M4 x 0.7 Spiral Flute Thread Tap, Metric Machine Threading Tap HSS Nitriding Coated, Round Shank with Square End, H2 Tolerance, 2pcs

M4 x 0.7 Spiral Flute Thread Tap - HSS Nitriding Coated, Round Shank with Square End, H2 Tolerance, 2-Pack
✔️ M4x0.7 spiral flute, right-hand, nitriding-coated HSS, 2-piece set

These taps are designed for precision machine threading with a spiral flute that lifts chips out of the hole, making them ideal for blind holes and sticky materials. The M4 x 0.7 metric size ensures compatibility with many common components in automotive, electronics, and DIY projects, and the nitriding-coated high-speed steel boosts wear resistance and rust protection for longer tool life. The round shank with a square end provides secure drive in CNC, tapping, drilling, and milling setups, reducing slipping under heavy cutting. For best results, use tapping oil and proper collets with overload protection; avoid bare-hand tapping to prevent damage and ensure consistent threads.

✅ Tap size: M4 x 0.7, H2 tolerance ✅ Flute: Spiral for upward chip removal ✅ Material/finish: HSS with nitriding coating ✅ Shank: Round with square end for solid drive ✅ Applications: Blind holes, sticky materials; suitable for aluminum, die steel, stainless steel, bronze, hard plastics
