Built from steel, it accepts CDC and CSBI inserts secured by a screw-clamping insert holding method. The positive rake geometry at a 5-degree lead angle reduces cutting forces and supports clean bore finishes at small diameters. With a minimum bore diameter of 0.208 inches and a maximum bore depth of 1 inch, this bar is suited for tight-tolerance small-bore work. Through-coolant capability with a 0.040-inch coolant hole diameter keeps the cutting zone clear and helps manage heat during extended cuts.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments including job shops, production turning cells, and tool and die operations. It fits applications where small internal diameters require a rigid, indexable solution rather than a brazed or solid boring tool. The 0.5-inch shank diameter makes it compatible with standard boring bar holders and quick-change tooling systems commonly found on CNC lathes. It is installed and operated by machinists and CNC operators working to close bore tolerances in steel, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand CSBI toolholder style with screw-clamping insert retention\u003c\/li\u003e\n\u003cli\u003eAccepts CDC and CSBI inserts with a 0.156-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 0.040-inch coolant hole for chip evacuation and thermal control\u003c\/li\u003e\n\u003cli\u003ePositive rake angle at 5-degree lead reduces cutting forces on small-bore work\u003c\/li\u003e\n\u003cli\u003eSteel construction with 0.5-inch shank diameter for secure toolholder fitment\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.75 inches provides rigidity while maintaining access in confined bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with CDC and CSBI indexable inserts.

Ensure the machine spindle is fully stopped and the machine is locked out before changing or seating the boring bar. Torque the insert screw to the tooling manufacturer guidelines using the appropriate Torx or hex key — do not overtighten, as insert seats on small boring bars are precision-ground surfaces. Verify through-coolant passages are clear before use and confirm shank clamp contact is uniform to prevent chatter at depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.208 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 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: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.104 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CDC, CSBI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: CSBI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\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: 1937982\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737204588850,"sku":"1937982","price":301.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dbcdf8454ab8a12e56e3b4dd09bd782.jpg?v=1788785556","url":"https:\/\/voomisupply.com\/products\/kennametal-1937982-indexable-boring-bar-right-hand-csbi","provider":"Voomi Supply","version":"1.0","type":"link"}
