Techniks 19/11-4063 Tap Collet Ansi 1 0.255 Inch

Product Description

The TECHNIKS 19/11-4063 is an ANSI Series 1 tap collet designed to hold hand taps in compatible tap holders and tapping chucks. The collet features a bore size of 0.255 inches and a square drive size of 0.191 inches, matching the shank geometry of M6 and M6.3 taps. It is a precision workholding component used in machining operations where repeatable tap alignment and secure grip are critical. Machinists and toolroom technicians install this collet when setting up tapping stations on CNC machining centers, drill presses, or manual tapping arms.

This collet is suited for hand tap applications in both production and job-shop environments. It is compatible with M6 and M6.3 taps and fits into ANSI 1 series tap holders. The 19/11-4063 does not support through-coolant delivery and is not rated for tension-compression (floating) tap holders. Typical use cases include general-purpose tapping in ferrous and non-ferrous materials where a rigid collet-style grip is preferred over a floating chuck.

Key Features

• ANSI Series 1 collet format for broad compatibility with ANSI 1 tap holder bodies
• 0.255 inch bore diameter matched to M6 and M6.3 tap shanks
• 0.191 inch square drive size for positive torque transmission
• Hand tap configuration - rigid hold without tension-compression float
• No through-coolant passages, keeping the design simple and cost-effective for dry or flood-coolant setups

Compatibility

Designed for use with M6 and M6.3 hand taps in ANSI Series 1 tap holders. Bore size of 0.255 inches and square size of 0.191 inches must match the tap shank being used. Not compatible with tension-compression tap holders or through-coolant tooling systems.

Installation Notes

A qualified machinist or toolroom technician should install this collet. Ensure the tap holder and spindle are fully de-energized and at rest before inserting or removing the collet. Confirm the tap shank diameter and square size match the collet specifications before assembly to avoid slippage or damage during operation. Follow the tap holder manufacturer's torque and retention guidelines when securing the collet body.
