Built to the Top Notch Profiling Boring Bar series, this right-hand holder features a 3\/4 inch shank diameter, a 10 inch overall length, and a minimum hole diameter of 0.98 inches. The carbide body and clamp-style insert holding method provide rigid support during interrupted cuts and continuous profiling passes. It accepts NP.. 51L series inserts with a 5\/8 inch inscribed circle and delivers a neutral rake angle with a 5-degree lead angle for controlled chip flow and consistent surface finish in internal profiles.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for internal turning and profiling applications in production and job-shop environments. The 10 inch OAL allows reach into deeper bores while the 0.98 inch minimum hole diameter keeps it practical for medium-bore work. Coolant-through capability, with a coolant hole diameter of 0.281 inches, supports high-speed machining of steels, stainless alloys, and cast materials where heat and chip evacuation are critical concerns. Installation and tool changes are handled by machinists and CNC operators in machine shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal right-hand configuration for bore profiling and turning on CNC lathes\u003c\/li\u003e\n  \u003cli\u003eCarbide toolholder body for rigidity and vibration damping in deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 0.281 inch coolant hole diameter for effective chip and heat management\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention accepts NP.. 51L inserts with 5\/8 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eNeutral rake, 5-degree lead angle geometry for controlled cutting forces and consistent finish\u003c\/li\u003e\n  \u003cli\u003eE-NKLC toolholder style with center-to-cutting-edge measurement of 0.562 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with NP.. 51L series inserts.
