Built from steel with a 2-inch shank diameter and a 16-inch overall length, this bar accepts CNM 543-series diamond-shaped inserts secured by a pin-and-clamp holding method. The minimum bore diameter is 2.562 inches, making it suited for medium-to-large bore work. The negative rake geometry at -7 degrees and a 5-degree lead angle promote stable cutting action and controlled chip formation in demanding applications. Machinists and toolroom professionals install and operate this bar as part of a rigid, qualified boring setup.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production and job-shop environments where accurate internal diameter finishing or roughing is required. The S-MCLN toolholder style is a standard configuration found on turrets, boring mills, and engine lathes equipped to accept 2-inch round-shank tooling. The 16-inch overall length provides reach for deeper bore applications. The center-to-cutting-edge dimension of 1.281 inches governs positioning in the tool block. Compatible CNM 543 inserts have a 5\/8-inch inscribed circle and a 1\/4-inch insert thickness. Coolant-through capability is not featured on this bar.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 2.562 inches for medium-to-large bore applications\u003c\/li\u003e\n\u003cli\u003e2-inch shank diameter and 16-inch overall length for extended reach setups\u003c\/li\u003e\n\u003cli\u003eAccepts CNM 543-series diamond-shaped inserts with pin-and-clamp retention\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -7 degrees with a 5-degree lead angle for stable cutting\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability under interrupted or continuous cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard lathe and boring mill configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNM 543-series indexable inserts featuring a 5\/8-inch inscribed circle, 1\/4-inch thickness, and diamond insert shape.

The shank must be clamped securely in a properly sized boring bar holder or turret block with adequate overhang minimized to reduce vibration. Insert indexing or replacement requires removing the pin-and-clamp retaining hardware using appropriate tooling per the insert manufacturer's instructions. Verify bore centerline alignment before engaging a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 2.562 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 5 degrees\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: -7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1.281 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CNM 543\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Pin and Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: S-MCLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.6 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: 73310155030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67910918996274,"sku":"73310155030","price":484.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_cd68843b-996d-4a26-b6ac-f8584d841ff9.jpg?v=1791201523","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310155030-indexable-boring-bar-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
