It features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The Weldon flat shank with three flats resists rotation in the chuck for positive drive during high-torque drilling operations. An oxide finish provides basic lubrication and mild corrosion resistance during use. This bit is a general-purpose tool suited for drilling through a broad range of ferrous metals in production, maintenance, and repair settings.\u003c\/p\u003e\u003cp\u003eThe -20870-E is designed for mechanics-length drilling applications where a shorter, stiffer bit improves hole accuracy in tight quarters or on flat stock. It is appropriate for use on carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel. Right-hand cutting direction is standard for conventional drill press, hand drill, and magnetic drill use. The spiral flute type is regular, and web configuration is parallel with web thinning applied for improved chip clearance and reduced thrust.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E diameter (0.25 inches) for precise sizing to common fastener and reaming applications\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces drill walking without a center punch\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank with three flats prevents bit slippage under torque load\u003c\/li\u003e\n\u003cli\u003eMechanics length (3.5 inches OAL, 2.0-inch flute) provides rigidity for accurate hole placement\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\u003eOxide coating offers surface lubrication and basic protection during cutting operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose mechanics-length drill bit compatible with any standard drill chuck or Weldon flat collet accepting a 0.25-inch shank.

Secure the Weldon flat shank fully in a matching chuck or collet and confirm all set screws engage the flats before operation. Apply cutting fluid or lubricant when drilling stainless steel or high alloy materials to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is degraded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 0.25 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: 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: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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 Material\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -20870-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51691806097714,"sku":"-20870-E","price":17.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4f46af63ab71cba1bf22fbb9b49d8f9.jpg?v=1788289962","url":"https:\/\/voomisupply.com\/products\/import-20870-e-drill-bit-letter-e-0-25-inch-hss-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
