Titanium Nitrided Bearing Nut • Simple reliable design - more efficient than conventional ball bearing built-in nut. Good sliding effect due to surface hardness of HV2,200 and TiN coating. No corrosion occurs internally. Reduced micro vibration with collet flange contact. Increase cutting performance with improved tool life and durability. Greater cutting rigidity. Increased gripping power • The smaller the taper angle, the better the concentricity achieved. Steep 8° collet is seated deeper within the body of the holder, providing double the clamping force and twice the precision of traditional...

Superior SK Coolant System Our Slim Chuck collet is unique and high-pressure coolant ready which means no compromise in performance and higher accuracy and gripping torque is maintained as standard. SK Coolant Through Options Slotted Disc: When the optional Jet Coolant Nut is paired with its corresponding Slotted Jetter Disk, coolant is directed around the cutting edge of the cutting tool. This makes this combination ideal for non-coolant through tools. The jet coolant pressure supplied through the disk creates a tornado effect ensuring efficient swarf dispersal. Applications for Nikken SK J...
