It accepts CP-B1208D inserts with a compatible insert size code of 1208 and features a negative rake angle of -4 degrees, suited for stable, high-force turning operations. The shank measures 0.75 inches wide by 0.75 inches tall. With coolant-through capability and a steel toolholder body, this holder is built for production turning environments where thermal management and insert seat rigidity are priorities. It is installed by machinists and CNC turning center operators in job shop and production settings.\u003c\/p\u003e\u003cp\u003eThis toolholder fits CNC lathes and turning centers configured for the CoroTurn Prime quick-change system. It is designed for external turning applications and is suitable for both production and contract machining environments requiring consistent insert indexing and repeatable tool offsets. The right-hand cutting direction and negative rake geometry make it appropriate for roughing and semi-finishing passes on a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClamp-style insert holding for secure seating under interrupted and heavy cuts\u003c\/li\u003e\n\u003cli\u003eCoolant-through capability directs cutting fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eNegative rake angle (-4 degrees) supports strong insert edges for demanding turning operations\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body provides rigidity and durability in production use\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with 0.75 inch square shank for standard toolpost and turret mounting\u003c\/li\u003e\n\u003cli\u003eCompatible insert size code 1208 with CP-B1208D insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CP-B1208D inserts (insert size code 1208, 12.00 mm inscribed circle, 0.2362 inch thickness).
