Features Tungsten carbide steel: the cutter with 2mm cutting edge diameter is made of tungsten carbide steel with good milling and cutting performance, ensuring high working efficiency TITANIUM COATING TREATMENT - The surface of double edge end mill is treated with a titanium coating, which increases the rust resistance of the product. The cutting tool set has sufficient bending resistance, wear resistance and high hardness Single edge design: the sharp blade has a single edge design, the cutting edge is sharp, the cutting surface is smooth and the chip removal is smooth. It can be used for milling holes, grooves and edges on the plate and the processing process becomes smooth. Polishing treatment: tungsten carbide steel is polished, the surface is smooth and clean, the cutting edge is sharp, the handle has no burrs and will not hurt your hands. You can use it with confidence Application: straight shank drill bits can be used to engrave many items or materials such as circuit boards, hardware parts, plastics, copper and stainless steel, and can also work various metals, plastics, resins, density boards, wood and other density boards Functions: These cutters are made of tungsten carbide steel with good milling and cutting performance and ensure high working efficiency. Straight shank drill has sufficient bending resistance, wear resistance, high hardness, high wear resistance and high strength. Sharp cutting edges, can be used for milling holes, grooves and edges on plates and the process becomes smooth. Well polished surfaces are pretty clean, tidy and there are no interference or burrs on the shaft. Many items or materials such as circuit boards, hardware parts, plastics, copper and stainless steel can be engraved. Specifications: Material: tungsten carbide steel.
