Inject efficiency revolution into precision turning — the DCMT11T304-UM 1125 turning insert from Coromant, a core member of the CoroTurn® 107 series, stands as a performance benchmark in the metalworking industry with its exceptional material technology and innovative design. Whether for semi-finishing of steel, stainless steel, or superalloys, this industrial-grade insert delivers stable cutting performance and extended tool life, reducing costs and increasing efficiency for your production line.

• Dual-layer Wear-resistant Coating: Adopting TiAlN+TiAlN PVD coating technology, it's like wearing "double protective armor" for the insert. With a hardness of HRA 89-93, it significantly improves wear and high-temperature resistance, extending service life by over 30% compared to ordinary coatings.

• Cemented Carbide Substrate: High-strength cemented carbide body ensures stability during cutting. Even when processing workpieces with hardness up to 200HB, it maintains edge sharpness, reducing downtime from frequent tool changes.

• UM Chip Breaker Design: Optimized chip-breaking structure for multi-material processing effectively controls chip flow and avoids tool wrapping risks, especially suitable for pre-machining scenarios requiring surface finish.

• 55° Diamond Edge: Neutral cutting direction design with 7° major clearance angle provides excellent accessibility in narrow space machining, ideal for internal hole boring and complex surface turning.

Each box contains 10 inserts, supporting batch production needs. Compliant with international quality standards, it is the first choice for professional manufacturers pursuing high efficiency and low cost.
