16ERM3.00ISO IC908 PVD Coated Carbide Threading Insert for 3.0mm ISO Pitch External CNC Thread Machining

The 16ERM3.00ISO IC908 is premium PVD-coated carbide external threading insert manufactured by ISCAR for CNC metric outer thread turning. Adopting standard full-profile 60° ISO thread geometry and ISCAR exclusive submicron IC908 carbide grade, this insert features excellent toughness, reliable wear and chipping resistance to retain stable cutting performance in continuous and interrupted threading operations.

Specially designed for fixed 3.0mm pitch metric thread machining, it ensures precise thread contour formation, controllable chip evacuation and prolonged service life for mass-production external threading on general CNC lathes and automatic turning equipment.

• IC908 submicron carbide substrate with TiAlN PVD coating balances high toughness and abrasion resistance, well suited for high-temperature cutting of stainless steel and alloyed metal materials.
• Fixed full 60° ISO thread profile customized exclusively for 3.0mm pitch standard metric external threads to guarantee consistent thread dimensional precision.
• Standard 16ER external insert structure with optimized clearance, easy clamping and stable installation on matching 16ER-series external threading tool holders.
• Precision-ground cutting edge delivers superior thread surface finish and effectively lowers burr generation after machining.
• Reinforced cutting edge inhibits built-up edge accumulation during long-cycle continuous production and extends overall insert service lifespan.

• Carbon steel
• Alloy steel
• Austenitic stainless steel
• Heat-resistant superalloy
• Pre-hardened structural steel

• Standard 3.0mm pitch metric external thread turning
