기능

• Uses unique groove shape and cutting tool angle to improve chip discharge.
• Heel cutting performance has been improved to accurately cut chips at the depth of the screw and eliminate remaining chips.
• Since there is no chip residue, blade chipping trouble at the chamfered part that is likely to occur during reverse rotation is greatly reduced.
• The special shape of the threaded part is effective in preventing chipping of the blade of the perfect thread, reducing tapping torque and frictional resistance, and maintaining screw guiding properties.
• For blind hole machining.
• Work Material: For low carbon steel, medium carbon steel, high carbon steel, alloy steel, tempered steel (25~35HRC), stainless steel, cast steel.
