Uxcell 5/16-24 UNF 2B High Speed Steel(HSS) Uncoated Machine Spiral Flutes Thread Tap

Spiral flute design upward chip removal. Right hand thread cutting clear threads fast tapping with accuracy. 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. Suitable for processing blind holes and sticky materials. Great for drilling and tapping aluminum die steel stainless 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 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. Hand use is easy to cause breakage to the tap due to uneven force. 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.
