BT30 ER16 70 Mill Tool Holder, High Speed Collet Chuck Holder 10000rpm 20CRMnTi Steel CNC Mill Holder

• Made of high quality steel material for long service life
• Small body and it has stable performance
• The nut is designed with no wind resistance to ensure more stable machining at high speed.
• It has high heat strength and oxidation resistance, strong toughness and super wear resistance.
• The close cooperation of the cutting force of the tool on the workpiece to the guide column reduces the resonance and makes the machining accuracy more stable.
