Descriptions:
1. Straight flute design, downward chip removal. Right hand thread cutting, clear threads, fast tapping with accuracy. Titanium coating can improve wear resistance, corrosion resistance and rust protection.
2. High speed steel (HSS) tool with cobalt has higher hardness and precision, better wear resistance and toughness, higher heat resistance. It is made by adding 5%-8% cobalt to the general-purpose high-speed steel.
3. Suitable for processing through holes or shallow holes . Perfect for tapping stainless steel, alloy steel, copper, aluminum, etc.. Micro taps are mainly used for watches and clocks, and drilling materials in low hardness, such as wood, plastic and soft metals.
4. Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Please add coolant when tapping and apply anti-rust oil for maintenance after use to prolong the service life.
5. Machine taps are suggested to be used with tap collets with overload protection. Hand use or electric drill use is easy to cause breakage to the tap, not recommended. Recommended feed rate: General steel: 6-15m/min; harder steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min.
