Quick Details: Place of Origin: China (Mainland) Material: Tungsten Carbide Usage: Parting and Grooving Hardness: For steel Coating: PVD,CVD, Size: all standard size (customized available) Usage:Internal Turning Tool Finish Style: Finishing/ semi-finishing/ rough Products feature: 1. CNC inserts use special grade ultrafine particles tungsten carbide powder as raw material, CNC turning insert matrix has excellent strength and hardness indication. 2. CNC blade has special coating process, and the NC insert surface is pretty smooth, while keeps CNC lathe blade toughness and hardness. 3. The unique blade grooving design makes the CNC turning insert edge more sharp, so the cutting efficiency was improved 30% or more.
