Techniks 05570-367 ER32 Tap Collet 0.367 in Hand Tap

Product Description

The TECHNIKS 05570-367 is an ER32 tap collet designed to securely hold 1/2 inch hand taps in ER32 collet chucks. With a collet size of 0.367 inches and a square drive size of 0.275 inches, this collet provides precise, rigid retention for hand tapping operations on machining centers and CNC mills. It is intended for use without tension-tap or through-coolant features, making it a straightforward, solid-grip solution for standard hand tap holders in production and job-shop environments. Machinists and toolroom technicians are the primary users of this type of collet.

This collet is suited for hand tapping applications in ferrous and non-ferrous materials where a rigid ER32 collet chuck is already in use. It accepts 1/2 inch hand taps and fits standard ER32 toolholding systems commonly found on vertical and horizontal machining centers. It is not configured for tension-compression tapping or coolant-through delivery, so it is best applied in operations where those features are not required.

Key Features

• ER32 collet series for broad compatibility with ER32 chuck bodies
• 0.367 inch bore size matched to 1/2 inch hand tap shank dimensions
• 0.275 inch square drive size for positive tap engagement
• Designed for hand tap style - not tension or pipe tap
• No through-coolant passages, simplifying setup in standard dry or flood-coolant environments
• Lightweight at 0.3 pounds for easy handling and quick collet changes

Compatibility

Designed for use with ER32 collet chucks and toolholders that accept the ER32 collet series, holding 1/2 inch hand taps with a 0.275 inch square drive.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before installing or removing the collet, ensure the machine spindle is fully stopped and the control is in a safe state. Seat the collet fully into the ER32 nut before threading onto the chuck body, and torque the nut using an appropriate ER collet wrench - do not use pipe wrenches or improvised tools. Verify that the tap shank seats squarely in the collet to prevent runout and tap breakage during the tapping cycle.
