Incorporating a robust \u003cstrong\u003e2525mm solid square shank matrix\u003c\/strong\u003e (equivalent to a standard 1.0\" x 1.0\" industrial block shank) with a 150mm overall length (M-type length standard), this tool holder balances structural rigidity with high versatility. Constructed from premium vacuum-quenched alloy tool steel hardened to HRC 42-45, its dense metallurgical core delivers immense structural deflection resistance, completely dampening chatter waves caused by severe cuts and high radial forces.\u003c\/p\u003e\n\u003cp\u003eThe distinctive technical advantage of the MVQNR holder is its \u003cstrong\u003e107.5-degree approach angle (lead angle)\u003c\/strong\u003e, which makes it uniquely optimized for back-turning (cutting toward the tailstock or pulling out of a shoulder) and deep plunge profiling. This geometric configuration is paired with our \u003cstrong\u003eM-Type Double-Clamping Mechanism\u003c\/strong\u003e, which combines a rugged top clamp and a central pull-back pin lock.

A standard 93° holder (like MVJNR) is optimized for cutting toward the chuck or tracing external contours down steps. The 107.5° approach angle of the MVQNR bar is uniquely swept back, which gives the tool crucial clearance when executing right-hand back-turning operations (cutting away from the spindle) and plunge profiling into deep angles. It allows the narrow 35° VNMG insert tip to enter and exit tight shoulder reliefs without the trailing edge of the steel body rubbing against the workpiece.\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: Why is the M-Type Double Clamping system critical for a 2525mm shank size?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA2: Mechanical load management and micro-displacement prevention. When performing back-turning or deep plunge profiling with a narrow 35° diamond VNMG insert, the cutting forces aren't just pushing down; they try to pivot and pull the insert out of its pocket. A single center screw can easily fail or cause insert flutter under heavy loads. The BEYOND M-Type system clamps down with a heavy-duty overhead steel bridge while simultaneously using an internal pin to pull the insert back into the pocket corner, ensuring total stability.\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: Can I use this MVQNR2525M16 holder for both roughing and finishing operations?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #444;\"\u003eA3: Yes, depending entirely on your chosen insert chipbreaker geometry and grade. The rigid alloy steel body provides a vibration-free baseline for micro-finishing cuts when paired with a sharp ground precision insert (like VNMG 160404 with a fine finishing chipbreaker). For medium-to-heavy roughing, pair it with a durable CVD grade insert (like VNMG 160412 with a roughing chipbreaker) to maximize chip evacuation and feed rates.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e9.
