FANAR WYGNIATAK M 2,5 DIN-371C (6HX) SR HSSE-PM WGN TIN — rotary cutting tool, 2.5 mm, DIN-371C

FANAR WYGNIATAK M 2,5 DIN-371C (6HX) SR HSSE-PM WGN TIN is a rotary reaming/finishing tool with a 2.5 mm cutting diameter manufactured to DIN-371C dimensions. Constructed from high-speed steel with powder metallurgy (HSSE-PM) and finished with a titanium nitride (TiN) coating, this tool features six cutting edges for controlled chip removal and improved surface quality. It is intended for precision metalworking operations where tolerance and surface finish are important, and is compatible with standard toolholders and drilling rigs that accept DIN-371C shank geometry.

Advantages

The HSSE-PM substrate offers enhanced toughness and wear resistance compared to conventional high-speed steels, while the TiN coating reduces friction and extends tool life in intermittent and continuous cutting. Six cutting edges provide smoother cutting action and lower vibration, helping to achieve consistent hole size and improved surface finish. Compliance with DIN-371C dimensions ensures interchangeability with existing toolholders and fixtures.

Suitable for

• Precision reaming and hole finishing in steel and alloy materials
• Use in milling or drilling cells requiring DIN-371C compatibility
• Applications needing fine surface finish and accurate hole tolerances
• Small-diameter machining tasks where tool rigidity and repeatability matter

Key specifications

• Cutting diameter: 2.5 mm
• Geometry: six cutting edges (6HX)
• Material: HSSE-PM (high-speed steel, powder metallurgy)
• Coating: titanium nitride (TiN)
• Shank/profile: manufactured to DIN-371C dimensional standard
• Application type: rotary reaming/finishing tool

How to use

Install the rotary tool in a compatible collet or toolholder that supports DIN-371C geometry and ensure secure clamping without runout. Select appropriate spindle speed and feed rate based on the workpiece material—lower speeds and moderate feeds for harder steels, higher speeds for softer alloys—while monitoring coolant application. Use steady, axial feed with minimal dwell at the hole entry and exit to preserve edge life and achieve consistent hole diameter. Inspect the tool periodically for wear or coating damage and replace when finish or tolerance degrades.

Usage recommendations

For best results, use cutting fluid appropriate to the machined material to reduce heat and improve chip evacuation. When machining hardened or abrasive materials, reduce cutting speed and consider intermittent pecking or reduced depth passes to limit thermal and mechanical stress on the HSSE-PM substrate.
