Remember when you had maximum versatility with your wood lathe. Take on projects of all shapes and sizes with the WEN 3.75 in. 4-Jaw Self-Centering Keyed Scroll Chuck. This versatile chuck features dovetailed jaws, allowing you to grip the outside of stock between 1-1/4 to 2-1/2 in. in size, or to hold internal pilot holes ranging from 1-3/4 to 3-1/8 in. in diameter. The keyed tightening mechanism prevents the chuck from opening during high RPM operation, providing maximum clamping power to your workpiece.
