Kennametal 1096261 Indexable Turning Toolholder MDJNL205D

Product Description

The KENNAMETAL 1096261 is a left-hand indexable turning toolholder in the MDJN style, designed for use with DN-type negative-rake inserts held in place by a clamp and screw mechanism. Part of the Kennametal Kenloc series, it features a square steel shank measuring 1.25 inches wide by 1.25 inches tall and an overall length of 6 inches. The head length is 1.47 inches and the back-of-bar to cutting edge distance is 1.5 inches. This toolholder is sized for inserts with a 5/8-inch (0.625-inch) inscribed circle. Licensed machinists and CNC turning specialists use this style of holder for external turning operations on lathes and turning centers.

The MDJNL205D-style toolholder is suited for external turning applications on CNC lathes and manual turning centers in both production and job-shop environments. The left-hand orientation positions the insert for specific approach angles and chip direction requirements. The Kenloc clamping system provides secure, repeatable insert seating, making it a standard choice for shops running negative-rake DN-series inserts on medium to large diameter workpieces. No coolant-through capability is present in this model, so external flood or mist coolant is the appropriate delivery method for this holder.
