Name: tap Ti / screw tip apex machine (yellow section)
Material: high quality M2 River metallurgy material (HSS)
Surface treatment: TiN coating (increasing surface finish / hardness and red hardness)
Spiral point tap is also called end tap，Generally, there are 4-5 cutting edges, which further reduces the cutting amount of each tooth, increases the relative strength of the cutter tooth, and improves the service life of the tap. In general, spiral fluted tap of screw tap life will extend over at least 1 times at the same time, the cutting speed of spiral fluted tap generally can be increased by more than 50%.
Suitable for cutting material: it is suitable for through-hole machining of quenched and tempered steel and nickel chromium manganese steel (30Gr/40Gr/40GrMn), showing excellent machining characteristics and durability. It is suitable for all kinds of heat-resistant steel and ordinary steel, especially in high speed and high dilution conditions can exert excellent cutting ability.Can.
