Featuring a specialized 93-degree cutting edge approach angle, this left-hand tool body directs cutting forces axially along the shank center line, which drastically minimizes radial deflection and harmonics during long-reach cycles. Optimized for standard 55-degree diamond profiles like \u003cstrong\u003eDCMT 070202 \/ DCMT 070204 (Metric)\u003c\/strong\u003e or \u003cstrong\u003eDCMT 21.51 \/ DCMT 21.52 (Imperial)\u003c\/strong\u003e, this holder interfaces flawlessly with advanced molded chipbreaker channels. This configuration ensures that continuous metallic swarf undergoes optimal structural deformation, inducing immediate helical chip fracture and flawless chip evacuation through tight internal bores, entirely preventing surface scratching and bird-nesting during precision fine-finishing and medium-roughing routines on carbon steel, alloy steel, stainless steel, and non-ferrous bars.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 2.

For this 10mm bar, that equals a maximum stable reach of 30mm. Extending the bar beyond this threshold increases elastic deflection and causes severe surface finish chatter.
