The point mosaics tungsten carbide, the surface hardness is above HRC85 degree, resistant to wear and tear, the accuracy is reliable(less than 0.01).

• The taper shank is made from high quality steel, the quenching hardness is between HRC40 and HRC45, it will be durable and wear-resisting after quenching.
• Material: the top point is made from carbide, the handle is made from 45#steel.
• The alloy top hardness: larger than HRC85.
• The handle hardness: between HRC40 and HRC45.
• Central angle: 60 degrees.
• The total length: 100mm.
