Taper is precision ground to AT3 or better to ensure rigid taper contact
Tool holder body is made from drop forged alloy steel and heat treated to 56-60HRC
Innovative coating process on the ER collet nut significantly increase the gripping force by 75%compared to standard ER collet nut
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.
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.
Asymmetrical O-Ring
Internal clamping ring's shape is design to minimize out-of-balance compare to the standard off-center o-ring design from other standard ER collet nut, achieving 12,000 RPM without needed to drill holes on the collet nut body when placed on a dynamic balanced machine to preserve ER collet nut's body strength.
