It is designed for high-performance drilling in aluminum and non-ferrous materials where tool life and hole quality are critical. The bit features a regular spiral flute with right-hand cutting direction and runs coolant-through capability, making it well suited for production environments. Overall length is 4.2969 inches with a flute length of 2.2031 inches. Licensed machinists, tool-and-die technicians, and CNC operators are the typical end users.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for machining aluminum, copper, brass, and other non-ferrous materials in both job-shop and production-floor settings. The coolant-through design supports deep-hole drilling cycles where chip evacuation and heat management are priorities. The straight cylindrical shank fits standard drill chucks and collet systems without modification, making it easy to deploy on CNC machining centers, drill presses, and multi-axis equipment. The 5xD flute-to-diameter ratio allows for moderate depth-of-cut applications common in fixture and component fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous machining\u003c\/li\u003e\n\u003cli\u003eDLC coating reduces friction and built-up edge when cutting aluminum and soft metals\u003c\/li\u003e\n\u003cli\u003e118-degree point angle suits general-purpose entry geometry on non-ferrous stock\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation in deeper drilling cycles\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with right-hand cut for standard CNC and manual spindle setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank (0.2656 inches diameter) fits standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill replacement for Letter F sizing applications in aluminum and non-ferrous material drilling operations; compatible with any drill chuck or collet system accepting a 0.2656-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the shank fully in the chuck or collet to the recommended engagement depth before operation; verify runout with a dial indicator before beginning a production run. Power down or e-stop the spindle and confirm zero rotation before changing or inspecting the tool. Coolant-through lines should be confirmed clear and at proper pressure before use to protect both the tool and the workpiece surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2969 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2656 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736180556082,"sku":"4500293","price":166.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ebf87571eae376823ecc25fe2ed8bbf.jpg?v=1788776382","url":"https:\/\/voomisupply.com\/products\/accupro-4500293-jobber-drill-letter-f-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
