uxcell Spiral Flute Taps, M12 x 1.75 + 0.03 Metric Titanium Coated Cobalt High Speed Steel Machine Thread Milling Screw Threading Tap - a22032100ux0547

• Spiral Flute Taps: Thread Size: M12 x 1.75 + 0.03. Square End Size: 7mm / 0.28". Spiral flute design, upward chip removal, fast tapping with accuracy. Titanium coating provides excellent corrosion resistance, improves wear resistance and hardness, and reduces the coefficient of friction. Wide Applications: Suitable for processing blind holes and sticky materials. For tapping aluminum, die steel, stainless steel, bronze, plastics. Recommended feed rate: general steel: 6-15m/min. harder steel: 5-10m/min. stainless steel: 2-7m/min. cast iron: 8-10m/min. The torque caused by too fast feed speed is too large, which can easily cause the tap to break. Special Design: Enlarge the tap to suit the workpiece that needs electroplating or sandblasting after tapping. According to the thickness of the coating, an amplification of 0.03-0.1mm is generally used. It has high hardness and toughness, wear resistance, heat resistance. Easy to Use: Used on drilling and tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap collets with overload protection. Tips: Prone to chipping or breaking due to speed overload or non-vertical tapping. Use the correct tapping tools, such as tap wrench, tapping machine. Micro taps(such as M1-M3.5) are mainly used in clocks and watches, tapping wood and soft metals with lower hardness.
