Featuring a massive \u003cstrong\u003e32x32mm solid square alloy steel shank\u003c\/strong\u003e (the exact cross-sectional equivalent to an international 1.25\" x 1.25\" \/ 1-1\/4 inch standard block shank) with an extended 170mm overall body length (P-type length standard), this turning bar provides extreme rigid support to completely suppress structural chatter during large-scale metal cutting operations. Forged from high-tensile structural alloy steel and vacuum heat-treated to HRC 42-45, its optimized metallurgical architecture effectively minimizes micro-harmonics and radial deflection under intense mechanical stress.\u003c\/p\u003e\n\u003cp\u003eThe unique engineering advantage of the MTFNL3232P16 profile lies in its pairing of an ultra-rigid 32mm square body with highly economical \u003cstrong\u003eTNMG 1604--\u003c\/strong\u003e inserts. Its signature \u003cstrong\u003e91-degree approach angle (lead angle)\u003c\/strong\u003e allows large 60° triangular negative inserts (such as \u003cstrong\u003eTNMG 160404 \/ TNMG 160408 \/ TNMG 160412\u003c\/strong\u003e) to transition smoothly across heavy facing, crust scaling, and deep longitudinal roughing paths with minimal radial pushback. Utilizing our industry-proven \u003cstrong\u003eM-Type Double-Clamping System\u003c\/strong\u003e—which coordinates an overhead bridge clamp with a central internal pull-back pin—this assembly forces the double-sided negative insert firmly onto a hardened carbide anvil shim and tight into the pocket walls.
