Jet 650300 Wedge Type Tool Post Set

Product Description

The JET 650300 is a wedge type tool post set designed for use with JET 300 Series metal lathes. The tool post provides a rigid, repeatable clamping mechanism that holds cutting tools securely during turning operations. Wedge-style tool posts are preferred over piston-type designs because the wedge action draws the tool holder down and forward simultaneously, reducing chatter and improving surface finish. This set is installed and used by machinists, toolroom technicians, and metalworking professionals who require consistent tool height and angular repeatability across multiple setups.

The 650300 is intended for use with JET 300 Series lathes in shop, toolroom, and light industrial environments. It suits residential and small commercial machine shops where operators perform facing, turning, boring, and threading operations. The wedge type design allows quick tool holder swaps without losing centerline height, making it practical for production runs or job shop work where multiple tool profiles are needed in a single session.

Key Features

• Wedge-type clamping action for rigid, chatter-resistant tool holding
• Repeatable tool centerline height across holder changes
• Set configuration supports multiple cutting tool profiles
• Matched to JET 300 Series lathe specifications
• Weighs 7 pounds, indicating a solid, all-metal construction

Compatibility

Designed as a direct-fit tool post set for JET 300 Series metal lathes.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting the tool post, power down and lock out the lathe per applicable safety procedures. Secure the tool post to the compound rest using the center stud and nut to the appropriate snug fit — do not overtighten beyond hand-firm without confirming the compound rest thread specification. Verify cutting tool centerline height against the lathe spindle centerline before beginning any cutting operation.
