기능

• This roll tap is suitable for machining steel materials (35HRC or less) and light alloys, and supports high-speed machining (20~50 m/min).
• Stainless steel and temper materials (~40HRC) can now be processed.
• The machining torque has been reduced by more than 20% and the life has been greatly increased compared to the conventional product.
• It can now be used with water-soluble cutting fluids.
• Torque reduction heave tap (Patent No. 3822572) is adopted in the design specifications.
• For through-hole machining.
• Work material: low carbon steel, medium carbon steel, high carbon steel, alloy steel, tempered steel (25~35HRC), stainless steel, aluminum alloy casting.
