It features a 135-degree split point tip that drills on contact and prevents walking, eliminating the need for a center punch on most surfaces. A patented core diameter design reduces breakage under load, and the 3-flats shank prevents spin-out in the chuck for consistent control. The black oxide coating increases surface hardness and resists rust, extending service life across repeated use. This bit is suited for licensed tradespeople and experienced DIYers who need reliable, repeatable performance in high-volume drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThe DW1109 is built for drilling through metal, wood, and plastic in both residential and light commercial settings. The 135-degree split point geometry makes it particularly effective on harder materials where a standard 118-degree bit would walk or require excessive feed pressure. Typical install scenarios include mechanical, electrical, and plumbing rough-in work where drilling through studs, sheet metal, or junction box knockouts is routine. Each pack contains 2 bits, making it practical to keep a spare on hand during active jobsite work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point drills on contact and prevents walking without a center punch\u003c\/li\u003e\n  \u003cli\u003ePatented core diameter design reduces breakage under heavy drilling loads\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles metal, wood, and plastic\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating resists rust and increases wear resistance for longer service life\u003c\/li\u003e\n  \u003cli\u003e3-flats shank prevents spin-out in standard drill chucks for improved control\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-pack for jobsite backup availability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or jobsite-stock drill bit compatible with standard 3-jaw drill chucks accepting 9\/64 inch round or 3-flats shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the bit fully into the chuck and tighten all three chuck flats before drilling. Use appropriate RPM for the material being drilled — higher speeds for wood and plastic, reduced speeds for metal — to avoid overheating the bit and reducing its temper. Wear appropriate eye protection per OSHA and site safety requirements. Replace bits showing signs of tip chipping, discoloration from heat, or reduced cutting performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Size\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-speed steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 1-year limited\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: DEWALT ACCESSORIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW1109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51564199969074,"sku":"DW1109","price":18.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4387ced0e496a1fcce7b5c286719ebd_23d9b3c5-38fb-4634-9e7e-a84fa61093f1.jpg?v=1786514054","url":"https:\/\/voomisupply.com\/products\/dewalt-accessories-dw1109-black-oxide-drill-bit-9-64-in-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
