The DIN 371/376 HSS-E M35 Spiral Flute Machine Taps are engineered for high-efficiency threading in blind holes (holes that do not go all the way through). Featuring a 35° right-hand helix (spiral), these taps act like a drill bit for chips, lifting them upward and out of the hole to prevent clogging and tap breakage.
Forged from premium M35 High-Speed Steel with 5% Cobalt (HSSE), these tools provide superior heat resistance and edge toughness, making them the industry standard for machining "sticky" or work-hardening materials like stainless steel and high-tensile alloys.

35° Helix Angle: Precision-ground spiral flutes ensure that chips are continuously pulled upward, away from the cutting zone, reducing the risk of "bird-nesting" inside the hole.
M35 Cobalt Content: The 5% Cobalt (HSSE) alloy provides extreme "Red Hardness," allowing the tool to maintain its cutting edge even when friction heat reaches critical levels in CNC machining.
Fully Ground Geometry: Ground from solid, hardened blanks to maintain 6H Tolerance. This process ensures perfectly sharp cutting edges and high-precision concentricity.
Vacuum Heat Treatment: Hardened to HRC 64-66, providing the structural rigidity required for high-torque applications in hard alloys.
Blind Hole Tapping: The primary tool for any hole where chips cannot be pushed forward.
Stainless Steel & Inox: Highly effective for 304, 316, and other austenitic stainless steels that produce long, continuous chips.
High-Tensile Alloys: Optimized for materials up to 1200 N/mm², including alloy steels, titanium, and heat-resistant castings.
CNC Production: Ideal for vertical and horizontal machining centers (VMC/HMC) where automated chip management is vital.
Premium Protection: Each tap is vacuum-sealed and housed in an individual high-impact Rose-Box plastic case.
Zero Corrosion: Coated with a proprietary high-viscosity anti-rust oil, ensuring the taps remain "factory-sharp" during long sea transits.
OEM Branding: We offer high-definition Laser Marking on shanks (Your Logo + Size + HSSE + DIN Standard).
Inventory Ready: Optimized packaging for B2B distributors, including clear size labeling and reinforced master cartons for bulk shipping.
Q: When should I use Spiral Flute instead of Spiral Point?
A: Use Spiral Flute for blind holes (chips pull up). Use Spiral Point for through holes (chips push forward). Using a Spiral Flute tap for a through hole is possible, but it is less efficient than a Spiral Point tap.
Q: Does the 35° helix work for all materials?
A: It is ideal for materials that produce long chips (Stainless Steel, Aluminum). For short-chipping materials like cast iron, a lower helix or straight flute is usually preferred.
Q: Can these be used for hand tapping?
A: While possible, Spiral Flute machine taps are designed for the constant speed and rigid alignment of CNC machines. For manual work, a standard hand tap set is generally more durable.
