Techniks 05554 Rigid Tap Collet ER25 11 Mm M14

Product Description

The TECHNIKS 05554 is a rigid tap collet designed for use in ER25 collet chucks. It holds M14 hand taps securely during rigid tapping operations, eliminating the axial float found in tension-compression tap holders. The collet accepts an 11 mm shank with a 9 mm square drive engagement, providing positive rotational drive and repeatable tap alignment. Rigid tap collets of this type are used by CNC machinists and tool-and-die professionals who require precise thread depth control in synchronous tapping cycles. Through-coolant is not supported on this collet.

This collet fits standard ER25 collet chucks and is suited for rigid tapping of M14 threads in ferrous and non-ferrous materials on machining centers with synchronous spindle control. It is appropriate for production environments where consistent thread depth and minimal tap runout are required. The hand-tap configuration makes it compatible with standard hand-style tap shanks rather than pipe tap profiles. Typical applications include general-purpose threading in CNC milling and machining center operations.

Key Features

• ER25 collet series - fits any standard ER25 chuck body
• 11 mm collet bore accommodates M14 tap shank diameter
• 9 mm square drive engagement transmits torque directly to the tap
• Rigid (non-tension) design supports synchronous tapping cycles with depth accuracy
• Hand tap geometry - not configured for pipe taps
• No through-coolant passage

Compatibility

Designed for use in ER25 collet chucks with M14 hand tap shanks requiring an 11 mm bore and 9 mm square drive. Compatible with machining centers that support rigid synchronous tapping.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down the spindle and confirm the machine is in a safe, locked-out state before changing tooling. Seat the collet fully into the ER25 chuck nut before torquing the nut to the chuck manufacturer's specified value using the appropriate ER spanner wrench. Verify tap runout with a dial indicator before beginning production cuts.
