Cutter’s alloy head use special hard rock alloy( patent), outside structure use coronary step type(patent), it can protect the body’s abrasive resistance efficiently.3.The No spark of wear–resisting layer is Cladded on the Matrix’s tooth end, and its surface hardness is above 60HRC, and cutter handle hardness is from 38 to 42HRC.Alloy head shape：1. CAPOur market leading cap carbide tips are best suited for soft tomedium-hard materials and applications. A valve seat braze jointincreases strength and shear resistance. These tips offer superiorpenetration, and the larger carbide shoulder provides excellentprotection against steel wash.The specific size: Φ17.5mm*16mm、Φ20mm*18mm、Φ22mm*20mm、Φ25mm*19mm  Φ30mm*27.5mm2. INSERTInsert carbide tips prevail in high impact conditions or whenworking with hard materials. These industry leading tips areideal for penetration applications where steel wash is not an issue.The specific size: Φ16mm*24mm、Φ19mm*25mm、Φ19mm*29mm、Φ20mm*28m、Φ20mm*30mm、Φ22mm*30mm、Φ22mm*34mm、Φ25mm*35mm、Φ25mm*38mm 、Φ27mm*35mm、Φ27mm*38mm 、Φ30mm*38mmPacking :Plastic case/wooden box
