DIJET WNMG080408-SF JC8015 PVD Coated Carbide Turning Insert with SF Chipbreaker and R0.8 Corner Radius for CNC Turning Carbide inserts

The WNMG080408-SF JC8015 is premium multilayer PVD-coated carbide indexable turning insert designed for precision semi-finish and finish OD & ID turning on CNC lathes. Featuring 80° hexagonal negative WNMG geometry, SF fine-finish dedicated chipbreaker and exclusive JC8015 fine-grain carbide grade, this insert delivers outstanding anti-adhesion property and balanced edge toughness to maintain stable cutting performance during continuous and mild interrupted finish turning of carbon steel and stainless steel components.

Optimized SF precision chip groove ensures orderly short chip curling and smooth chip evacuation, securing ultra-precise dimensional tolerance and superior surface finish for mass precision parts batch production.

• JC8015 fine-grain tungsten carbide substrate with high-temperature PVD coating possesses excellent wear resistance and anti-built-up-edge performance, ideal for medium-speed finish turning of carbon steel, alloy steel and austenitic stainless steel.
• Tailored SF fine machining chipbreaker breaks chips into short fragments effectively to eliminate tangled chips scratching finished workpiece surface.
• Standard WNMG0804 insert dimension with optimized clearance angle, easy clamping and fully compatible with matching WNMG series turning tool holders.
• Precision ground sharp cutting edge greatly improves finished surface quality and minimizes post-processing deburring operations.
• Subtle edge honing enhances edge stability to avoid micro-chipping during long continuous finish cutting and prolong insert service life.

• Carbon steel
• Alloy structural steel
• Austenitic stainless steel
• Pre-hardened low-hardness steel
• Cast steel

• Precision outer diameter semi-finish & finish turning
• CNC lathe fine boring inner hole processing
• Light interrupted contour finish turning
• Automotive precision component batch machining
• Universal high-surface-requirement turning

Combining stable JC8015 coated carbide substrate and professional SF finish-type chipbreaker design, the WNMG080408-SF maintains consistent cutting stability and high dimensional accuracy during precision steel and stainless steel turning. Its superior finish machining performance reduces secondary polishing workload and improves workshop overall production efficiency, becoming an economical dedicated insert for mass precision finish turning production.
