chipbreakerFor cut-off operations with max. diameter up to .630"| Swiss CNC lathes
Tightly curls chips to prevent tangling
CX molded chipbreaker curls and controls chips. Prevents damage to machined surface by directing chips away from the part surface
Eliminates cutting edge chipping during cut-off operations.
Ideal for stainless steel materials with high nickel content (304SS, 316SS, and 630SS)

CX chipbreaker DM4 CTPA15FRN-CX |
5,000 pcs / corner |
Competitor's wiper insert | 2,000 pcs / corner |
Competitor's insert edge chipped resulting in a rough machined surface.
The CX insert maintained a good cutting edge resulting in stable machining, smooth machined surface, and long tool life.

CX chipbreaker ST4 CTP15FLN-CX |
3,500 pcs / corner |
Competitor's molded chipbreaker (PVD coated carbide) |
2,000 pcs / corner |
The CX chipbreaker achieved stable machining and controlled the chip and evacuated it away from the part.
The ST4 grade is best for stainless steel materials which extended tool life by 1.5 times compared to the competitor's insert.
