DESCRIPTION
- RR Brand keyless drill chucks are designed for CNC/VMC machining centers and milling machines.
- Engineered to withstand super heavy torque applications with excellent runout accuracy.
- The self-tightening mechanism automatically increases the grip in proportion to the increase in torque during the drilling and prevents the tool from slipping in a clockwise rotation.
- Supplementary Gripping Torque can be applied with the spanner which increases the gripping torque by up to 3 times.
