It features a 1.203-inch cutting diameter, an oversize pilot diameter of 0.781 inches, and three flutes for efficient chip evacuation. Constructed from cobalt steel, the tool handles tough ferrous materials without premature edge wear. The straight-cylindrical shank measures 0.75 inches in diameter and the overall length is 7 inches, making it suitable for standard drill press, milling, or CNC setups. Machinists, tool-and-die workers, and maintenance technicians install this tool where socket-head cap screw seat geometry must be accurately cut or refinished.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is sized specifically for 0.75-inch socket-head cap screws and is used in production machining, maintenance repair, and fabrication environments. The oversize pilot registers against a pre-drilled clearance hole to keep the counterbore concentric during the cut. Forward cutting direction makes it compatible with standard right-hand spindle machines. Typical applications include creating or cleaning up fastener seats in steel plate, structural weldments, and machined assemblies where socket-head cap screws must sit flush or below the surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.203-inch counterbore diameter sized for 0.75-inch socket-head cap screw seats\u003c\/li\u003e\n  \u003cli\u003eOversize pilot diameter of 0.781 inches for positive hole registration and concentricity\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry promotes chip clearance during the cut\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides heat and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection of cutting edges\u003c\/li\u003e\n  \u003cli\u003e7-inch overall length accommodates standard spindle reach requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 0.75-inch socket-head cap screws.

Secure the 0.75-inch straight shank firmly in a collet or end-mill holder before operation and verify runout before cutting. Always power down and lock out the spindle before changing or inspecting the tool. Do not exceed the recommended feed and speed parameters for cobalt tooling in the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 1.203 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.781 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Oversize\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Compatibility\u003c\/strong\u003e: Socket-Head Cap Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: KEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 902-000-035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51974299746610,"sku":"902-000-035","price":229.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb56c16bb3509a81ee753068af95266f.jpg?v=1789976828","url":"https:\/\/voomisupply.com\/products\/keo-902-000-035-solid-pilot-counterbore-1-203-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
