- Spiral Flute Taps: Thread size M4 x 0.7 + 0.03; Square size 4mm / 0.16". Designed with a spiral tip for effective chip removal and precise threading, ensuring a smooth and efficient cutting process. - Durable Titanium Coating: Offers exceptional corrosion resistance, enhances wear resistance and hardness, and reduces friction, ensuring longer tool life and consistent performance. - Versatile Applications: Ideal for threading through-hole applications on materials such as aluminum, tool steel, stainless steel, bronze, and plastic. Recommended feed rates: general steel 6-15 m/min; harder steel 5-10 m/min; stainless steel 2-7 m/min; cast iron 8-10 m/min. Avoid excessive feed rates to prevent tap breakage. - Custom Fit Design: Increased tap size accommodates workpieces requiring post-threading processes like galvanizing or sandblasting. Generally, a thickness reinforcement of 0.03-0.1 mm is advisable, offering high hardness, toughness, wear resistance, and heat resistance. - Easy to Use: Compatible with drilling and threading machines, CNC mills, and milling machines. Utilizing tapping oil results in superior threads and enhances the longevity of taps. It is recommended to pair with overload-protected tapping collets for optimal safety and efficiency. Ideal for professionals seeking reliable threading solutions, this tap provides the durability and precision needed for high-quality results in various machining tasks.
