Threaded Drill Bits #30

#30 Threaded Shank Cobalt Drill Bits for Aircraft Maintenance

#30 threaded shank cobalt drill bits are precision drilling tools designed for aircraft maintenance, repair, and overhaul applications. These cobalt 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 #30 drill size is commonly used for small-diameter drilling applications, including aircraft sheet metal, components, and fastener holes. The threaded shank design provides a compact connection to compatible threaded drill adapters, making these drills particularly useful when working in the confined spaces often encountered during aircraft maintenance.

Cobalt construction provides increased heat resistance and durability compared with conventional high-speed steel drills. This makes cobalt threaded drills well suited for demanding drilling applications where maintaining cutting performance and tool life is important.

#30 Threaded Drill Bit Sizes and Lengths

BAC offers the #30 threaded cobalt drill in four overall lengths. Selecting the appropriate length allows the technician to match the drill to the available workspace and required reach.

Why Use a #30 Threaded Shank Drill Bit?

Aircraft maintenance often requires drilling small holes in locations where access is restricted and tool control is important. A #30 threaded shank drill provides a compact drilling solution while retaining the durability and heat resistance of cobalt construction.

• #30 drill size: Provides a small-diameter drill size for precision aircraft drilling and fastener-hole applications.
• Threaded shank design: Provides a compact connection when used with a compatible threaded drill adapter.
• 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.
• Four length options: Long, short, stub, and very stubby configurations allow technicians to select the appropriate length for the available workspace.

#30 Drill Bits for Aircraft Maintenance

#30 threaded drills are useful for precision drilling operations involving aircraft sheet metal, structural components, and small fastener holes. The compact threaded configuration can be particularly useful when conventional drill setups are difficult to position because of limited access.

The four available lengths give aircraft maintenance technicians additional flexibility when working around aircraft structure and components. The very stubby and stub configurations are especially useful when minimizing the overall tool length is important, while the long version provides additional reach when access requires it.

Choosing the Correct #30 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 adding unnecessary length.

The 3/8" very stubby provides the most compact configuration. The 9/16" stub provides slightly more reach while remaining very compact. The 1-1/4" short provides a balance between access and reach, while the 2-1/8" long version is appropriate when additional reach is necessary.

NAS 965 Type D Threaded Shank Drill

These #30 threaded shank adapter drills are manufactured to NAS 965 Type D standards and feature a 135-degree split point. NAS 965 is a recognized aerospace tooling specification for threaded shank adapter drills, making this specification particularly relevant to aircraft maintenance and aviation tooling applications.

Threaded Shank Drill Bits for Confined Aircraft Areas

One of the primary advantages of a threaded shank drill is the ability to create a compact drilling setup with a compatible adapter. This can be valuable when drilling aircraft components in confined areas where a conventional drill chuck and drill-bit combination may be difficult to position.

The #30 size combined with the available stub and very stubby lengths gives technicians additional options for accessing tight work areas while maintaining a precise drilling setup.
