Description

The Original Korloy WNMG080404-HM NC3030 (ANSI: WNMG 431-HM) is a specialized 80° Trigon Turning Insert engineered for Impact Resistance and Toughness. While maintaining the precision of a 0.4mm (1/64") radius, this insert utilizes the NC3030 CVD Grade, which is specifically formulated to prevent edge chipping during interrupted cutting or when machining workpieces with unstable setups. It is the ultimate insurance for steel turning operations that demand both high precision and extreme durability.

Built for the Tough Stuff: NC3030 is Korloy’s go-to grade for stability. If your NC3020 inserts are chipping due to vibrations or irregular part surfaces, switching to NC3030 will provide the structural integrity needed to finish the job without downtime.

Technical Specifications (ISO Metric vs. ANSI Inch):

ISO Designation WNMG 080404-HM
ANSI Designation WNMG 431-HM
Corner Radius (r) 0.4 mm / (1/64")
Grade NC3030 (High-Toughness CVD)
Chipbreaker HM (Medium / Universal)

Compatible Tool Holders:

For optimal rigidity in interrupted cuts, pair this insert with our heavy-duty holders:

Core Performance Benefits:

  • High Resistance to Chipping: The NC3030 substrate is significantly more ductile, absorbing shocks from interrupted cuts that would shatter harder grades.
  • Low Cutting Pressure: The R0.4 radius reduces radial forces, helping to prevent chatter on long-overhang boring bars or thin shafts.
  • Versatile HM Geometry: The Medium (HM) chipbreaker provides consistent chip evacuation across a broad range of steel alloys and cutting depths.
  • 6-Edge Economy: Like all WNMG inserts, this provides 6 usable edges, making it much more cost-efficient than 4-edge CNMG alternatives for high-volume production.

Recommended Cutting Parameters:

Machining Condition Cutting Speed (Vc) Feed Rate (fn) Max Depth (ap)
Interrupted Cut (Steel) 140 - 240 m/min 0.10 - 0.20 mm/rev 2.0 mm
Stable Cut (Steel) 180 - 280 m/min 0.10 - 0.25 mm/rev 2.0 mm

Packaging: 10 pieces per box.
