Techniks 19/11-4048 Tap Collet Ansi 1 0.194 Inch

Product Description

The TECHNIKS 19/11-4048 is an ANSI 1 series tap collet designed to hold hand taps in toolholding systems that accept the ANSI collet standard. With a collet size of 0.194 inches and a square drive size of 0.152 inches, this collet securely grips M4.5 and M5 hand taps during threading operations. It is used in CNC machining centers and manual setups where precise tap retention and repeatable positioning are required. Machinists and tool crib personnel working in production or job-shop environments will find this collet suited for standard hand-tap applications without through-coolant or tension-tap requirements.

This collet fits ANSI 1 series tap holders and is appropriate for threading operations using M4.5 and M5 hand taps. It is intended for dry or externally cooled applications, as through-coolant is not supported. Typical use cases include light threading in metalworking environments where a reliable, close-tolerance collet interface is needed to maintain tap alignment and reduce tap breakage risk.

Key Features

• ANSI 1 collet series for compatibility with standard ANSI tap holders
• 0.194 inch collet bore sized for M4.5 and M5 hand taps
• 0.152 inch square drive size for positive tap engagement
• Hand tap configuration - no tension-tap mechanism
• No through-coolant passages, suited for dry or flood-cooled external setups

Compatibility

Designed for use with M4.5 and M5 hand taps in ANSI 1 series tap collet holders. Verify holder series and square size requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle or tap holder is fully de-energized and the machine is in a safe lockout state before seating or removing the collet. Confirm collet bore and square dimensions match the tap shank before tightening the holder to avoid collet damage or tap slippage. Inspect the collet seating surface for debris or wear before each use.
