Extension Drill Aircraft HSS

The Cleveland Golf C13188 is a high-speed steel extension drill built for aircraft maintenance and deep-hole machining. Its 12-inch reach suits technicians who need access through structural members or confined assemblies.

Thermals noise and power draw

High-speed steel construction manages heat during extended drilling cycles in tough alloys. The split-point geometry reduces thrust force, lowering motor load and vibration for smoother operation on pneumatic or electric drives.

135-degree split point decides fit

A 135-degree split point with 21 to 34-degree helix handles 1/4-inch fractional holes up to one inch deep at 4xD. Buyers needing coated bits, larger diameters or different point angles should select another tool.

Questions about this item

How do I install the 1/4-inch HSS drill bit in my drill chuck, and what step do people get wrong?

Open the chuck fully, insert the shank until it seats, then tighten securely; the common error is not seating the bit fully before tightening.

What maintenance will the high speed steel drill bit need later?

Resharpen the 135-degree split point when cutting slows, and wipe the bright finish clean after each use to prevent corrosion.

What limit appears first when drilling continuously with this 12-inch extension bit?

Chip evacuation becomes difficult at the 1-inch maximum depth, causing heat buildup and reduced cutting efficiency.
