The Kennametal A24-MCLNR5 is a right-hand indexable boring bar with a 1-1/2 in (38.10 mm) round steel shank and a 14.00 in (355.60 mm) overall length, designed for internal turning on CNC and manual lathes. The MCLNR designation decodes as: M = shank style (cylindrical), C = insert clamping method (screw and clamp/top clamp), L = insert shape (CN.. — 80° diamond/rhombic), N = insert clearance (0° normal), R = hand of cut (right hand), and 5 = insert IC size (5/8 in / 15.875 mm IC for CN..-5__ inserts); the A24 prefix indicates a 1-1/2 in (24/16 in) shank diameter in the Kennametal boring bar series. The -5.000° lead angle (MCLNR geometry) directs cutting forces axially, reducing radial deflection and improving bore geometry in steel and cast iron at moderate to aggressive depths of cut. Compatible inserts are CN.. (CNMG/CNMA) style in size 5 (5/8 in IC), with the minimum bore diameter of 44.70 mm (1.760 in) defining the smallest bore this bar can address. This bar is offered in new — other condition, meaning it is an unused or surplus unit that may show minor cosmetic marks consistent with storage or handling, but is functionally new.
