FANAR KIERREAPPI M12 DIN-376B (6H) HSSE HL INOX

The FANAR TAP M12 DIN-376B (6H) HSSE HL INOX is a high-performance machine tap specifically designed for threading stainless steel (INOX). Manufactured from premium HSSE-PM (High-Speed Steel with Cobalt, Powder Metallurgy), this tap offers exceptional wear resistance and longevity. It conforms to DIN 376B standard with a Form B chamfer (4-5 thread lead), making it ideal for through-hole applications. The helical flute geometry is optimized for efficient chip evacuation in stainless steel, while the reinforced shank provides stability during high-speed operations.

Advantages

This tap delivers precise metric coarse threads (M12 x 1.75 mm) with a 6H tolerance class, ensuring a perfect fit for standard nuts and bolts. The HSSE-PM material provides superior hardness and heat resistance, reducing tool breakage and extending service life. The helical flute design minimizes cutting forces and improves surface finish, even in tough INOX materials.

Suitable for

• Threading through holes in stainless steel (INOX) workpieces
• Industrial manufacturing, automotive, and aerospace applications
• Use with machine tools, CNC machines, or tapping machines
