16ERM14W IC908 PVD Coated Carbide External Threading Insert for 14TPI Whitworth CNC Turning with High Wear Resistance

The 16ERM14W IC908 is premium PVD-coated carbide external threading insert manufactured by ISCAR for CNC inch outer thread turning. Adopting standard full-profile 55° Whitworth 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 14 TPI Whitworth 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 55° Whitworth thread profile customized exclusively for 14TPI standard imperial 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.
