Milwaukee Black Oxide Aircraft-Length Drill Bit

Milwaukee 48-89-2770 1/8" x 12" Black Oxide Aircraft-Length Drill Bit

The Milwaukee 48-89-2770 is a 1/8" x 12" aircraft length drill bit finished in black oxide, purpose-built for extended-reach drilling on professional jobsites and in production shops. Unlike standard jobber-length bits, this Milwaukee aircraft length bit stretches to a full 12" overall length, giving installers and fabricators the reach needed to bore through thick stock, layered framing, and deep assemblies without switching to extension attachments. The 1/8" diameter delivers a precise, controlled hole size suited to pilot holes, wiring runs, and fine fabrication work, while the black oxide coating helps the bit resist heat buildup and corrosion during use. Whether working on metal fabrication, panel work, or deep structural drilling, the 48-89-2770 gives tradespeople the length and finish they need in a single bit.

Key Features

• Trade Size: 1/8" diameter for precise, controlled hole drilling in a compact bit profile suited to fine fabrication and pilot-hole work.
• Aircraft Length: 12" overall length provides extended reach for drilling through deep materials, thick framing, layered assemblies, and hard-to-access areas where standard-length bits cannot reach.
• Black Oxide Finish: The black oxide coating reduces friction during drilling, helps dissipate heat, and adds a layer of corrosion resistance compared to bare, uncoated steel bits.
• Extended-Reach Design: Purpose-built as an aircraft-length bit, the 48-89-2770 is designed to reach beyond the limits of standard jobber-length or mechanics-length drill bits.
• Milwaukee Reliability: Manufactured by Milwaukee for consistent performance in demanding professional environments.

Aircraft length bits such as the 48-89-2770 are built for situations where a standard-length bit simply will not reach. The added length lets users drill through both sides of a stud or assembly from a single access point, bore through stacked or layered components without repositioning the workpiece, and reach recessed areas within enclosures, panels, and equipment housings that shorter bits cannot access.
