The Kennametal MDJNR163C is a new, right-hand external turning toolholder from the KL Series, designed to accept 55° diamond (DNMG) negative-rake inserts with a side-lock (pin-lock) clamping system. Decoding the ISO designation: M = side-lock clamping method, D = 55° diamond insert shape, J = 3° clearance angle (negative rake), N = negative rake, R = right-hand cutting direction, 163 = 1 in × 1 in (16/16) shank cross-section with 3 in overhang length (style C body), C = shank style. The holder is manufactured in the USA from alloy tool steel with a black oxide finish, providing corrosion resistance and a precision-ground insert pocket that ensures accurate, repeatable insert seating for OD turning, profiling, and chamfering operations on CNC lathes and manual engine lathes. The Kennametal catalog/internal part number is 1096242 as visible on the packaging label, and the holder is shipped in its original factory packaging.
