Ford 40510930 Combo Drill Countersink 1\/4 in Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD 40510930 is a solid carbide combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built to Series 405 specifications, it carries a No. 3 trade size with a 1\/4-inch body diameter, a 7\/64-inch drill point diameter, and a 7\/64-inch drill point length. The 60-degree included angle produces clean, accurate countersinks suited to fastener seating in demanding materials. A bright polished finish reduces friction during cutting. This tool is intended for machinists, tool-and-die professionals, and precision fabricators who require consistent, repeatable countersink geometry.\u003c\/p\u003e\n\u003cp\u003eThe 40510930 is rated for use in cast iron, hardened steel, special alloy, stainless steel, and carbon steel. Its 5-inch overall length qualifies it as a long-length tool, giving it reach for deeper setups or fixtures where standard-length tooling cannot engage the workpiece. Right-hand cut direction and double end type provide extended tool life by allowing the operator to flip to the second end when the first dulls. The plain cutting edge style suits general-purpose countersinking and drilling applications across production and maintenance machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance in difficult workpiece materials\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for accurate countersink geometry on common fastener styles\u003c\/li\u003e\n  \u003cli\u003eDouble end design extends usable tool life\u003c\/li\u003e\n  \u003cli\u003eLong-length at 5 inches overall for deep fixture or extended-reach setups\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces chip adhesion and cutting friction\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, plain cutting edge for standard CNC and manual spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style combination drill countersink for use in standard collet chucks and drill presses accepting 1\/4-inch body diameter tooling.

Power down and de-energize the spindle completely before changing tooling. Secure the tool firmly in the holder to the appropriate clamping specification per the machine manufacturer before operating. Inspect both cutting ends for chipping or wear before each use, as carbide tooling can fracture if run in a damaged condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 405\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong Length Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hardened Steel, Special Alloy, Stainless Steel, Steel\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: M.A. FORD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40510930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51744007094578,"sku":"40510930","price":109.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d8a4975052732562cfa24eb550dbab4.jpg?v=1788852805","url":"https:\/\/voomisupply.com\/products\/m-a-ford-40510930-combo-drill-countersink-1-4-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
