It uses a clamp and screw insert holding method with a negative rake geometry, providing rigid, repeatable insert seating during external turning operations. The shank measures 3\/4 inches wide by 3\/4 inches tall with an overall length of 4.5 inches. The toolholder accepts DN-style inserts with a 3\/8 inch inscribed circle. The steel construction is suited to production turning environments where consistent tool life and dimensional accuracy are critical. Installation and setup are typically handled by machinists or tool-room technicians.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is configured for right-hand cutting operations and is appropriate for use in external turning applications on lathes and turning centers. It fits standard square-shank tool stations in a wide range of machine tool turrets. The Kenloc clamping system is a Kennametal-proprietary design intended to minimize insert movement and maintain accurate edge positioning across multiple insert changes. Coolant-through capability is not available on this holder. It is sold as an individual unit and is a direct catalog item within the Kennametal standard line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMDJNR123B toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eKenloc clamp and screw insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry compatible with DN-style inserts (3\/8 inch inscribed circle)\u003c\/li\u003e\n  \u003cli\u003e3\/4 x 3\/4 inch square shank fits standard turret tool stations\u003c\/li\u003e\n  \u003cli\u003eOverall length of 4.5 inches with 1.25 inch head length\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body for rigidity in production turning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept DN-style inserts with a complete insert compatibility designation of DN.. 332 and a 3\/8 inch inscribed circle.

Power down and lock out the turning center spindle before mounting or removing the toolholder from the turret station. Ensure the shank seating surfaces and turret pocket are clean and free of chips before clamping.
