Built from steel with a 3\/8-inch shank diameter and 4-inch overall length, it accepts screw-clamped diamond-shaped inserts with a 1\/4-inch inscribed circle. The minimum bore diameter is 0.492 inches with a maximum bore depth of 0.875 inches. A 3-degree lead angle and neutral rake angle provide stable cutting geometry at the insert. This tool is installed and operated by machinists and CNC turning technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-diameter internal boring applications in light to medium material removal operations. The MINI S-SDUC toolholder style accommodates compact bores where standard holders will not fit. Compatible insert size code is 21.51, and the insert inscribed circle measures 0.25 inches. The right-hand cutting direction makes it appropriate for conventional lathe setups. It is a single-use toolholder without coolant-through capability, intended for dry or flood-coolant applications where through-spindle coolant is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.492 inches enables small-diameter internal operations\u003c\/li\u003e\n\u003cli\u003eScrew-clamped diamond insert retention for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003e3-degree lead angle with neutral rake for stable cutting geometry\u003c\/li\u003e\n\u003cli\u003eSteel construction provides rigidity in the MINI S-SDUC form factor\u003c\/li\u003e\n\u003cli\u003eCompatible with MINI S-SDUC inserts, insert size code 21.51, 1\/4-inch inscribed circle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for MINI S-SDUC indexable boring bar toolholders accepting diamond-shaped inserts with a 1\/4-inch inscribed circle and insert size code 21.51.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar is installed and set up by qualified machinists or CNC turning technicians. Ensure the lathe or turning center is fully powered down and the spindle is locked before mounting or changing the toolholder. Secure the shank in a tool block or turret station per machine manufacturer specifications. Index or replace inserts using the appropriate screw-type fastener; do not overtighten, as this can damage the insert pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.492 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MINI S-SDUC\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\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eCompatible Insert Size Code\u003c\/strong\u003e: 21.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.324 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: DORIAN TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73310155540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67906163081522,"sku":"73310155540","price":113.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_8522bfee-a87a-45b0-8f7b-d04c88ba1d51.jpg?v=1791165505","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310155540-indexable-boring-bar-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
