FANAR tap M16 DIN 376C R45 (6H) HSSE-PM S-TiCN S-NC

The FANAR tap M16 DIN 376C R45 (6H) HSSE-PM S-TiCN S-NC is a solid high-speed steel with powder metallurgy (HSSE-PM) cutting tool designed for producing internal metric threads with a nominal size of M16. It conforms to the DIN 376C standard and features an R45 chamfer for robust entry and a 6H tolerance class for accurate fit. The S-TiCN coating improves wear resistance and tool life, making the tap suitable for repeated use in production and maintenance environments on compatible materials.

Advantages

The HSSE-PM substrate provides a balanced combination of toughness and hardness for reliable performance in both manual and CNC tapping operations. The S-TiCN coating reduces friction and increases resistance to abrasive wear, which helps maintain dimensional accuracy over longer cycles. Conformance to DIN 376C and the 6H tolerance class ensures interchangeable threads and predictable assembly behavior.

Suitable for

• Cutting internal metric threads M16 in steel and general engineering materials
• CNC tapping cycles where repeatability and tool life are required
• Manual tapping in maintenance and repair tasks with pre-drilled holes
• Production runs requiring DIN 376C thread form and 6H tolerance

When it may not be suitable

This tap is not intended for use in materials that require specialized geometries or coatings not offered here, such as highly abrasive composites or non-ferrous metals where different coatings perform better. It may not be optimal for interrupted cuts or heavily contaminated holes without appropriate coolant and chip evacuation.

Key specifications

• Thread size: M16
• Thread standard: DIN 376C
• Chamfer type: R45 (long chamfer)
• Tolerance class: 6H
• Material of tool: HSSE-PM (high-speed steel, powder metallurgy)
• Coating: S-TiCN (titanium carbonitride)
• Application: internal thread cutting, CNC and manual tapping

How to use

Select the correct drill size for the M16 thread according to DIN recommendations and ensure the hole is properly aligned and deburred. Use appropriate cutting fluid for the work material and set the tapping speed and feed compatible with the machine or hand tapping method. For CNC operations, use a rigid holder and program conservative feeds on the first pass; for manual tapping, apply steady, even pressure and reverse periodically to break chips. After tapping, inspect the thread for conformity to the 6H tolerance and clean chips and coolant residues from the thread.

What to consider before purchase

• Verify the workpiece material compatibility with HSSE-PM and S-TiCN coating
• Confirm required thread standard (DIN 376C) and tolerance (6H) for mating parts
• Ensure correct hole diameter and machine capability for M16 tapping
• Plan for suitable coolant and chip evacuation for the chosen machining process

Usage recommendations

Use with adequate coolant and controlled feed rates for best tool life; inspect threads with proper gauges to confirm 6H conformity. Replace the tap when wear affects thread accuracy or chip evacuation becomes inconsistent.
