At 12 inches in overall length, it gives technicians and tradespeople the clearance needed for hard-to-access bore locations without sacrificing accuracy. The 135-degree split point tip starts on contact to eliminate walking and deliver clean, precise holes. A THUNDERBOLT web construction increases durability and supports faster drilling cycles. The black oxide coating reduces friction and resists corrosion, extending service life in demanding field conditions.\u003c\/p\u003e\u003cp\u003eThis bit is suited for applications where standard-length drill bits cannot reach — deep structural members, stacked sheet metal, electrical rough-in through framing, and plumbing penetrations through thick assemblies. The reduced shank diameter allows use in 3\/8-inch chucks, making it compatible with a wide range of cordless and corded drills already on the job site. HVAC, electrical, and plumbing installers who regularly drill through multiple layers of material will find this bit practical for everyday rough-in work.\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 construction provides longer service life and faster drilling cycles\u003c\/li\u003e\n\u003cli\u003e3-flat Secure-Grip shank locks into drill chuck to prevent bit rotation and slipping\u003c\/li\u003e\n\u003cli\u003eReduced shank diameter fits standard 3\/8-inch chucks\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and resists corrosion\u003c\/li\u003e\n\u003cli\u003eExtended 12-inch aircraft length reaches deep or obstructed drilling locations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3\/8-inch and larger drill chucks; suitable for drilling metal, wood, and PVC in residential and commercial trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed electrician, plumber, or HVAC installer typically uses aircraft-length bits for rough-in drilling through framing and structural assemblies. Secure the bit fully in the chuck before operation and confirm the 3-flat shank is properly seated. Disconnect power to the drill before changing bits. Use appropriate cutting fluid when drilling through metal to reduce heat buildup and extend bit life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 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\u003eShank Type\u003c\/strong\u003e: 3-flat Secure-Grip, reduced diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Chuck Size\u003c\/strong\u003e: 3\/8 inches and larger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Compatibility\u003c\/strong\u003e: Metal, wood, PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\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: 48-89-2775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51344416375090,"sku":"48-89-2775","price":66.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310512793.jpg?v=1782035365","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2775-black-oxide-aircraft-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
