Thread Size: M1.6 x 0.35mm. High-speed steel metric taps are with high hardness and toughness for wear resistance, well suited for general purpose applications.. The thread tap can make new threads or re-thread damaged or jammed threads. Uncoated taps feature just the base substrate without any additional coatings, and fit a wide range of applications.. Suitable for processing through holes or shallow holes on most metals, iron plate, copper, zinc, alloy steel, abrasive steel, A3 steel, stainless steel, etc.. Add appropriate tapping oil for higher quality internal threads and more durable taps.. Standard metric thread design, clear and tidy, provide rapid chip removal for efficient threading. Straight flute design, right hand tapping direction. The mini metric taps are mainly used for clocks, watches, low hardness wood and soft metal hole processing.. Machine taps used with drilling machines, tapping machines, automatic machines, machining centers, CNC, milling machines, not recommended for hand and electric drill tapping. Recommended feed speed: ordinary steel: 6-15m/min; harder steel material: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min..
