Built to toolholder style A-STFP, this right-hand-cut bar features a 5\/8-inch (15.88 mm) shank diameter and an overall length of 10 inches (254 mm). The minimum bore diameter is 0.770 inches (19.56 mm), making it suited for relatively tight bores. The body is constructed from steel and uses a screw-type insert holding method. Coolant-through capability is supported via a 1\/8-27 NPT coolant hole, keeping the cutting zone clear during deep bore passes. It accepts TP-style inserts with a 1\/4-inch inscribed circle and 3\/32-inch thickness.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for shops and machinists performing precision internal diameter work where a compact, rigid toolholder is required. The neutral rake geometry (0-degree rake angle) offers versatility across a range of work materials. It is suited for applications in job shops, production turning cells, and maintenance machining environments where consistent bore quality and repeatable insert indexing are priorities. The A10 designation indicates compatibility with standard tool turret and block holders commonly used on gang-style and turret lathes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand cut orientation for standard internal boring setups\u003c\/li\u003e\n\u003cli\u003eScrew-type insert clamping for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 1\/8-27 NPT port for chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003eNeutral rake (0 degrees) supports broad material compatibility\u003c\/li\u003e\n\u003cli\u003eSteel shank construction provides rigidity in the bore\u003c\/li\u003e\n\u003cli\u003eAccepts TP.. series inserts with 1\/4-inch inscribed circle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TP-style inserts featuring a 1\/4-inch inscribed circle and 3\/32-inch thickness, following toolholder style A-STFP.

Power down and lock out the machine spindle before changing or indexing inserts. Ensure the shank is clamped securely in the tool block or turret to the full recommended engagement depth to minimize overhang and vibration. Do not exceed the minimum bore diameter of 0.770 inches to avoid tool interference with the bore wall.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.770 inches (19.56 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.0 inches (254 mm)\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: A-STFP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TP.. series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.80 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: 1094657\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744683360562,"sku":"1094657","price":261.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eee1d9cbe41da4f92eaef220647a0ee7.jpg?v=1788859924","url":"https:\/\/voomisupply.com\/products\/kennametal-1094657-indexable-boring-bar-5-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
