Grade: CT3000 (cermet) — designed for turning/grooving/parting of alloy steels & stainless steels, featuring high wear resistance and low coefficient of friction. -
Geometry: Negative 80° rhombic (CNMG-MT family) for robust medium‐rough turning applications of steel, cast iron & stainless steel.
-
Cutting edge material/coating: Cermet body with “cermet” grade/coating in CT3000 – enabling excellent surface quality and tool-life performance.
-
Application materials: Steel, stainless steel, cast iron (see CT3000 ISO ranges: P/M/K groups)
-
Typical specs: Insert thickness S = 4.76 mm, Corner Radius RE = 0.4 mm, Depth of Cut (apmx) up to ~5 mm, Feed range ~0.15-0.40 mm/rev quoted for this insert.
Why It’s a Best Seller
-
Less downtime: With the CT3000 cermet grade applied to this geometry, you get longer edge life versus standard carbide in many medium finishing/medium roughing operations — fewer insert changes, fewer interruptions.
-
Better surface finish: The low friction, high wear-resistance of the CT3000 grade means cleaner surface on steel/stainless/cast iron, helping you hit tighter tolerances with fewer passes.
-
High wear resistance: For turning steels and cast irons where wear can ruin productivity, this insert holds up — the combination of CNMG MT geometry + CT3000 gives robust durability.
-
Cost-per-component advantage: By extending tool life and maintaining consistent quality, each component costs you less — ideal for high-volume or repeat operations.
