It features a 0.75 x 0.75 inch square shank and an overall length of 4.5 inches, built to accept DN-style negative-rake inserts held in place by a clamp-lock mechanism. The toolholder is machined from steel and carries a negative rake angle of -6 degrees, making it suited for heavy interrupted cuts and work on hard or abrasive materials. It is installed by machinists and CNC setup technicians in production and job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for right-hand cutting direction and carries a 93-degree lead angle, positioning it for standard facing and longitudinal turning passes. It is rated for universal primary workpiece material compatibility, covering material groups H, K, M, N, P, and S. The clamp-lock insert retention method provides repeatable insert seating and quick changeover, which is practical in high-volume turning cells where insert indexing frequency is high. No coolant-through capability is present, so external flood or mist coolant delivery must be used where heat management is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDDJN toolholder style with right-hand cutting direction and 93-degree lead angle\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -6 degrees for stable cutting on hard and interrupted workpieces\u003c\/li\u003e\n  \u003cli\u003eClamp-lock insert retention for fast, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eAccepts DN-type negative-rake inserts with a 0.5 inch inscribed circle, including DNGA, DNGM, DNGP, DNMA, DNMG, DNMP, and DNMX geometries\u003c\/li\u003e\n  \u003cli\u003eSteel shank construction with 0.75 x 0.75 inch cross-section and 4.5 inch overall length\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering ISO material groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with DN-type indexable inserts sized to a 0.5 inch inscribed circle, specifically insert compatibility codes DN..43.. including DNGA, DNGM, DNGP, DNMA, DNMG, DNMP, and DNMX insert styles.

The machine spindle and all axis drives must be fully stopped and the control placed in an appropriate safe state before toolholder mounting or insert indexing. Toolholders of this shank size are typically secured in a turret or tool block using the appropriate clamping torque specified by the machine tool builder. Verify insert seating and clamp screw engagement before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DDJN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 93 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..43..
