are equipped with exhaust ports at the back, enhancing the machine’s operational smoothness. Additionally, aluminum tool rests are strategically placed against the wheels, ensuring easy access to everything you need. 

Despite these advantages, a downside is the absence of a work light, which would have added to the unit’s convenience without a significant cost increase. While the DW758 is compact, it falls short on portability due to its substantial weight of 39.5 pounds. 

Nevertheless, it provides excellent value for your money, with sturdy and reliable operation. It can reach speeds of up to 3,450 RPM for high-speed requirements. The motor housing and base are constructed from industrial cast iron, contributing to the unit’s durability, while the aluminum tool rests maintain practicality.

The Rikon 80-805 presents itself as a grinder with a somewhat heavy-duty capability. Its ½ horsepower motor ensures a quick and smooth start-up, operating at a speed of up to 1750 rpm.
