High‑Performance HSS‑PM Spiral‑Flute Machine Tap
Engineered for precision and efficiency, this HSS‑PM (Powder Metallurgy) Spiral‑Flute Machine Tap delivers outstanding performance in blind‑hole thread cutting on rigid CNC and machine tapping systems:
-
Advanced Material: Made from high‑grade HSS‑PM (High Vanadium 2% and high cobalt 5%) for exceptional wear resistance and superior heat resistance (red hardness) for enabling faster, more efficient tapping in tough materials than standard HSS.
-
Optimized Spiral‑Flute Geometry: The spiral angle and length is designed to effectively minimize the chip curling and reduce cutting force to smoothly pull swarf out of blind holes, preventing clogging and ensuring consistent chip evacuation.
-
Blind‑Hole Capability: Suitable for thread depths up to approximately 3×D, with optimal cutting-edge design.
-
Broad Material Compatibility: Works excellently on materials including medium & high carbon steel, hardened steel (below HRC35) and aluminum alloy; also, effectively on materials including low carbon steel, alloy steel, stainless steel, tool steel, forged steel, grey cast iron, ductile cash iron, copper, brass and more.
