Carbide screw inserts for metal cutting are used for welded milling cutter to mill cut different grades steel and other metals in a wide range of demanding industrial applications, such as autos, motorcycles, aviation, aerospace, shipbuilding etc.
Carbide Screw Inserts Features
1. High hardness suitable for cutting steel and other metals
2. High strength for constant cutting
3. Long life to reduce cost
Carbide Screw Inserts Applications
Carbide screw inserts are welded with milling cutter steel body suitable for milling steel and other metal materials, even for the sharp corner and half-circle convex shape. Carbide screw inserts and tips have advantage of high-precision. Professional cutting tools with carbide tips are applicable for all kinds of heavy milling processing such as Machine Processing Industries, Metal Mold Industries, Automotive & Automotive Accessories Industries etc.
Finishing End Mill is welded with carbide flutes and suitable for side milling and groove machining for finishing surface.
