Our DIN 371/376 HSS-E M35 TiN Coated Spiral Flute Taps represent the ultimate fusion of metallurgical toughness and advanced surface coating technology. Designed specifically for blind-hole applications in high-volume CNC environments, these taps feature a 35° helix angle that pulls chips upward with mechanical precision.
The addition of 5% Cobalt (M35) combined with a Titanium Nitride (TiN) coating provides a dual layer of protection: extreme heat resistance and an ultra-low friction coefficient, making this tool the "Gold Standard" for machining stainless steel and high-tensile alloys.

Friction Reduction: The smooth TiN coating (Gold surface) reduces the coefficient of friction, preventing "chip welding" and built-up edges, which is critical when tapping "gummy" materials like aluminum or stainless steel.
Surface Hardness (HRC 80+): While the core is a tough M35 alloy, the TiN coating provides a surface hardness exceeding 2300 HV, protecting the cutting edges from premature abrasive wear.
Superior Heat Shield: TiN acts as a thermal barrier, reflecting heat back into the chips rather than the tool, allowing for higher spindle speeds and significantly longer tool life in automated CNC production.
Stainless Steel (Inox): Highly effective for 304, 316, and other work-hardening steels that generate intense heat.
Difficult-to-Machine Alloys: Ideal for alloy steels, titanium, and heat-resistant castings with tensile strengths up to 1200 N/mm².
High-Speed CNC Production: Specifically engineered for vertical and horizontal machining centers where "tool-change downtime" must be minimized.
HSS-M35 (5% Cobalt): Genuine HSSE substrate ensures the tap remains structurally sound under the high radial torque of blind-hole tapping.
Fully Ground Construction: Every tap is CNC-ground from a solid hardened blank to maintain 6H Tolerance Class and perfect concentricity.
Vacuum Heat Treatment: Controlled hardening process ensures a stable HRC 64-66 core hardness before the PVD coating process.
Q: How does the TiN coating compare to a Nitrided surface?
A: TiN is a PVD coating that offers a much harder surface and lower friction than nitriding. It is better for high-speed machining where heat dissipation is the primary concern.
Q: Why do you use DIN 371 for smaller sizes?
A: The Reinforced Shank of DIN 371 (M2-M10) provides the torsional rigidity needed to prevent the "winding" effect and snapping that often occurs in small-hole high-speed tapping.
Q: Can you provide customized packaging for our brand?
A: Yes. We offer OEM branding (Laser Marking on shanks) and customized labels for our shockproof Rose-Box plastic packaging to help you build your local market presence.
