Threaded Drill Bits #10

#10 Threaded Shank Cobalt Drill Bits for Aircraft Maintenance

#10 threaded shank cobalt drill bits are precision drilling tools designed for aircraft maintenance, repair, and overhaul applications. These threaded shank adapter drills are manufactured to NAS 965 Type D standards and feature a 135-degree split point for accurate starting and controlled drilling.

The #10 drill size provides a small-diameter option for precision drilling applications involving aircraft sheet metal, components, and fastener holes. The threaded shank design provides a compact connection to compatible threaded drill adapters, making these drills useful when working in confined aircraft maintenance areas.

Cobalt construction provides increased heat resistance and durability for demanding drilling applications. The combination of cobalt construction, a 135-degree split point, and threaded shank design makes these drills a specialized option for aircraft maintenance technicians who require precision and compact tooling.

#10 Threaded Drill Bit Sizes and Lengths

BAC offers the #10 threaded drill in three overall lengths. Selecting the appropriate length allows technicians to balance reach, accessibility, and tool control for the specific drilling application.

Why Use a #10 Threaded Shank Drill Bit?

Aircraft maintenance frequently requires drilling small, accurately positioned holes in areas where access is limited. A #10 threaded shank drill provides a compact drilling option while retaining the durability and heat resistance of cobalt construction.

• #10 drill size: Provides a small-diameter drill size for precision aircraft drilling and fastener-hole applications.
• 1/4-28 threaded shank: Designed for use with compatible threaded drill adapters and drilling systems.
• Cobalt construction: Provides increased heat resistance and durability for demanding drilling operations.
• 135-degree split point: Helps the drill start accurately and reduces walking when beginning a hole.
• NAS 965 Type D: Manufactured to the requirements associated with NAS 965 Type D threaded shank adapter drills.
• Three length options: Long, short, and stub configurations allow technicians to select the appropriate drill length for the available workspace.

#10 Drill Bits for Aircraft Maintenance

#10 threaded drills are useful for precision drilling operations involving aircraft sheet metal, structural components, and small fastener holes. Their threaded-shank configuration can be particularly useful when a conventional drill chuck and drill-bit combination is difficult to position.

The three available lengths give aircraft maintenance technicians flexibility when working around aircraft structure and components. The stub configuration provides a particularly compact option for restricted work areas, while the long configuration provides additional reach when required.

Choosing the Correct #10 Drill Length

Drill length should be selected based on the accessibility of the drilling location and the amount of reach required. Whenever practical, choose a configuration that provides adequate access without unnecessary drill length.

The 9/16" stub provides the most compact configuration and is useful when working in restricted spaces. The 1-1/4" short version provides additional reach while remaining relatively compact. The 2-1/8" long version provides the greatest reach when the drilling location requires additional length.

NAS 965 Type D Threaded Shank Drill

These #10 threaded shank adapter drills are manufactured to NAS 965 Type D standards and feature a 135-degree split point. The NAS 965 Type D designation identifies the threaded shank adapter drill configuration and is particularly relevant to aerospace tooling applications.

Threaded Shank Drill Bits for Confined Aircraft Areas

A threaded shank drill can provide a compact drilling arrangement when paired with a compatible adapter. This can be valuable when aircraft structure, installed components, or limited workspace restrict the ability to position a conventional drill and chuck.

The #10 size combined with the short and stub configurations gives technicians additional options for approaching restricted drilling locations while maintaining a precision drilling setup.
