FANAR cutting insert WYGNIATAK M 5 DIN-371C HSSE-PM WGN TiN without coolant holes

FANAR cutting insert WYGNIATAK M 5 DIN-371C HSSE-PM WGN TiN without coolant holes is a solid high-speed steel (HSSE-PM) turning insert with a thin titanium nitride (TiN) coating. It uses DIN-371C geometry in WGN style and size M 5, supplied without coolant holes for applications where through-tool coolant is not required. The insert is intended for general-purpose external and internal turning on medium-duty steel workpieces and is produced by FANAR with consistent dimensions for indexable tooling systems.

Advantages

The HSSE-PM substrate provides improved wear resistance and toughness compared to conventional high-speed steels, while the TiN coating reduces friction and extends cutting edge life in many turning operations. DIN-371C geometry ensures predictable chip formation and stable cutting performance in general turning tasks. The absence of coolant holes simplifies mounting and is suitable for setups using external or flood coolant or dry machining methods.

Suitable for

• External turning of medium-duty steel workpieces
• Internal turning and boring where WGN geometry is preferred
• Operations without through-tool coolant or with external/flood coolant
• General-purpose machining in workshops and production lines

Key specifications

• Material: HSSE-PM (high-speed steel, powder metallurgy)
• Coating: TiN (titanium nitride)
• Geometry: DIN-371C, WGN style
• Size: M 5
• Coolant holes: none (solid insert)
• Application: turning (external and internal)

How to use

Install the FANAR WYGNIATAK M 5 insert into a compatible indexable turning holder sized for DIN-371C/WGN inserts, ensuring proper seating and clamp torque according to the holder manufacturer's instructions. Select cutting parameters (cutting speed, feed, depth of cut) appropriate for medium-duty steels and the HSSE-PM substrate—moderate cutting speeds and conservative feeds help maximize life. Use external or flood coolant where required; avoid relying on through-tool coolant since the insert has no coolant holes.

Usage recommendations

For stable chip control and extended tool life, start with manufacturer-recommended cutting speed for HSSE-PM on medium carbon steel and adjust feed and depth of cut based on workpiece rigidity. Inspect the seating surface and clamp for secure retention at each index change. Use TiN-coated inserts for light to moderate interrupted cuts and applications where reduced friction is beneficial.
