FANAR závitník M16 DIN-376C R40 (6H) HSSE TIN 800X

Threading tap engineered for M16 metric threads, built to DIN 376C with an R40 spiral flute geometry and a 6H tolerance class. The TiN-coated HSSE substrate delivers high-speed performance and extended tool life in tough materials, making it a dependable choice for production environments where precision and durability are critical.

Advantages

The TiN (titanium nitride) coating reduces friction and heat buildup, allowing faster cutting speeds and preventing chip welding. The HSSE (high-speed steel with cobalt) base provides excellent hot hardness and wear resistance, ideal for stainless steels and high-strength alloys. The R40 spiral flute design efficiently evacuates chips upward, preventing clogging in blind holes and ensuring clean thread profiles. The 6H tolerance guarantees a standard fit for metric fasteners, reducing the risk of over- or under-tapping.

Suitable for

• Blind hole tapping in stainless steel, alloy steel, and other difficult-to-machine materials
• CNC machining centers and high-speed tapping operations
• Maintenance and repair work requiring precise M16 threads
• Production lines where consistent thread quality and long tool life are essential

Key specifications

• Thread size: M16
• Standard: DIN 376C
• Flute type: R40 spiral
• Tolerance class: 6H
• Material: HSSE (high-speed steel with cobalt)
