Parlec ER32-0687 ER32 Collet 0.687 in Capacity

Product Description

The PARLEC ER32-0687 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle applications that accept ER32 toolholders. With a collet size of 0.687 inches and a minimum collet capacity of 0.648 inches, this collet provides a reliable clamping range for tool shanks within that span. The overall length is 1.574 inches. Machinists and tool crib technicians select ER collets for their consistent runout characteristics and broad compatibility across ER32-standard toolholding systems.

This collet is suited for production and job-shop environments running milling, drilling, reaming, or tapping operations. It fits any spindle or toolholder built to the ER32 collet standard. The 0.687-inch capacity accommodates a range of round tool shanks and workholding applications that fall within its specified clamping range. It is a single-piece collet intended for direct insertion into a compatible ER32 chuck or holder.

Installation Notes

ER collets are installed and removed by trained machinists or toolroom technicians using a proper ER32 collet nut and spanner wrench. Always ensure the spindle or toolholder is fully stopped and de-energized before changing collets. Do not exceed the collet clamping range when seating a tool shank, as under- or over-sizing the shank relative to the collet capacity can cause runout or tool pull-out. Follow the machine manufacturer and toolholder manufacturer torque guidelines for the collet nut.
