Techniks 05622 ER32 Tap Collet 15 Mm M20

Product Description

The TECHNIKS 05622 is an ER32 tap collet designed to secure hand taps in CNC machining centers, tapping heads, and compatible toolholding systems. Built to the ER32 collet standard, it accepts a 15 mm collet bore and is sized specifically for M20 hand taps with a 12 mm square drive. This collet provides consistent grip and concentricity during rigid or float tapping operations, making it a reliable choice for machinists and toolroom technicians working in production or job-shop environments.

This collet is intended for hand tap applications in standard ER32 collet chucks. The M20 tap sizing makes it appropriate for threading operations in medium-to-large bore work across general metalworking, fabrication, and manufacturing setups. It does not support through-coolant delivery and is not configured for tension-compression tapping - it is a rigid tap collet suited to hand tap use only.

Key Features

• ER32 collet series for broad compatibility with ER32-standard toolholders
• 15 mm collet bore sized for M20 hand taps
• 12 mm square drive engagement for positive tap retention
• Hand tap configuration - no tension-compression float
• No through-coolant passages, simplifying setup in standard chucks

Compatibility

Designed for use with ER32-standard collet chucks accepting 15 mm collets; matched to M20 hand taps with a 12 mm square.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with ER collet systems. Power down and de-energize the spindle before seating or removing the collet. Use a calibrated torque wrench and the appropriate ER32 spanner nut wrench to achieve proper clamping without over-torquing the nut. Verify tap square engagement before running the spindle.
