Built from cobalt steel with a bright, uncoated finish, it delivers strong wear resistance and heat tolerance in production and maintenance machining applications. The tool features a 10 mm counterbore diameter, a 5.5 mm standard pilot diameter for accurate centering, and a 3-flute geometry that balances chip clearance with cutting stability. An 8 mm shank diameter provides rigid tool holding. Machinists, toolmakers, and maintenance technicians install this counterbore in drill presses, milling machines, and CNC machining centers wherever clean, accurate counterbore profiles are required.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for use on ferrous and non-ferrous workpieces in both job-shop and production environments. It is compatible with M5 socket-head cap screws and is applied wherever a 10 mm counterbore recess is needed to recess a fastener head. Typical use cases include machine frames, fixture plates, mechanical assemblies, and structural fabrication where a flush or recessed fastener seating is specified. The overall length of 80 mm provides sufficient clearance for most standard setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for improved hardness and heat resistance over standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip evacuation and cutting surface contact for clean recess profiles\u003c\/li\u003e\n  \u003cli\u003e5.5 mm standard pilot diameter self-centers the tool in the clearance hole for accurate counterbore location\u003c\/li\u003e\n  \u003cli\u003e8 mm shank diameter for secure, rigid tool holding in standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with M5 socket-head cap screws for direct fastener-spec tooling selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M5 socket-head cap screws.

Secure the workpiece firmly before operation and use an appropriate cutting fluid to extend tool life and improve finish quality. Verify the pilot fits freely in the pre-drilled clearance hole before applying feed pressure. Machinists should follow standard shop safety practices and consult applicable machine operating procedures when setting spindle speed and feed rate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 5.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Compatibility\u003c\/strong\u003e: M5 Socket-Head Cap Screw\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\u003eWeight\u003c\/strong\u003e: 0.06 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: 902-000-054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52071263699250,"sku":"902-000-054","price":77.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffb21e68068c1a71fd575eacb3a3336d_85d10382-e80b-49b0-b9da-c44bd3598721.jpg?v=1790048973","url":"https:\/\/voomisupply.com\/products\/keo-902-000-054-solid-pilot-counterbore-10-mm-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
