For continuous, high-velocity automated CNC operations on homogeneous steels, prioritize chemical vapor deposition (CVD-coated) hard carbide insert grades (ISO P10-P20). For variable manual setups, interrupted facing passes, or mixed-alloy machining runs, implement physical vapor deposition (PVD-coated) multi-layer micro-grain grades to maximize edge toughness and arrest thermal micro-cracking.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43420773941420,"sku":"SCACL2020K09","price":22.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND_SCACL2020K09_left_hand_external_indexable_lathe_turning_tool_holder_with_20mm_square_shank_for_ISO_CCMT_09T3_inserts..jpg?v=1779409065","url":"https:\/\/cnchome-beyond.com\/products\/beyond-scacl2020k09-left-hand-turning-toolholder","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
