TCT is rewriting the book on CBN

With both solid and tipped versions available as standard, we’ve got every application covered — from roughing and semi-finishing to high-precision finishing operations. Discover the CBN series that’s changing the game in both cost-per-piece and productivity.

TCT-SBN-550 & TCT-SBN-570

TCT’s proprietary SBN CBN line is engineered for results, not comparisons. Built from the ground up for strength, speed, and stability, our blends combine advanced materials technology with proven edge-preparation expertise to deliver consistent, repeatable performance across the toughest production environments.

TCT-SBN-570 — High-Content CBN for Cast Irons & HRSA Materials

TCT-SBN-570 is a high-content CBN grade developed for finishing cast irons and heat-resistant superalloys (HRSAs). Designed to thrive under high heat and pressure, this grade delivers superior wear resistance, tool life, and surface integrity when machining demanding materials. When precision, stability, and endurance matter — SBN-570 delivers.

TCT-SBN-550 — Low-Content CBN for Hardened Steels & Ductile Irons

TCT-SBN-550 is a low-content CBN grade optimized for finishing hardened steels and ductile irons. Engineered for performance and economy, it provides exceptional surface finish, tool life, and cost-per-part savings — making it the go-to solution for high-volume finishing applications where reliability and repeatability drive profitability.

Both TCT-SBN-570 and TCT-SBN-550 represent the next generation of cutting performance — delivering exceptional hardness, thermal stability, and wear resistance across a wide range of materials.

By pairing material science with precision edge geometry, TCT continues to push what CBN can achieve — not just in tool life, but in total productivity and return on investment.
