PLEASE NOTE: these are
NOT counterfeit inserts. These were purchased in a large lot from a
local industrial auction at a huge manufacturing plant. I have been
burned by counterfeit ebay inserts before; I know what it's like.
Items exactly as shown in pictures and are all new and unused. If for some reason I accidentally include a used insert or miscount the quantity, I will issue a partial refund with no questions asked.
Qty 5 Kennametal DPMT 2151 21.51 DPMT2151LF 63492546475 DPMT070204LF KC935 carbide insert.
DPMT is essentially the same as a DCMT but with a more positive rake. Can be helpful in some machining situations, especially with softer materials.
KC935 grade description:
Composition: A multilayered coating with optimized layer thickness over a
cobalt-enriched substrate. Application: Grade KC935 is fast becoming
the favorite grade for soft and gummy workpiece materials. Successfully
apply on most steels, ferritic, martensitic, and austenitic stainless
steels, and heavier cutting in nickel base alloys. The TiCN/TiC coating
layers are effective at low to medium speeds, and the outer alumina
coating maintains hot hardness at medium to high speeds. The well
balanced substrate maintains toughness and edge strength. The specially
engineered coating surface provides a smooth, stable cutting edge that
resists build-up and microchipping. If you like grade KC850, try grade
KC935, and bring real flexibility to your metalcutting operations.
