The Koki Holdings America Ltd / Metabo HPT 631949000 is a precision-engineered industrial 1/4" collet assembly featuring an integrated hexagonal flange clamping nut. Designed for high-velocity rotary tools, this component is engineered to ensure maximum concentricity and safe torque transfer for industrial die grinders and routers.
Features
Double-Slit Two-Sided Clamping Geometry: Dual-slot structural profile applies uniform radial force to limit runout errors and prevent asymmetrical clamping
Integrated Flange Nut Assembly: Collet mechanically locks into the hexagonal flange nut to prevent permanent locking inside the spindle taper during bit extraction
Vibration Attenuation: Concentric machining dampens rotational harmonic resonance to protect tool bearings and reduce operator fatigue
Extreme Thermal Tolerance: Heat-treated alloy steel resists thermal expansion at high RPMs to maintain constant clamping force
ISO 9001 Integration: Manufactured under Koki Holdings strict quality control systems
Chemical Safety Compliance: Monitored under the Koki Holdings Chemical Substance Preliminary Examination System to eliminate hazardous materials
OSHA Runout Safeguards: Meets tolerances required to prevent shank slippage or catastrophic bit failure under heavy loads
