Description:

Spiral Flute Taps: Thread Size: 12-24 UNC; Tolerance Grade: 2B; Square End Size: 5mm / 0.2". Spiral flute design, upward chip removal. Right hand thread cutting, clear threads, fast tapping with accuracy.. High-speed steel tool: High speed steel tool has high hardness and toughness, heat resistance and wear resistance. Features the base substrate without any coatings. Fit for most general purpose thread tapping.. Wide Applications: Suitable for processing holes and sticky materials. For drilling and tapping aluminum, die steel, stainless steel, bronze, hard plastics. 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.. Easy to Use: Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap collets with overload protection.. Tips: Taps are prone to chipping or breaking due to speed overload or non-vertical tapping. Use the correct tapping tools, such as tapping wrench, tapping machine. Micro taps are mainly used in clocks and watches, as well as for making holes in wood and soft metals with lower hardness..
