It features a neutral rake geometry with a 0-degree rake angle and a screw-on insert clamping method that provides secure, repeatable insert seating. The 0.5-inch by 0.5-inch steel shank gives it a compact, rigid profile suited for tight tool post clearances. At 3.5 inches overall length, this toolholder accepts DC..21.5. series inserts with a 0.25-inch inscribed circle. It is installed by machinists and CNC operators in production and job-shop turning environments.\u003c\/p\u003e\u003cp\u003eThis toolholder is used in external turning applications where a neutral rake angle is required for balanced cutting forces. The 3-degree lead angle positions the insert for general-purpose turning across a range of ferrous and non-ferrous workpiece materials. The back-of-bar to cutting edge measurement is 0.625 inches, which determines centerline positioning on the lathe. Typical applications include facing, straight turning, and light contouring on parts held in a chuck or between centers. No coolant-through capability is present, so external flood or mist coolant delivery is standard practice for this holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand SDJC toolholder style with 3-degree lead angle and neutral rake\u003c\/li\u003e\n\u003cli\u003eScrew-on insert clamping method for secure, low-profile insert retention\u003c\/li\u003e\n\u003cli\u003eAccepts DC..21.5. series inserts with 0.25-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel shank construction for rigidity and durability\u003c\/li\u003e\n\u003cli\u003eCompact 0.5 inch x 0.5 inch shank fits standard tool posts and turrets\u003c\/li\u003e\n\u003cli\u003e3.5-inch overall length with 0.62-inch head length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DC..21.5. series indexable inserts, specifically compatible with DC.. 21.51 insert geometry per Kennametal catalog designation SDJCR L082.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists working on CNC turning centers or manual engine lathes. The machine spindle must be brought to a full stop and the turret or tool post de-energized before mounting or changing the toolholder. Ensure the insert pocket and clamping screw threads are clean and free of chips before seating a new insert. Torque the clamping screw using the appropriate Kennametal torx or hex key as specified in the insert manufacturer documentation for this insert style.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SDJC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DC..21.5.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2837 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1094521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739160412466,"sku":"1094521","price":215.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a6561ef8ee7c8c5ca93463f1d6b91d3.jpg?v=1788810541","url":"https:\/\/voomisupply.com\/products\/kennametal-1094521-sdjc-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
