Specifications: Metric Thread Size: M4 x 0.7 Tolerance: H2 Thread Length: 22mm / 0.87" Square End Size: 3mm / 0.12" Round Shank Dia.: 4mm / 0.16" Total Length: 100mm / 3.94" Blade Length: 28mm / 1.1" Material: M35 Cobalt High-Speed Steel (M35 HSS-CO) Finish: Titanium Coated Cutting Direction: Right Hand Package Included: 2pcs x Straight Flute Thread Taps Descriptions: The tapping tool adopts straight flute design, clear threads, and right hand cutting direction. Threading tap provides rapid downward extra removal to achieve efficient thread cutting, suitable for processing through holes or shallow holes. Screw thread tap can create new threads or re-thread damaged or jammed threads. Widely used for most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, 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. M35 cobalt high-speed steel taps offer improved hardness, wear resistance and cutting performance, as well as excellent heat resistance and higher strength. Titanium coating provides excellent corrosion resistance, and reduces the coefficient of friction for smoother tapping. 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.
