Cleveland C13105 Aircraft Extension Drill Bit 1/8 in Hss

Product Description

The CLEVELAND C13105 is a 1/8 inch diameter aircraft extension drill bit designed for deep-reach drilling applications in metal fabrication, aerospace maintenance, and structural assembly work. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 135-degree split point that is self-centering and reduces walking on hard surfaces without a center punch. The extended 6 inch overall length provides access to fastener locations in recessed or obstructed areas. Two spiral flutes measuring 1.625 inches in length clear chips efficiently during through-hole drilling. Cutting direction is right hand with a tapered, web-thinned web configuration for reduced thrust and cleaner entry.

This bit is suited for general-purpose drilling in sheet metal, aluminum, and mild steel in both production and field repair environments. The extended reach makes it a standard choice for aircraft skin repairs, structural panel work, and any application where a standard-length bit cannot reach the work surface. The straight cylindrical shank accepts standard drill chucks without adapters. It meets NAS 907 Type B standards, making it appropriate for aerospace and precision metalworking applications. Machinists, sheet metal workers, aircraft maintenance technicians, and industrial mechanics are the typical users.

Key Features

• 135-degree split point is self-centering and reduces drill walking on entry
• Web-thinned, tapered web configuration lowers drilling thrust and improves chip ejection
• 6 inch overall length provides extended reach into confined or obstructed areas
• High-speed steel construction handles general-purpose drilling in metal, aluminum, and mild steel
• Right-hand spiral flutes with 1.625 inch flute length clear chips during through-hole drilling
• Meets NAS 907 Type B standard for aerospace and precision metalworking use

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard drill chucks accepting a 1/8 inch straight cylindrical shank. Meets NAS 907 Type B specifications for use in aerospace and precision metalworking applications.

Installation Notes

Installation is performed by machinists, sheet metal workers, and aircraft maintenance technicians using standard or pneumatic drill motors with a compatible chuck. Secure the workpiece before drilling and confirm the chuck is properly tightened onto the straight shank before starting. Use appropriate cutting fluid when drilling harder metals to preserve edge life. Follow applicable facility safety and personal protective equipment requirements when operating rotary cutting tools.
