Spiral Flute Thread Tap M4 X 0.7 Metric Machine Taps HSS Titanium Nitride

Specifications: Metric Thread Size: M4 x 0.7 Tolerance: H2 Thread Length: 9mm / 0.35" Square End Size: 3.4mm / 0.13" Total Length: 67mm / 2.64" Material: M2 High-Speed Steel (HSS6542) Finish: Titanium Nitride Coated Cutting Direction: Right Hand Package Included: 1 x Spiral Flute Thread Taps Descriptions: The spiral flute design ensures smooth chip evacuation, prevents breakage, and enables more efficient tapping. The spiral tip of the tap helps guide it into the hole, reducing the torque required to turn it, and the flutes easily remove chips and debris from the hole and machine. Spiral flute thread taps are suitable for machining blind or deep holes and sticky materials, and can be used for tapping stainless steel, aluminum, cast iron, alloy steel, ordinary steel, non-ferrous metals, hard plastics, etc. Suitable for drilling machines, tapping machines, CNC machine tools and milling machines. Used with tapping oil, you can get more precise threads and more durable taps. Taps are made of M2 high-speed steel, It has high hardness, toughness and good wear resistance, good cutting performance, and can produce clean and precise holes. Titanium nitride coated has wear resistance, high temperature resistance, and corrosion resistance, allowing it to maintain stable performance during high-speed machining. It is recommended to use machine taps with tap chucks with overload protection. It is not recommended for manual use and electric drill tapping to avoid damage caused by uneven force. The tapping angle should be 90 degrees vertical. The harder the material, the slower the drilling speed.
