Product Overview: Powder Metallurgy Fluteless (Form) Tap Steel-Use Metric – 5KC 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 metric form tapping thread strength and tool durability.
• Fluteless Form Tapping Design: Features a fluteless (cold forging) tapping principle that forms threads through plastic deformation rather than material removal — recommended for blind hole and through-hole tapping of ductile materials such as carbon steel and stainless steel, where the work-hardened thread surface achieves significantly higher strength than cut threads, while completely eliminating chip generation and evacuation concerns.
• 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 form tapping of steel, stainless steel, and superalloy materials, providing superior tool life compared to standard HSS and HSS-CO.
• TiAlN Premium Coating Enhancement: The surface is treated with TiAlN coating, providing outstanding heat resistance and oxidation resistance — recommended for form tapping of high cutting temperature materials such as superalloys, maintaining outstanding wear resistance performance even under high forming torque and elevated temperature conditions, significantly extending tool change intervals.
• 10 Metric Specification Precise Coverage: Available in thread diameter 2–16mm and pitch 0.4–2mm across 10 specifications — recommended as the dedicated high-performance stock tool for steel and stainless steel metric form tapping.

【Machining Applications & Uses】

• Primary Use: Metric precision form thread forming, high-strength threaded hole production, and NC machining center chip-free metric automatic tapping.
• Recommended Work Materials:
  • P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC35, where HSS-PM combined with TiAlN coating delivers stable form tapping performance, with formed thread strength superior to cut threads, representing the core recommended application scenario for this series.
  • M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the form tapping design completely eliminates continuous chip formation and evacuation issues, while the TiAlN coating effectively suppresses cutting heat accumulation during the forming process, recommended for use with appropriate cutting fluid.
  • S-Class (Superalloys): Nickel-based alloys and other high-temperature superalloys — the TiAlN coating's outstanding heat resistance and oxidation resistance provides stable superalloy form tapping performance, recommended for use with appropriate cutting fluid.
