Featuring a standard \u003cstrong\u003e25x25mm solid square steel shank\u003c\/strong\u003e (the cross-section equivalent to an international 1.0\" x 1.0\" \/ 1 inch block shank) with a robust 150mm overall body length (M-type length standard), this tool holder delivers exceptional structural dampening and maximum stiffness under aggressive heavy-roughing conditions. Forged from high-alloy vacuum-quenched tool steel and heat-treated to HRC 42-45, its metallurgical architecture eliminates high-frequency chatter harmonics and radial deflection under maximum depth-of-cut (ap) loads.\u003c\/p\u003e\n\u003cp\u003eThe geometric advantage of the MTGNR profile lies in its \u003cstrong\u003e91-degree approach angle (lead angle)\u003c\/strong\u003e. This configuration directs the vast majority of extreme cutting forces axially straight down the 25x25mm shank body into the lathe turret block, reducing radial push-away tendencies when tackling high metal removal volume (MRR). It allows large 60° triangular negative inserts (such as \u003cstrong\u003eTNMG 220408 \/ TNMG 220412 \/ TNMG 220416\u003c\/strong\u003e) to transition smoothly across heavy longitudinal turning runs without trailing edge drag. Utilizing our industry-proven \u003cstrong\u003eM-Type Double-Clamping System\u003c\/strong\u003e—combining an overhead bridge clamp with a central internal pull-back pin—this mechanism pulls the double-sided negative insert firmly onto a hardened carbide anvil shim and tight into the pocket walls. This layout completely prevents insert micro-displacement under severe mechanical shock loads, heavy feeds, and interrupted cuts.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 20px; margin: 25px 0; background-color: #fbfbfe;\"\u003e\n\u003ch3 style=\"margin-top: 0; color: #47479f; font-size: 16px; border-bottom: 1px solid #e0e0e0; padding-bottom: 8px;\"\u003eModel Nomenclature Decoder: MTGNR2525M22 (ISO \/ International Standard Chart Compliant)\u003c\/h3\u003e\n\u003cdiv style=\"margin-top: 12px; font-family: monospace; font-size: 13px;\"\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eM\u003c\/strong\u003e - \u003cstrong\u003eTop Clamp \u0026amp; Pin Lock System\u003c\/strong\u003e (Dual-action mechanism ensuring ultimate structural stability for heavy volumetric roughing)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; font-weight: bold;\"\u003e\n\u003cstrong\u003eT\u003c\/strong\u003e - \u003cstrong\u003e60° Triangular Insert Shape\u003c\/strong\u003e (Accommodates standard, highly economical 6-edged negative TNMG inserts)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eG\u003c\/strong\u003e - \u003cstrong\u003e91° Tool Approach Angle Geometry\u003c\/strong\u003e (Engineered for heavy longitudinal turning with minimal axial forces)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; font-weight: bold;\"\u003e\n\u003cstrong\u003eN\u003c\/strong\u003e - Negative Turning Insert Profile (0° clearance angle with double-sided cutting edges for maximum cost optimization)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eR\u003c\/strong\u003e - Right-Hand Tool Cutting Direction (Clockwise machining orientation tracking on heavy CNC turrets)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003e2525\u003c\/strong\u003e - \u003cstrong\u003e25mm x 25mm Standard Square Shank Cross-Section\u003c\/strong\u003e (Exact 1.0\" x 1.0\" Imperial equivalent sizing, built for standard lathe turret blocks)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eM\u003c\/strong\u003e - 150mm Standard Tool Length (Mid-size length configuration providing optimized clearance and secure clamping layout)\u003c\/div\u003e\n\u003cdiv style=\"display: block; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003e22\u003c\/strong\u003e - Accommodates 22mm Cutting Edge Length Inserts (Precision pocket matched for international standard heavy-duty TNMG 2204--)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 15px; margin-bottom: 25px; background-color: #47479f; color: #ffffff; text-align: center;\"\u003e\n\u003cp style=\"margin: 0 0 10px 0; font-weight: bold; font-size: 16px;\"\u003eOperating left-hand tool setups or requiring a larger 3232mm shank profile for increased heavy-duty machining?\u003c\/p\u003e\n\u003cspan style=\"color: #47479f;\"\u003e\u003cspan style=\"display: inline-block; background-color: rgb(255, 255, 255); padding: 8px 20px; border-radius: 4px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cb\u003e \u003ca href=\"https:\/\/cnchome-beyond.com\/search?q=tnmg220404\" target=\"_blank\" rel=\"noopener\"\u003eView the Industrial MTGNL2525M22 Tool Holder (25x25mm Shank, Left-Hand) → \u003c\/a\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e2.

Standard 25mm shanks often accept thinner TNMG 1604 inserts. The MTGNR2525M22 allows standard lathe users to upgrade to heavy international standard TNMG 2204 inserts, unlocking a much more robust carbide thickness (4.76mm) and massive cutting edge that easily survives deep, heavy volumetric roughing cycles.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px; padding: 12px; background-color: #f9f9f9; border-radius: 4px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ2: What is the benefit of the MTGNR 91° approach angle over an MTJNR 93° angle for roughing runs?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA2: Radial force reduction. The 91° approach angle directs the vast majority of extreme cutting forces axially straight down the 25x25mm shank body into the lathe turret. This layout minimizes radial deflection and push-away tendencies, which is critical for maintaining strict tolerances on long forged shafts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px; padding: 12px; background-color: #f9f9f9; border-radius: 4px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ3: How does the M-type clamping system compare to simple screw-down style locks on a 25mm bar?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA3: The M-type mechanism uses a top bridge clamp and a pin lock simultaneously to pull the negative insert backward and downward into the pocket.
