Craftsmanship
-
Mirror Finished
Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance
-
Pilot Contact
Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity
-
Taper End Face
Precision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidity

High Torque Collet Nut
The maximum torque is laser marked on the ER collet nut face to take the guess game out of the way to ensure proper amount of force should be applied while tightening. Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material. -
Compatible with Standard ER Collet
Although the tool holder is compatible with standard ER collet, it's recommended to use ER Rigid Tap collet which has a square design slot in the rear end of the collet to lock in on the flat-sided shank, preventing the tap from spinning inside. On Tegara ER rigid tap collet, the bore size and square size are laser marked on the collet body for easy identifying tap size.
Mirror Finish
To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.
