Techniks 05570-194 ER32 Tap Collet 0.194 in Hand Tap

Product Description

The TECHNIKS 05570-194 is an ER32 tap collet designed to hold hand taps in CNC machining centers, tapping heads, and manual machine tool spindles. With a collet size of 0.194 inches and a square drive size of 0.152 inches, this collet provides positive engagement on the tap shank for accurate, repeatable tapping operations. It is compatible with the standard ER32 collet chuck system, one of the most widely used toolholding interfaces in production and job-shop machining environments. Machinists and toolroom technicians install and use this collet as part of a rigid or floating tap holder assembly.

This collet is suited for hand tap sizes ranging from Number 10 to 3/16 inches in ferrous and non-ferrous workpieces. It is intended for use without through-coolant and does not support tension-compression (floating) tap holders - it is a rigid-style tap collet. Typical applications include tapping threaded holes in production runs or prototype work on vertical machining centers and drill-tap machines where ER32 toolholding is already in use.

Key Features

• ER32 collet series - fits standard ER32 collet chucks and nuts
• 0.194 inch collet bore accommodates Number 10 to 3/16 inch hand tap shanks
• 0.152 inch square drive engages the tap square for positive rotational drive
• Rigid tap collet design - no tension-compression float
• No through-coolant passages - suited for dry or flood-external coolant setups
• Lightweight at 0.5 pounds for minimal spindle load

Compatibility

Designed for use with ER32 collet chucks and compatible tap holders accepting the ER32 collet series. Fits hand taps in the Number 10 to 3/16 inch size range.

Installation Notes

Installation is performed by a machinist or toolroom technician familiar with ER32 toolholding systems. De-energize and lock out the machine spindle before changing collets or taps. Seat the collet fully into the ER32 nut before threading the nut onto the chuck body, and torque the collet nut with the appropriate ER32 spanner wrench to manufacturer specification. Inspect the tap shank and collet bore for chips or damage before each use to ensure proper seating and concentricity.
