Built to support standard 60-degree positive triangle inserts (\u003cstrong\u003eTCMT 110204 \/ TCGT 110202\u003c\/strong\u003e), this tool shank features optimized rake vectors that enhance chipbreaker performance. When paired with high-performance carbide matrices, the geometric pocket angle forces immediate spiral swarf deformation, preventing continuous stringy nesting and maximizing heat dissipation away from the workpiece. It delivers exceptional stability and superior surface roughness during light finishing to medium semi-roughing cut routines on carbon steel, alloy steel, high-temp stainless steel, and non-ferrous metals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 40px;\"\u003e\n\u003ch2 style=\"font-size: 20px; color: #47479f; border-bottom: 2px solid #47479F; padding-bottom: 8px; margin-bottom: 20px; font-weight: bold;\"\u003e2.
