Mechanically, it channels the cutting forces axially down the axis of the workpiece and lathe spindle. This makes it far superior for short, thick parts where you want to minimize radial push and cross-slide deflection.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bp-faq-item\"\u003e\n\u003cdiv class=\"bp-faq-q\"\u003eQ: Does the SCACR2525M12 hold CCMT 09 inserts?\u003c\/div\u003e\n\u003cdiv class=\"bp-faq-a\"\u003eA: No. The '12' at the end of the code explicitly states it is designed for size 12 inserts (CCMT 1204__ series, which features an inscribed circle of 12.7mm or 1\/2\"). For size 09 inserts, you must purchase the SCACR2525M09 variant.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"bp-faq-item\"\u003e\n\u003cdiv class=\"bp-faq-q\"\u003eQ: What causes premature insert corner chipping on this holder, and how do I troubleshoot it?\u003c\/div\u003e\n\u003cdiv class=\"bp-faq-a\"\u003eA: Corner chipping is usually caused by micro-vibration from a loose locking screw or cutting chip recutting. Ensure the insert pocket is completely clean of swarf before seating the insert and torque the M4.5 screw tightly. If machining gummy stainless steel, verify that your chipbreaker geometry has a sharp, positive rake angle to slice the chip instead of pushing it.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- 11.

For continuous, high-velocity CNC automated loops on alloy steels, prioritize chemical vapor deposition (CVD-coated) hard carbide insert grades (ISO P10-P20). For heavy manual setups, multi-piece shafts, or light interrupted profiling passes, select physical vapor deposition (PVD-coated) multi-layer micro-grain grades to maximize cutting edge toughness and prevent thermal cracking.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43420792750252,"sku":"SCACR2525M12","price":33.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND_SCACR2525M12_right_hand_external_turning_tool_holder_with_25mm_shank_for_ISO_CCMT_1204_carbide_cutting_inserts..jpg?v=1779408549","url":"https:\/\/cnchome-beyond.com\/products\/beyond-scacr2525m12-external-turning-toolholder","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
