Built from high-speed steel (HSS) with a black and gold oxide coating, this bit delivers improved wear resistance and reduced heat buildup during extended drilling cycles. The 135-degree split-point tip reduces walking at entry, enabling accurate starts without a center punch on most flat surfaces. At 2 inches overall length with a 1-inch flute, this is a compact, precision bit suited for tight-clearance applications. Installed by machinists, tool-and-die technicians, and maintenance professionals working with light-gauge metal stock.\u003c\/p\u003e\u003cp\u003eThe C18102 is intended for drilling steel and cast iron workpieces in production and maintenance environments. Its 0.0730-inch diameter corresponds to No. 49 wire gauge, placing it in the small-diameter range where dimensional accuracy and bit rigidity matter most. The regular spiral flute geometry handles chip evacuation efficiently during right-hand drilling in shallow-to-moderate hole depths. This bit suits drill presses, CNC machinery, and hand drills where precise small-diameter holes are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 49 wire gauge diameter: 0.0730 inches for precise small-diameter drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip reduces drill walking and entry burr formation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for heavy-duty service in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eBlack and gold oxide coating improves surface hardness and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with 0.0730-inch shank diameter fits standard chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length replacement drill bit for use in drill presses, CNC equipment, and hand-held drills accepting a straight cylindrical shank.

Power down and de-energize the drill press or machine spindle completely before changing bits. Follow applicable ASME B94.11M and DIN 338 standards for drill selection and use. Avoid side-loading or flexing small-diameter bits, as they are prone to breakage under lateral stress.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 49\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0730 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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0730 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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black and Gold Oxide\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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: 0.2 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: C18102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52054335521074,"sku":"C18102","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d58b798d5f1a66a19890d8d0827a0c51_59b2fb74-48ce-454a-bde6-286d6f3c0acf.jpg?v=1790036819","url":"https:\/\/voomisupply.com\/products\/cle-line-c18102-no-49-hss-jobber-drill-bit-135-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
