Built from steel with a 1.0-inch shank diameter and a 12-inch overall length, this bar accepts WN-style inserts held by screw or clamp and features a through-coolant port for continuous chip evacuation and thermal control at the cutting zone. The negative rake geometry and -5 degree lead angle suit medium to heavy interrupted and continuous cuts in steel, cast iron, and similar ferrous workpiece materials. Machinists and tool-and-die professionals rely on this style of bar where rigidity and repeatable insert indexing are critical to bore tolerance.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for production and job-shop environments where precise internal diameter work is required. The 1.2-inch minimum bore diameter and 12-inch OAL make it appropriate for deep-bore applications on parts with sufficient clearance for the 1.0-inch shank. The through-coolant design, fed via a 1\/4-18 NPT inlet, supports high-speed machining cycles where flood coolant alone cannot reach the cutting edge. This bar is a single-purpose toolholder and is not configured for multi-use applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.2-inch minimum bore diameter for medium-to-large internal turning work\u003c\/li\u003e\n\u003cli\u003e12-inch overall length supports deep-bore reach with a rigid 1.0-inch steel shank\u003c\/li\u003e\n\u003cli\u003eThrough-coolant via 1\/4-18 NPT port for effective chip flushing and heat management\u003c\/li\u003e\n\u003cli\u003eAccepts WN-style indexable inserts, 3\/8-inch inscribed circle, 3\/16-inch thickness\u003c\/li\u003e\n\u003cli\u003eNegative rake at -5 degree lead angle for stable cutting action on ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew or clamp insert holding method for secure, repeatable edge positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with WN-style indexable inserts with a 3\/8-inch inscribed circle and 3\/16-inch thickness, following A-MWLN toolholder conventions.

Ensure the machine spindle and coolant supply are fully de-energized and depressurized before mounting or removing the boring bar. Confirm the coolant port thread is compatible with the machine coolant fitting before connecting the 1\/4-18 NPT line.
