Designed for CNC and manual lathes, this positive stop adjustable blade handles grooving, parting off to centre and chamfering operations using GTN-3 self-lock inserts. Hardened alloy steel body with a positive stop and adjustable design; vernier scale marked in 32nds ensures repeatable offsets; includes extractor for easy insert removal; chipbreaker geometry on inserts supports high speeds and feed rates. Blade width: 0.120 in; height: 1.25 in; designed to suit self-lock cut-off holders for GTN-3 inserts; robust cross-section provides rigidity for consistent parting and grooving. Suitable for machining steels, stainless steels, cast iron, aluminium and other non-ferrous materials; multiple lead angles allow fine-tuned cutting geometry from facing to chamfering. Intended for machinists, toolroom operators and engineers seeking consistent cut-off performance; supplied as one blade without inserts; use with matching GTN-3 inserts and holder. Accusize Industrial Tools positive stop adjustable blade for self-lock cut-off inserts provides a dependable solution for grooving, parting off and chamfering operations on CNC and manual lathes. The blade's hardened alloy steel body features a positive stop and fine vernier scale for repeatable adjustments. Each blade uses self-lock GTN-3 inserts (ordered separately) and includes an extractor for simple insert removal; chipbreaker designs enable high cutting speeds and feed rates. This 2402-0014 model matches GTN-3 inserts with a blade width of 0.120 in and height of 1.25 in. It suits standard self-lock cut-off tool holders and machines steels, stainless steels, cast iron and non-ferrous metals. Multiple lead angles accommodate various cutting geometries, and the vernier marked in 32nds ensures precise offset. Designed for machinists and maintenance engineers seeking consistent cut-off performance.
