Our JIS HSS‑M2 Spiral Point Form B Machine Tap Set contains 11 pieces of TiN‑coated machine taps, specially engineered for through‑hole threading. The spiral‑point Form‑B design directs chips forward through the hole instead of backward, avoiding chip clogging inside the threaded hole and delivering smooth threading performance for automated or CNC machine tapping applications.
Core Construction
Standard: JIS industry standard, stable thread dimensional accuracy
Material: HSS‑M2 high‑speed steel substrate, offers high hardness and toughness
Surface Finish: TiN (Titanium Nitride) coating. Reduces friction, improves wear‑resistance, extends tool service life and lowers cutting heat during tapping
Flute Type: Spiral Point Form B (gun point), chip forward ejection, dedicated for through‑holes
Packaging: Transparent plastic storage box for safe keeping, easy inventory and transport
Key Features
✅ JIS Standard Specification: Consistent thread profile for reliable tapping results
✅ HSS‑M2 High‑Speed Steel Base: Balanced hardness and toughness for metal cutting
✅ TiN Coating: Lower friction coefficient, anti‑abrasion, longer tool lifespan
✅ Spiral Point Form‑B Geometry: Forward chip evacuation, prevents chip jamming, optimized for through‑holes
✅ 11‑Piece Complete Set: Covers multiple common thread sizes for versatile workshop requirements
✅ Clear Plastic Storage Case: Protect taps against damage, convenient for storage & carrying
Application Scenarios
Designed for machine tapping, CNC machining and mass‑production workshop tasks. Suitable for carbon steel, alloy steel and general ferrous metals. Mainly for through‑hole threading, not recommended for blind holes. Widely used in machinery manufacturing, auto‑part processing, maintenance & repair workshops.
Working Note
Spiral‑point Form‑B taps push chips ahead of the cutting edge. Please confirm your workpiece is a through‑hole before tapping operation. For blind‑hole threading, spiral flute taps are suggested as alternative tooling.
