Techniks 05534 Rigid Tap Collet ER25 6 Mm

Product Description

The TECHNIKS 05534 is a rigid tap collet designed for use with ER25 collet chucks in CNC machining and manual tapping operations. The collet accepts a 6 mm shank size and a 4.90 mm square drive, making it compatible with M5, M6, and M8 hand taps. Unlike tension-compression tap collets, this rigid-style collet holds the tap at a fixed axial position, requiring the machine feed to match the thread pitch precisely. It is used by machinists and CNC operators who need direct, rigid tap holding in controlled-feed tapping cycles.

This collet is suited for hand tap applications in ER25 toolholders across CNC machining centers, knee mills, and drill presses equipped with ER25 compatible spindles. The rigid design is appropriate for rigid tapping cycles where the machine spindle synchronizes feed with rotation. Typical applications include tapping threaded holes in aluminum, steel, and similar materials at the M5 through M8 thread size range. Through-coolant is not supported in this collet.

Key Features

• ER25 collet series for use in standard ER25 chucks and toolholders
• 6.00 mm collet size accommodates M5, M6, and M8 hand tap shanks
• 4.90 mm square drive size provides positive tap engagement and prevents rotation
• Rigid tap style with no tension or compression float for synchronized rigid tapping cycles
• No through-coolant passages, keeping the design simple and compact

Compatibility

Designed for use in ER25 collet chucks and toolholders accepting the ER25 collet series. Compatible with M5, M6, and M8 hand taps with a 6.00 mm shank diameter and 4.90 mm square drive.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with ER25 tooling systems. Ensure the machine spindle is fully stopped and the toolholder is removed from the spindle before seating or removing the collet. Clean the collet taper and chuck bore before assembly to prevent runout. Torque the ER25 nut to the toolholder specification provided by the chuck manufacturer.
