At 12 inches in overall length, this single-end bit features a 135-degree split point tip that starts on contact and prevents walking, producing fast, accurate holes without a center punch. The THUNDERBOLT web construction extends service life and improves drilling speed. A 3-flat shank design locks the bit firmly in the chuck to prevent slipping under load. Black oxide coating adds lubricity and corrosion resistance for extended bit life.\u003c\/p\u003e\u003cp\u003eAircraft-length drill bits are used where standard-length bits cannot reach — deep assemblies, structural framing, HVAC ductwork penetrations, electrical conduit rough-in, and plumbing rough-in through deep framing members. The reduced shank diameter allows this 12-inch bit to seat in a standard 3\/8-inch chuck, making it compatible with a wide range of corded and cordless drills already on the job. Electricians, plumbers, HVAC technicians, and general contractors regularly use aircraft-length bits for through-wall and through-joist drilling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point tip starts on contact and prevents walking for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eTHUNDERBOLT web design provides longer service life and faster drilling performance\u003c\/li\u003e\n\u003cli\u003e3-flat shank prevents slipping in the drill chuck during high-torque applications\u003c\/li\u003e\n\u003cli\u003eExtended 12-inch aircraft length reaches deep or obstructed drilling locations\u003c\/li\u003e\n\u003cli\u003eReduced shank diameter fits standard 3\/8-inch drill chucks\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating resists corrosion and provides lubricity to reduce friction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch drill chucks on corded and cordless drills.

Ensure the 3-flat shank is fully seated and the chuck is tightened securely before operation. Use appropriate drilling speed for the material being drilled — lower speeds for metal, higher speeds for wood and PVC. Wear eye protection and verify that no utilities are present in the drilling path before proceeding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 135-Degree Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-Flat Secure-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13.87 x 1.87 x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Metal, Wood, PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2771\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51343046738226,"sku":"48-89-2771","price":33.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512786.jpg?v=1782014776","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2771-black-oxide-aircraft-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
