Built from high-speed steel (HSS) with a black and gold finish, it features a 135-degree split-point tip that self-centers on contact and reduces the thrust needed to start a hole. The straight shank measures 0.2600 inches in diameter and 1.25 inches in length. Overall length is 4.125 inches, with a flute length of 2.88 inches. This is a heavy-duty grade bit manufactured to ANSI specification, suited for machinists, pipefitters, ironworkers, and maintenance technicians who drill metal regularly.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on steel and cast iron workpieces in both shop and field environments. The regular spiral flute geometry handles a wide range of metal drilling applications, from structural steel fabrication to mechanical maintenance work. The 3xD flute-to-diameter ratio and tapered web design support efficient chip evacuation at standard drilling speeds. It is sold individually and is well-suited to hand-held drill motors, drill presses, and CNC-style drill heads that accept a straight shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter F size (0.2570 inches) with a tight diameter tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip for self-centering and reduced feed pressure\u003c\/li\u003e\n\u003cli\u003eHSS construction with black and gold finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2 flutes and a 3xD flute-by-diameter ratio\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade, manufactured to ANSI specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or stock drill bit for use in straight-shank drill chucks on hand drills, drill presses, and automated drilling equipment where a Letter F diameter is required for metal drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit requires a drill chuck rated for straight-shank tooling. Secure the shank fully in the chuck before operation and verify that the chuck is tightened with the key before applying power. Use cutting fluid or coolant when drilling steel at sustained depths to preserve edge life. Coolant-through capability is not supported in this bit design.\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: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black\/Gold\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: 2.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: CLE-LINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C18033BP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52086735044914,"sku":"C18033BP","price":248.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63717d303a2ea6401b6692ea61bbb21_f1504253-146b-4f80-8341-7bba5c0e0b2a.jpg?v=1790059859","url":"https:\/\/voomisupply.com\/products\/cle-line-c18033bp-jobber-drill-bit-letter-f-0-2570-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
