M12 DIN 376B Maschio per filettare a macchina HSSE rivestito TiN, Forma B, 6H, foro passante

In a busy metalworking shop, a machinist reaches for this M12 tap to cut clean, precise threads in a through hole on a stainless steel bracket. The TiN coating reduces friction, while the HSSE cobalt steel withstands high temperatures, making the job faster and the tool last longer.

Key specifications

• Thread: M12 x 1.75 mm, metric coarse, tolerance class 6H
• Standard: DIN 376B, machine tap with Form B chamfer (3.5-5 threads lead-in)
• Material: HSSE (high-speed steel with cobalt) for superior heat resistance
• Coating: Titanium nitride (TiN) for reduced wear and improved chip flow
• Flute type: Straight flute, ideal for through holes
• Overall length: 140 mm, shank diameter: 9.0 mm, square size: 7.0 mm
• Reinforced shank for added rigidity during machine tapping
• Ground thread for high precision and surface finish

Why choose it

This tap is engineered for demanding production environments. The cobalt-enriched HSSE steel maintains hardness at elevated temperatures, while the TiN coating lowers friction, preventing built-up edge and extending tool life. The Form B chamfer eases the tap into the hole, reducing the risk of cross-threading and ensuring a smooth cutting action. With a 6H tolerance, it produces threads that meet strict standards for fit and interchangeability.

Ideal use cases

• Tapping through holes in steel, stainless steel, cast iron, and non-ferrous metals
• Production machining where consistent thread quality and long tool life are critical
• Applications requiring a standard DIN 376B tap with a reinforced shank

Good to know

Country of origin: Poland. The tap is supplied individually. For best results, use appropriate cutting fluid and ensure proper alignment in the machine.
