Information Taps has straight flute thread taps, spiral flute thread taps, spiral point thread taps and thread forming taps. They are also classified into hand taps and machine taps according to the usage. Be sure to select the appropriate cutting oil for complex tapping process and apply anti-rust oil for maintenance after use. Straight Flute Taps Straight flute design, downward chip removal. clear threads, fast tapping with accuracy. Titanium Coating Provides excellent corrosion resistance, greatly improves wear resistance and hardness, and reduces the coefficient of friction. High Speed Steel Tool Features high hardness, high red hardness, wear resistance, good toughness, suitable for a wide range of applications. Used on drilling and tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Cutting oil is lubrication, cooling and anti-sticking. Wide Applications Suitable for processing through holes. Used for drilling and tapping stainless steel, aluminum, die steel, bronze, hard plastics, etc.. 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 Tips 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. 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 (such as M1-M3.5) are mainly used in clocks and watches, tapping wood and soft metals with lower hardness.
