Built from high-speed steel (HSS) with an oxide finish, this bit features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. The Weldon flat shank with three flats provides a positive, slip-resistant grip in compatible chucks. At 5 inches overall length with a 3-3\/8 inch flute, it is sized for close-quarters work where standard-length bits are impractical. Right-hand cut with a regular spiral flute and parallel web configuration for consistent chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces. It is a general-purpose mechanics bit appropriate for use by machinists, pipefitters, ironworkers, and mechanical contractors who need a compact, rigid bit for tight-clearance drilling applications on structural members, pipe flanges, brackets, and similar metal components. The web-thinned geometry reduces thrust load when driving through harder stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walk and improves starting accuracy without a center punch\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy steel\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with 3 flats prevents rotation and slippage in compatible drill chucks\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild lubricity and corrosion resistance during use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web design reduces drilling thrust and heat buildup\u003c\/li\u003e\n  \u003cli\u003eMechanics length (5 inches OAL) suits confined-space and close-clearance drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanics-length drill bit for use in Weldon flat shank-compatible drill chucks and holders; suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the bit securely in a Weldon flat-compatible chuck, ensuring all three flats are properly engaged before applying torque. Always wear appropriate eye protection and secure the workpiece before drilling. Use cutting fluid when drilling stainless steel or high alloy materials to extend bit life and manage heat. Inspect the cutting edges for wear before each use and replace the bit if the point shows signs of chipping or dulling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/8 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Carbon Steel, Cast Iron, High Alloy Steel, High Tensile Strength Alloy, Stainless Steel, 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\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: 20928\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51696709108018,"sku":"20928","price":84.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fad7e48c57f4002cf075a69ce374d6ba.jpg?v=1788345470","url":"https:\/\/voomisupply.com\/products\/import-20928-mechanics-drill-bit-1-2-inch-hss-weldon","provider":"Voomi Supply","version":"1.0","type":"link"}
