Product Specifications:
This HSS spiral point tap is optimized for high‑speed through‑hole threading in stainless steel, carbon steel, and cast iron. The TiN coating (gold) reduces friction and increases wear resistance, making it suitable for production environments where consistent thread quality is required. The spiral point (gun) geometry projects chips forward through the hole, eliminating chip packing and allowing continuous tapping without reversal – ideal for CNC lathes and machining centers.
The M10x1.5 tap features a 70mm overall length and 20mm working length, with a 6H tolerance class for precise fit. With 3 flutes, it offers a good balance of core strength and chip clearance. Unlike straight flute taps, this design is not recommended for blind holes because chips are forced forward. For blind holes, consider a spiral flute tap instead.
Common applications include automotive components, machinery mounting holes, and any part where the hole is open on both ends. Custom coatings (TiAlN, CrN) and special thread tolerances are available for OEM orders. Upgrade your through‑hole tapping with this reliable, high‑productivity spiral point tap.
Spiral flute taps are ideal for blind holes (chip evacuation upward), while spiral point taps are best for through holes.Read full guide →
