High Accuracy CNC APU Drill Chuck Holder with BT Shank

Basic Info Model No.: BT40-APU13 Material: 20CrMnTi HARDNESS: 58±2HRC Carbon Depth: >0.8mm Run Out: 0.005mm 0.008mm Product Description Features: 1.Jaws titanium, improve the wear resistance,surface coating. 2.Integrated design of the rob and collet, can avoid the collet and rob separate. 3.High accuracy,strong grasp force, and high stability. 4.Self-tightening, grasp the collet slightly, when drilling, grasp force is enhancing with the torque increasing and develop.obvious strong grasp force to prevent the drill remove. Advantage: 1.Integrated design of the rob and chuck slightly, when drilling, grasp force is enhancing with the torque increasing and develop obvious strong grasp force to prevent the drill remove. 2.Coating surface enhance surface hardness durability,anti-rust and anti-corrosion better,precison more stable,surface more smooth and appearance more nice. Attaching importance to the reserch and products,we employs many experienced and skilled technicians,so that precision machining can be made according to samples or drawings.
