Simple and Rigid: Titanium Nitrided “TiN Bearing” Built-in Nikken’s Unique Nuts

Nikken’s unique TiN Bearing built-in nuts is more efficient than conventional ball bearing built-in nut. It has good sliding effect due to surface hardness of HV2,200. Extreme hard and smooth surface of the TiN Bearing allows for more thrust load on the collet while preventing additional runout associated with collet twisting and narrow body design accesses tight spots. It increase cutting performance and tool life durability.

Twice More Clamping Force and Twice More Precision: Nikken’s Unique Steep ８゜Taper Collets

The smaller the taper angle is, the better concentricity is obtained. Nikken’s steep 8° collet seats deeper in the body of the holder, providing twice more clamping force and twice more precision than traditional 16° ER collets. Collet edge is flush with front surface of nut maximizing gripping rigidity.
