The split point geometry reduces walking on entry and lowers thrust force, making it well-suited for production drilling in steel and cast iron. At 4.875 inches overall length with a 3.5-inch flute, this bit follows the standard jobber proportions most technicians and machinists reach for as a general-purpose drill. The web-thinned, tapered web design improves chip evacuation and keeps cutting action aggressive without excessive heat buildup. It is manufactured to ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for right-hand rotation and designed primarily for ferrous workpiece materials including steel and cast iron. It fits conventional drill chucks with a straight cylindrical shank of 0.3480 inches in diameter. The regular spiral flute pattern suits through-hole and blind-hole applications in maintenance, fabrication, and light manufacturing environments. With a heavy-duty grade rating and high-performance classification, it handles repetitive production cycles as well as one-off service work. The Series 1878 designation places it within CLE-LINE's jobber drill lineup built to consistent dimensional tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter S size at 0.3480 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walk and cutting thrust on entry\u003c\/li\u003e\n  \u003cli\u003eBlack and gold oxide coating improves lubricity and heat resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web promotes chip clearing and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill replacement compatible with any standard drill press, handheld drill, or milling machine chuck that accepts a 0.3480-inch straight shank.

Secure the shank fully in the chuck before operation and confirm the bit runs true before cutting. When drilling steel or cast iron, use a cutting fluid appropriate for ferrous materials to extend bit life and improve hole finish. Do not exceed the recommended feed rate for the material; forcing the bit increases heat and risks premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3480 inches\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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black\/Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3748 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1878\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.92 pounds\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: CLE-LINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C18046\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":51996015526194,"sku":"C18046","price":16.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d58b798d5f1a66a19890d8d0827a0c51_6758e744-f9ae-4c6b-96bc-4e0080ab1859.jpg?v=1789993064","url":"https:\/\/voomisupply.com\/products\/cle-line-c18046-letter-s-hss-jobber-drill-bit-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
