Kwik-Way Valve Grinders

Kwik-Way valve grinders are precision valve refacing machines built for engine rebuilding shops that demand accuracy and uptime. The air-activated, self-aligning six-ball chuck and patented Centerline System deliver superior alignment by gripping the valve stem at the portion that operates in the guide — the only reference point that matters. No collet swapping, no warm-up drift, no chatter. Manufactured in the United States since the early 1920s with an industry-best three-year warranty.

Kwik-Way valve grinders have been manufactured in the United States since the early 1920s. Built to last a career, every machine carries an industry-best three-year warranty and uses the patented Centerline System — gripping the valve stem at the portion that operates in the guide for alignment accuracy that collet and conical-centering designs can’t match. Two models are available: choose based on your chuck precision requirement and the range of valve stems you work with.
