NT30 APU Self-Tightening Drill Chuck Holder - Made In India
Range 1-16mm, Taper Nt30 or ISo 30
Upgrade your machining setup with this premium NT40 APU Series Self-Tightening Drill Chuck Tool Holder, engineered for high-precision drilling and superior holding power in professional workshop environments.
Manufactured from high-quality 20CrMnTi alloy steel, this tool holder is heat treated to achieve a hardness of 56±2 HRC with a carburized layer depth exceeding 0.8mm, ensuring exceptional wear resistance, durability, and long service life.
The self-tightening drill chuck mechanism automatically increases clamping force as drilling torque rises, providing a secure grip on drill bits and significantly reducing the risk of slippage during heavy-duty operations.
Featuring an integrated shank and chuck body design, the holder offers excellent rigidity and eliminates the possibility of separation between components, resulting in improved machining stability and accuracy.
Additional quenching treatment has been applied to critical stress areas to enhance strength and resistance to breakage under demanding machining conditions.
