Spiral flute design, upward shavings removal High speed steel tap has high hardness, excellent toughness, and abrasion resistance. Black nitrogen treatment greatly improves abrasion resistance, corrosion resistance and high temperature resistance. The round shape has excellent abrasion resistance.
Round shape can be used with a die wrench (sold separately). Insert the fixing screw in the middle of the wrench into the slot of the die to tighten it. Machine taps are used in drill press, tapping machines, CNC, milling machines, and are recommended for use with tap collets with overload protection.
Recommended feed rate: General steel: 6-15m/min; Hard steel: 5-10m/min; Stainless steel: 2-7m/min; Cast iron: 8-10m/min. Because the torque generated due to the feed speed is too large, the tap may be easily damaged.
