1. Spiral flute tap: thread size: M6 x 1 0.1; square size: 5 mm / 0.2 inch. Spiral groove design, upward chip removal, fast thread cutting with accuracy. Titanium coating provides corrosion resistance, improves wear resistance and hardness, and reduces coefficient of friction. 2. Wide applications: suitable for machining blind holes and sticky materials. For thread cutting aluminium, tool steel, stainless steel, bronze and plastics. Recommended feed speed: general steel: 615 m/min; harder steel: 510 m/min; stainless steel: 27 m/min; cast iron: 810 m/min. The torque caused by too fast feed speed is too large, which can easily lead to the tap breakage. 3. Special design: enlarge the tap to adjust it to the workpiece requirements. It has a hardness and toughness, wear resistance, heat resistance. 4. Easy to use: use on drilling and thread cutting machines, CNC and milling machines. Use thread cutting oil to get higher quality threads and more durable taps. It is recommended to use machine tap drill with thread cutting pliers with overload protection.
