Optimized for left-hand tool paths (SCKCL format), this solid alloy structural steel bar features a \u003cstrong\u003e16mm cylindrical clamping shank\u003c\/strong\u003e and a 180mm total reach length (Q-type dimension). By matching a compact 16mm shank body with an optimized size-09 insert pocket, this tool ensures an exceptional ratio of chip clearance room to bar rigidity, allowing smooth machining cycles inside bores down to a tight \u003cstrong\u003e20mm minimum diameter\u003c\/strong\u003e without experiencing tool rubbing or chip packing.\u003c\/p\u003e\n\u003cp\u003eBuilt with a 75-degree approach lead angle, the tool head effectively converts deflection forces from radial pushback into axial load pressure directed back down the lathe carriage centerline. When configured with premium 80-degree positive rhombic indexable inserts featuring specialized multi-stage chipbreaker geometries (such as \u003cstrong\u003eCCMT 09T304 \/ 09T308\u003c\/strong\u003e for medium steel semi-finishing or polished \u003cstrong\u003eCCGT 09T304\u003c\/strong\u003e for non-ferrous aluminum), swarf is curled into neat, tight fragments.
