Tap Collets and Holders

Hardinge

TT Floating Tap Holder Collets

TT Tap Holder Collets are used exclusively in the Hardinge TT Tap Holders –
5 â„
8 " and
3 â„
4 " round shanks. Each collet is made for a specific tap size. A square broached hole securely holds the shank of the tap, eliminating tap slippage and misalignment.

Collet-Type Releasing Tap Holder

The Collet-Type Releasing Tap Holder is used to provide thread length control on either right- or left-hand industrial taps by switching a lever inside the body of the tap holder. The tap holder mounts directly into a round shank tool holder. TT-style tap holder collets are used for accurate holding and centering of taps. To provide a positive drive for the taps, the collets have a square slot in the back to accommodate the square on the tap shank and a notch in the back bearing of the collet that fits over a hardened pin in the bottom of the holder.

GK Self-Feeding – Length-Control Tap Holder

The Self-Feeding (Pafix) Tap Holder provides automatic thread length control. The tap holder eliminates the need to match feed rate to thread pitch, minimizing tool breakage. The holder has a
5 â„
8 " shank diameter. Thread length is controlled internally with an adjusting ring in .01" (.25 mm) increments. A driver is used in the holder to accommodate the square of the tap shank, providing a positive drive. A collet is used to centralize and hold the tap in the holder.

“Cool Stop" Coolant Seals

Maximize coolant flow through your drills with the “Cool Stop" system. “Cool Stop" Seals are designed to industrial seal around the shank of the drill and ID of the ER and TG holders. The gauge length of the holder does not change. The collet stays flush with the cap because the “Cool Stop" seal locates at the back of the collet. Each “Cool Stop" has a range from rated size down to .020" (5.0 mm), resulting in a small seal inventory for each collet style. You can keep the coolant running through the drill (rather than out the collet) at pressures up to 1500 psi.
