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.
Chuck not included.
