Techniks 21480/30BT Tapping Chuck Rigid BT30 Taper Shank

Product Description

The TECHNIKS 21480/30BT is a rigid tapping chuck with a BT30 taper shank connection, designed for use in CNC machining centers and tapping operations where precise thread formation is required. The chuck accepts taps up to 9/16 inch (M14 metric) and delivers a 2.8-inch projection from the spindle face. Rigid tapping style means the chuck does not float axially, relying on the machine spindle's synchronized feed control to drive the tap. Quick-change capability speeds up tool changeovers on the shop floor. At 1.3 pounds, it is a compact, lightweight toolholder suited for production tapping environments.

This chuck is intended for use on BT30 taper spindle machining centers performing rigid tapping cycles. It accommodates a wide collet capacity range, from No. 0 and No. 6 inch sizes on the small end up to 9/16 inch, and from M1.6 to M14 on the metric side. Typical applications include production drilling and tapping of through-holes and blind holes in ferrous and non-ferrous materials. Machinists and CNC setup technicians are the primary installers and users of this toolholder.

Key Features

• Rigid tapping style for use with synchronized CNC spindle tapping cycles
• BT30 taper shank for direct mounting in BT30 spindle machining centers
• Maximum tap capacity of 9/16 inch (M14 metric)
• Minimum collet capacity starting at No. 0 / No. 6 inch and M1.6 to M3.5 metric
• 2.8-inch projection from spindle face for reach into workpiece features
• Quick-change design reduces tool changeover time during production runs

Compatibility

Designed for use in BT30 taper spindle machining centers equipped with rigid tapping capability. Compatible collet capacity ranges from No. 0 / No. 6 (inch) and M1.6 to M3.5 (metric) at minimum up to 9/16 inch or M14 at maximum.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in a safe state before mounting or removing toolholders. Verify the BT30 taper and retention knob are clean and free of chips or burrs before seating the chuck. Confirm the machine control is programmed for rigid tapping mode before running a tapping cycle with this chuck.
