Accupro 588362 ER32 Collet 4 Mm

Product Description

The ACCUPRO 588362 is an ER32 series collet designed to hold 4 mm shank tooling in ER32-compatible tool holders and collet chucks. ER collets work by compressing radially when a clamping nut is tightened, securing cutting tools, drill bits, reamers, and other round-shank tooling for milling, drilling, and boring operations. This collet is rated to a clamping pressure of 1000 and ships as a single unit. It is a standard component used by machinists and CNC operators in shop and production environments.

This collet fits any ER32-standard collet chuck or tool holder, making it a common replacement or supplemental collet in CNC machining centers, manual milling machines, and drill presses equipped with ER32 tooling systems. The 4 mm bore size accommodates tooling with a 4 mm shank diameter. It is suited for light to medium material removal operations across a range of workpiece materials.

Installation Notes

ER collets are installed by a machinist or CNC technician. Before changing collets, ensure the machine spindle is fully stopped and all power is off or locked out per applicable lockout-tagout procedures. Seat the collet fully into the collet nut before threading onto the chuck body, and tighten to the chuck manufacturer's specified procedure using an appropriate ER spanner wrench. Do not overtighten or use impact tools on the collet nut.
