Built on the BSTJO toolholder style, this bar accepts TPGT 33 triangular inserts secured by a screw-clamp holding method, providing consistent insert positioning and repeatable cutting performance. The shank diameter is 3\/4 inches and the overall length is 10 inches, making it a practical reach-in bar for moderate-depth bores. The minimum bore diameter is 1 inch, and the center-to-cutting-edge distance is 0.5 inches. The tool body is constructed of steel and is configured for right-hand cutting with a negative rake angle of -2 degrees and a 2-degree lead angle. Machinists and toolroom technicians working on CNC lathes and boring mills are the primary users of this bar.\u003c\/p\u003e\n\u003cp\u003eThe 2000W2A is suited for finish and semi-finish boring in ferrous and non-ferrous materials where TPGT 33 insert geometries are appropriate. The BSTJO series is commonly found in job shops and production environments running turning centers or horizontal boring operations. The 1-inch minimum bore diameter makes it applicable to a range of small-to-mid-size workpiece bores. Coolant-through capability is not included on this bar, so external coolant delivery or flood cooling should be planned during setup. This tool ships as a single unit without inserts included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBSTJO toolholder style accepts TPGT 33 triangular inserts with screw clamping\u003c\/li\u003e\n  \u003cli\u003e1 inch minimum bore diameter with 0.5 inch center-to-cutting-edge measurement\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch shank diameter, 10 inch overall length for moderate-depth boring applications\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle (-2 degrees) and 2-degree lead angle for controlled cutting geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, compatible with standard CNC lathe and boring mill setups\u003c\/li\u003e\n  \u003cli\u003eSteel tool body construction for rigidity and durability in production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TPGT 33 series triangular inserts with a 3\/8 inch inscribed circle and 3\/16 inch (0.1875 inches) thickness.

Before mounting the boring bar, confirm the machine spindle is powered down and the turret or spindle is fully locked out per facility lockout\/tagout procedures. Secure the 3\/4 inch shank in an appropriately sized toolholder or turret station, ensuring adequate clamping length to minimize overhang vibration. Insert torque specifications should follow the insert manufacturer recommendations included with TPGT 33 insert packaging.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: BSTJO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BSTJO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TPGT 33\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: -2 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 2 degrees\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2000W2A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51747744186674,"sku":"2000W2A","price":205.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92d42c7b5a3da64160ca157d8e17d11d_9bdf6a9b-06c2-4982-9b1a-2c64a8665649.jpg?v=1788884934","url":"https:\/\/voomisupply.com\/products\/sumitomo-2000w2a-indexable-boring-bar-1-in-bore-bstjo","provider":"Voomi Supply","version":"1.0","type":"link"}
