Parlec ER32-0125 ER32 Collet 0.125 Inch Bore

Product Description

The PARLEC ER32-0125 is an ER32 series collet with a 0.125 inch (1/8 inch) bore capacity, designed for use in ER32-compatible collet chucks on CNC machining centers, manual mills, and lathes. The collet measures 1.574 inches in overall length and accepts tooling down to a minimum capacity of 0.086 inches. Manufactured to ER32 standard geometry, it provides concentric, secure clamping of cutting tools, drill bits, taps, and round-shank tooling. Machinists and toolroom technicians rely on ER collets for their balance of holding force and quick tool changes in production and job-shop environments.

This collet is suited for light-to-medium material removal operations where a 1/8 inch shank tool is required. Typical applications include drilling, reaming, tapping, and end milling with small-diameter tooling. The ER32 series is one of the most widely used collet standards in CNC and manual machining, making this collet a common toolroom consumable across aerospace, automotive, and general metalworking shops.

Installation Notes

ER collets are installed and removed by a qualified machinist or toolroom technician using the appropriate ER32 collet nut and spanner wrench. Always ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Inspect the collet bore and chuck taper for chips or debris before seating the collet to avoid runout issues. Do not exceed the collet's stated clamping range to prevent damage to the collet or toolholder.
