Product Overview: Powder Metallurgy Stainless Steel Spiral Point Tap Metric – 5SPMP Series

【Product Features & Why We Recommend It】

• French Brand Professional Quality: Originating from a professional French cutting tool brand with rigorous quality control — recommended for users with high demands on stainless steel metric thread tapping accuracy and tool durability.
• Stainless Steel Dedicated Optimized Design: Features a tapping geometry specifically optimized for the difficult-to-machine characteristics of stainless steel — including high toughness, susceptibility to work hardening, and continuous chip formation — recommended for precision stainless steel thread machining applications where standard taps are prone to tooth chipping or tap breakage due to adhesion or work hardening.
• HSS-PM Powder Metallurgy High-Performance Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), delivering extremely uniform carbide distribution, outstanding toughness, and wear resistance — recommended for long-duration stable tapping of difficult-to-machine materials such as stainless steel, providing superior tool life and thread consistency compared to standard HSS and HSS-CO.
• Spiral Point Through-Hole Design: Features a spiral point tap design that pushes chips forward and out of the hole — recommended for stainless steel through-hole tapping operations, effectively managing continuous chip evacuation to ensure smooth tapping and thread accuracy.
• 14 Metric Specification Precise Coverage: Available in thread diameter 2–12mm and pitch 0.4–1.75mm across 14 specifications — recommended as the dedicated high-performance stock tool for metric through-hole tapping of stainless steel and carbon steel materials.

【Machining Applications & Uses】

• Primary Use: Stainless steel precision metric through-hole thread tapping, carbon steel and alloy steel high-quality thread forming, and NC machining center stainless steel automatic tapping.
• Recommended Work Materials:
  • M-Class (Stainless Steel): SUS304, SUS316, SUS420, and other high-toughness stainless steel — the dedicated core recommended application scenario for this series, where the stainless steel dedicated geometry combined with HSS-PM powder metallurgy substrate effectively addresses the unique stainless steel tapping challenges of work hardening, continuous chip formation, and adhesion, recommended for use with appropriate cutting fluid.
  • P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC35, where the HSS-PM substrate delivers stable and long-lasting through-hole tapping performance.
