Techniks 04843 ER32 Collet Chuck Straight Shank

Product Description

The TECHNIKS 04843 is an ER32 collet chuck with a straight shank designed for use in CNC machining centers, milling machines, and drilling applications. It accepts ER32 collets with a clamping range from 1/16 inch up to 3/4 inch, covering a wide variety of tooling diameters in a single chuck body. The straight shank measures 1-1/4 inch in diameter with an overall length of 4.39 inches and a 60 mm projection. Machinists and CNC operators use this chuck as a reliable workholding and tool-holding solution in production and job-shop environments.

This ER32 collet chuck suits horizontal and vertical machining center setups where a straight-shank tool holder is required. It is appropriate for milling, drilling, reaming, and tapping operations in both ferrous and non-ferrous materials. The 60 mm projection provides clearance for typical workpiece geometries and fixturing arrangements. It is installed and serviced by CNC machinists and toolroom technicians in metalworking and manufacturing facilities.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle and any intermediate adapter are fully powered down and at a complete stop before mounting or removing the chuck. Clean the shank and spindle bore thoroughly before seating to ensure proper runout. Follow the machine tool manufacturer torque guidelines for the drawbar or clamping nut rather than applying arbitrary force.
