HSK-CK series side lock tool holders are manufactured from high-strength alloy steel with overall quenching and precision grinding, making them the preferred choice for heavy cutting operations on CNC machining centers.
  1. Side lock set screw clamping system provides extremely high clamping force and rigidity, capable of withstanding high-torque cutting and effectively preventing tool slippage.
  2. High-precision taper fit with runout accuracy ≤0.005mm ensures consistent machining dimensional stability and surface quality.
  3. Full range of specifications covering HSK40A/HSK50A/HSK63A/HSK80A/HSK100A spindle interfaces, with multiple clamping diameters and overhang lengths available.
  4. Black oxide surface treatment provides excellent anti-rust and wear resistance for long service life.
