Chicago-Latrobe 11184 #60 Aircraft Extension Drill
This Chicago-Latrobe 11184 drill bit is a #60 size aircraft extension drill designed for precision drilling in tight or deep locations. It is intended for machinists and maintenance technicians who need accurate holes in metal using high-speed steel tooling.
Check your chuck capacity and reach requirements
Verify that your drill chuck accepts the #60 shank and that the 11/16 inch maximum drilling depth meets your workpiece thickness. The 135 degree split point reduces walking, but ensure your application suits a 28 degree helix angle and wire gauge sizing.
Sustained drilling performance
The high-speed steel construction with black oxide coating resists wear and heat buildup during extended drilling cycles. The split-point geometry maintains centring accuracy over repeated use, while the material grade supports high-performance machining without premature dulling.

Questions about this item
Does the 11184 #60 drill arrive as a single bit or a set, and will I need a longer extension separately?
The listing describes one aircraft extension drill at size #60; no multi-pack or additional extension is mentioned.
Should I choose this 135° split-point bit over a standard 118° point for the same #60 size?
The 135° split-point geometry is designed to reduce walking and cut cleaner in hard materials, unlike a conventional 118° point.
What does the 11/16 in maximum drilling depth mean when the bit is chucked in my drill press?
You can drill holes up to 11/16 in deep before the flutes or shank limit further advance.
