Precision Machine 3-in-1 Screw Chuck

Precision Machine screw chucks have long been a staple item in our woodturning workshop because of their versatility and ease of operation. Whether you're roughing bowls, turning boxes or making wooden jigs and jam chucks, the Precision Machine 3-in-1 is perfectly suited for the task. To use, simply drill a hole in the blank to be mounted, thread the blank onto the screw until it rests against the face of the chuck and you’re off and running. When needed, you can remove or remount blanks and the work will re-center again. And with two different sizes of woodworm screws (1/4" and 3/8" dia. included) and reversible tapered collar, you have what you need for most types of work. The Precision Machine 3-in-1 Screw Chuck includes: a machined steel chuck body with 1-1/2" diameter face, 1/4" and 3/8" diameter interchangeable hardened stainless steel woodworm screws, a 1"-8 TPI spindle adapter, and an aluminum reversible collar that gives you a 2-1/2" and 3-1/2" face for holding larger work. The optional Jumbo Reversible Collar provides a 4-1/2" and 6-1/2" face that's ideal when chucking large bowls and platters.
