Techniks 05320-367 ER16 Tap Collet 0.367 Inch

Product Description

The TECHNIKS 05320-367 is an ER16 series tap collet designed to hold 1/2 inch hand taps in ER16-compatible toolholders. With a collet size of 0.367 inches and a square drive size of 0.275 inches, it provides a secure, positive drive for hand tapping operations on CNC machining centers and manual machines. This collet does not include through-coolant capability and is not configured for tension-compression tapping. It is installed by machinists and toolroom technicians in production and job-shop environments.

This collet is suited for standard hand tapping applications where a rigid, direct-drive setup is preferred. It fits ER16 collet chucks commonly used on vertical machining centers, drill presses, and tapping heads. Typical use cases include threading operations in ferrous and non-ferrous materials where a 1/2 inch tap is required and through-coolant delivery is not needed.

Key Features

• ER16 collet series for broad compatibility with ER16 toolholding systems
• 0.367 inch collet bore sized for 1/2 inch hand taps
• Square drive size of 0.275 inches provides positive tap engagement
• Rigid, non-tension configuration for direct-drive tapping

Compatibility

Designed for use with ER16-compatible collet chucks and toolholders accepting a 0.367 inch collet. Intended for 1/2 inch hand taps with a 0.275 inch square drive.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing collets. Seat the collet fully into the ER16 nut before threading onto the chuck body, and torque the collet nut to the toolholder manufacturer's specification using an ER collet wrench. Inspect the collet and chuck bore for chips or wear before each use.
