Alloy-inlayed Metalworking Twist Drill

Alloy-inlayed twist drill is developed by the technician of the factory so as to make up the defect of low abrasion resistance of the ordinary high-speed steel in hole-drilling. The rod body uses high-speed steel, the knife bit uses mixed type hard alloy of superfine density, which makes the product much better than the high-speed steel in aspects of abrasion resistance, precision, especially the hole numbers and groom smoothness of hole-wall. Under the work condition of cutting compound or the waste oil, the product will cause its characteristic more remarkable. It is the most ideal alloy bit. Its specification may range from 4*55mm to 25*800mm, a broader scope for the user.
