Jet JC18C Die Grinder Collet 1/8 Inch JSM-522 JSM-532

Product Description

The JET JC18C is a 1/8 inch collet designed for use with JET die grinders. It secures 1/8 inch shank rotary accessories — such as carbide burrs, grinding stones, and mounted points — within the tool's spindle, transmitting torque cleanly during material removal operations. The collet is a precision-fit component; correct sizing is critical to safe, vibration-free operation. Machinists, fabricators, and tool-and-die technicians working with JET die grinders will find this a direct OEM-sourced replacement or spare when the original collet wears or is damaged.

Die grinder collets see regular wear in metalworking, welding prep, porting, deburring, and surface finishing applications. The JC18C fits JET models JSM-522 and JSM-532 and is suited to both bench and inline grinding tasks in shop environments. Keeping a spare collet on hand minimizes downtime when a worn collet causes runout or slippage during precision work.

Installation Notes

Collet replacement should be performed by a qualified technician familiar with pneumatic or electric die grinder service. Disconnect the air supply or unplug the tool before removing or installing any collet. Use the correct collet wrench and spindle-lock procedure as described in the tool's service documentation to avoid damaging the spindle threads. Do not overtighten; snug the collet nut securely to the manufacturer's standard practice without applying excessive force.
