Description:
Straight flute design Right Thread, Clear Thread, Accurate Fast Tapping
High speed steel tools have high hardness and toughness, wear resistance and heat resistance. Suitable for general threading applications only on non-coated surfaces.
Suitable for processing through holes and shallow stop holes. Used for drilling and tapping aluminum, stainless steel, copper, hard plastic, etc. Use with tapping oil for better screw and more durable taps.
Used in drilling machines, tapping machines, CNC, milling machines. Recommended feed speed: General steel: 6-15m/min; Harder steel: 5-10m/min; Stainless steel: 2-7m/min; Cast iron: 8-10m/min; The feed speed is too fast to increase torque and make the tap break easier.
Machine taps are recommended to be used with tap collets with overload protection. We do not recommend using it by hand or using an electric drill, as it is prone to damage the tap. When tapping processing, injecting coolant liquid and applying rust resistant oil to maintain after use, it can be used for longer.
