It measures 3\/16 inch (0.1875 inch) in diameter with a 3-inch overall length and a 1-7\/8-inch flute length. The 135-degree split point reduces walking on contact and eliminates the need for a center punch on most surfaces. An oxide coating provides baseline corrosion resistance and reduces friction during cutting. The parallel web configuration and web-thinned geometry keep cutting forces manageable across a range of material hardnesses. Machinists, maintenance technicians, and metalworkers are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and similar ferrous materials. The mechanics-length body fits standard drill chucks and is compact enough for use in tight-clearance applications where a jobber-length bit would be awkward. The right-hand cut and spiral flute design eject chips efficiently during through-hole and blind-hole operations in both bench-drill and handheld-drill setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walk and eliminates center-punch steps on most metal surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles general-purpose metal drilling without specialized tooling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web geometry lowers cutting resistance across hard and soft ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces surface friction and provides light corrosion protection during storage and use\u003c\/li\u003e\n  \u003cli\u003eMechanics length (3-inch OAL) fits standard chucks and suits confined-space drilling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute ejects chips consistently in both through-hole and blind-hole operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the workpiece firmly before drilling to prevent rotation and bit breakage. Use cutting fluid or a suitable coolant when drilling stainless steel or high-alloy materials to extend bit life and maintain dimensional accuracy. Apply steady, consistent feed pressure — excessive force can overheat HSS bits and cause premature dulling or breakage. Inspect the cutting edges for wear before each use and replace the bit when point geometry degrades noticeably.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-7\/8 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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Carbon Steel, Cast Iron, High Alloy Steel, High Tensile Strength Alloy, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA--20908-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51691695636786,"sku":"BDNA--20908-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e86a9ac9a1e7ee80d04fbf0fcf8910c.jpg?v=1788288609","url":"https:\/\/voomisupply.com\/products\/import-bdna-20908-1-mechanics-drill-bit-3-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
