Techniks 05570-480 ER32 Tap Collet 0.48 Inch Hand Tap

Product Description

The TECHNIKS 05570-480 is an ER32 series tap collet designed to hold and drive hand taps in CNC machining centers and tapping attachments. It accepts a 5/8 inch hand tap with a 0.36 inch square drive and provides a collet bore size of 0.48 inches. The ER32 collet format gives a reliable, concentric grip on the tap shank, reducing the chance of tap breakage or misalignment during threading operations. This collet is a standard through-coolant-free, non-tension design, making it straightforward to set up in compatible ER32 toolholders. Machinists and CNC operators working in production or job-shop environments will find it a dependable fit for tapping steel, aluminum, and similar materials.

This collet is suited for use in ER32 collet chucks mounted on CNC mills, drill presses, and dedicated tapping machines. It is intended for hand tap applications only and does not support tension-compression tapping cycles. Typical use cases include threading through-holes and blind holes where a rigid or semi-rigid tapping setup is appropriate. The collet fits within any ER32-compatible toolholder that accepts standard DIN 6499 collets, giving it broad applicability across common machine tool setups in both production and maintenance machining environments.

Compatibility

Designed as an OEM-style replacement or standard tooling fit for ER32-compatible collet chucks used in CNC and manual tapping applications. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Before inserting or removing the collet, ensure the machine spindle is fully stopped and the tool is de-energized per standard lockout/tagout procedures. Seat the collet into the ER32 chuck bore before threading on the clamping nut, and torque the nut with an appropriate ER collet wrench to manufacturer specifications for the chuck. Inspect the collet bore and seating surface for chips or wear before each use to maintain concentricity and prevent premature tap breakage.
