Palmgren's family of Heavy-Duty Bench Grinders are designed and built with high-quality motors specifically for heavy duty and long duty work cycles. Every grinder provides four to seven times longer duty cycle under load and eight times less speed degradation than the competition. The grinders provide smooth, quiet power for grinding cleaning, deburring, chamfering and sharpening. Among the features are adjustable tool rests, and adjustable eye shields and spark guards. The grinders are available in wheel diameters ranging from 6-inches to 12.
