Part of the Kennametal Top Notch series, it accepts N-style inserts held in place by a clamp-style retention method for secure, repeatable edge positioning. The bar features a 1\/2-inch shank diameter and an overall length of 8 inches, allowing it to reach bores with a minimum diameter of 0.730 inches (18.54 mm). A built-in coolant-through passage with a 1\/16-27 NPT thread connection supports chip evacuation and tool life in deep-bore applications. Licensed machinists and toolroom technicians install this bar in production and job-shop environments where consistent bore geometry is required.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for light to medium internal turning work where left-hand cut geometry is required. The Top Notch series design positions the cutting edge at a 3-degree lead angle, which influences chip formation and surface finish in finish-bore passes. The center-to-cutting-edge dimension of 0.437 inches is useful for calculating bore clearances during setup. The coolant-through capability makes it a practical choice for harder materials or deeper bores where flood coolant alone does not adequately reach the cutting zone. It is a single-use toolholder configuration and is not designed as a multi-use convertible tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cut orientation for climb-boring and specific machine configurations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for rigid, repeatable N-style insert seating\u003c\/li\u003e\n  \u003cli\u003eCoolant-through port threaded 1\/16-27 NPT for internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003e0.730 inches (18.54 mm) minimum bore diameter supports tight-bore applications\u003c\/li\u003e\n  \u003cli\u003e3-degree lead angle geometry influences chip flow and cutting forces\u003c\/li\u003e\n  \u003cli\u003eTop Notch series platform with consistent insert indexing and changeover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with N-style (Top Notch) inserts. Compatible insert style is designated N. in the Kennametal Top Notch series. Specific compatible insert part numbers were not provided in the available product data; consult Kennametal tooling guides or the insert compatibility chart for this holder style.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machining technicians or toolroom professionals. Before mounting or indexing inserts, power down the machine and engage all axis locks per standard lockout\/tagout procedures. Use the appropriate Torx or hex key as specified by the insert clamp design when seating N-style inserts — do not overtighten by feel alone; refer to the Kennametal torque specification card for the clamp screw. Confirm shank-to-bore clearance and overhang length against your machine tool manufacturer guidelines before beginning cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.730 inches (18.54 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches (203.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Cut\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.
