Techniks 05330 ER16 Tap Collet 3.5 Mm Hand Tap

Product Description

The TECHNIKS 05330 is an ER16 tap collet designed to hold hand taps in CNC machining centers, tapping heads, and manual milling setups. Sized at 3.5 mm with a 2.70 mm square drive, this collet secures the tap shank and transmits torque without slippage during threading operations. It is compatible with M3 and M5 hand taps and fits any standard ER16 collet chuck. Machinists and toolroom technicians rely on this collet for accurate tap alignment and repeatable thread depth in production and maintenance environments. It does not support through-coolant delivery or tension-compression floating.

This collet is intended for hand tap applications in ER16 toolholding systems. Typical use cases include tapping aluminum, steel, and other metals in vertical machining centers or manual mills where a rigid tapping setup is preferred. The 3.5 mm bore accommodates M3 and M5 tap shanks directly. It is sold individually and suits both job shop and production floor use where quick collet changes between tap sizes are common.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Clean the collet, nut, and chuck taper before seating to prevent runout caused by chips or debris. Do not exceed the torque rating of the ER16 collet nut - consult the chuck manufacturer specifications for proper clamping torque.
