Oneway Chuck Spurs are available to mount directly into Chucks made by Oneway.At 3-3/4" diameter it easily drives pieces up to 24" in diameter but is safely contained inside the body diameter of even our smallest chuck. The spur has a 1" locating plug to center securely into the chuck and it is grabbed crosswise by the jaws for a secure hold. The teeth and point are 60 degrees so it will bite deeply and easlily. It takes advantage of the holding power of the chuck, making it very economical.
