FOCMKEAS 2 PCS Metric Machine Tap M3 x 0.5, HSS 6542 Screw Tap H2, 3 Straight Flutes Thread Hole Repair Tools, Screw Milling Threading Machinist

【SIZE】Thread size: M3 x 0.5; thread tolerance: H2; thread length: 14mm/0.55"; square shank width: 3mm/0.12"; overall length: 50mm/1.97" 【FEATURE】Heat treated HSS 6542 provide high hardness and toughness. Straight flute design, rapid downward chip removal for efficient threading, clear threads without burrs, right hand tapping direction. 【APPLICATION】Make or repair thread, cutting compound introduction can protect tap. suitable for most metals, copper, alloy steel, cast iron, aluminum, brass, abrasive steel, A3 steel, iron plate etc. 【USAGE】Great for through-hole and shallow hole. Machine taps used with drilling machines, tapping machines, automatic machines, machining centers, CNC, milling machines, not recommended for hand and electric drill tapping. 【TIPS】Drilling diameter please refer to pictures. Control speed based on material hardness during using. ordinary steel: 6-15m/min; harder steel material: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min.
Applications & Features:
Suitable for processing through-hole/shallow internal threads. Make new female threads or re-thread damaged female threads in stainless steel, ordinary steel, copper, aluminum, iron, alloy steel, hard plastic. Machine taps are used in tapping machines, vertical drilling and milling machines. Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps.

Useful Tips:
Control speed based on material hardness. Feed rate (recommended): ordinary steel (copper aluminium alloy): 6-15m/min; hard steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. The higher the hardness, the slower the speed. Fast speed and low torque; slow speed and high torque.
When tapping plastic, add lubricating coolant. For steel, motor oil is generally used, and vegetable oil is used for high requirements. Use No. 35 motor oil for stainless steel.
