1″ x 8tpi Screw Chuck

Manufactured from aircraft-grade aluminum, the Glaser Screw Chuck has the distinction of being the only American-made chuck of its kind.

At its center is a hardened medical-grade stainless steel screw mounted in the anodized aluminum body. The screw features a specially ground thin, non-tapered thread designed to penetrate wood cleanly while minimizing damage to the workpiece.

The Glaser Screw Chuck comes standard with a reversible 3½″ faceplate, which screws over the chuck body to provide additional support. Optional 4½″ and 5½″ faceplates are also available for mounting larger workpieces.

For facework or centerwork, simply drill a ¼″ hole in the stock and thread it onto the chuck. The screw grips tenaciously—even in end grain—something many other screws cannot achieve. Mounting and removing work is fast and reliable, which explains the popularity of the Glaser Screw Chuck among production turners.

Work removed from the lathe can be accurately remounted without loss of alignment. The Glaser Screw Chuck is also ideal for mounting jam chucks and other wooden faceplates.
