Techniks 05632 ER32 Rigid Tap Collet 20 Mm M27

Product Description

The TECHNIKS 05632 is an ER32 rigid tap collet designed to hold M27 hand taps in CNC machining centers and tapping machines. With a 20 mm collet bore and a 15 mm square drive, it securely grips the tap shank during threading operations, transmitting torque without slip. This collet does not feature through-coolant capability or tension-compression function, making it a straightforward, fixed-drive solution suited to shops that run rigid tapping cycles on machining centers or use dedicated tapping heads. Installation is handled by machinists and CNC setup technicians working with ER32-compatible toolholders.

The 05632 fits standard ER32 collet chucks and is intended for hand-tap style tooling in rigid tapping applications. The M27 tap size designation makes it appropriate for threading operations in medium-to-large diameter hole work, commonly encountered in industrial manufacturing, die and mold work, and general machine shop environments. The 15 mm square recess engages the tap shank securely to prevent rotation under load during the tapping cycle.

Key Features

• ER32 collet series for use with standard ER32 collet chucks
• 20 mm collet bore sized for M27 hand tap shanks
• 15 mm square drive recess for positive torque transmission
• Rigid (non-tension-compression) drive for machines with rigid tapping capability
• No through-coolant passages - simplified, low-maintenance design
• Lightweight at 0.5 pounds for reduced spindle load

Compatibility

Designed for use with ER32 collet chucks in rigid tapping applications; accepts M27 hand tap tooling with a 15 mm square shank drive.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing collets or tooling. Seat the collet fully into the ER32 collet chuck and tighten the retention nut to the toolholder manufacturer's specified procedure using an appropriate collet wrench. Confirm tap shank engagement with the square drive recess before running the tapping cycle.
