Descriptions

High-speed steel 6542 has high hardness, good wear resistance, is not easy to deform, and long service life. It has good heat resistance and can still maintain stability in high-temperature environments. The surface is nitrided and blackened, which is corrosion-resistant and not easy to rust even in a humid environment.Suitable for processing through holes or shallow holes. Used for drilling and tapping aluminum, stainless steel, copper, hard plastics, etc. Use tapping oil to get higher-quality threads and more durable taps.Used on drilling machines, tapping machines, CNC, and milling machines. Recommended feed rate: general steel: 6-15m/min; harder steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. The torque caused by too fast feed speed is too large, which can easily cause the tap to break.Machine taps are suggested to be used with tap collets with overload protection. Hand use or electric drills use is easy to cause breakage to the tap, so it is not recommended. Please add coolant when tapping and apply anti-rust oil for maintenance after use to prolong the service life.
