Aircraft Extension Drill 5/16 Inch

The Cleveland Golf C13115 is a jobber length aircraft extension drill bit manufactured from high speed steel. It is designed for general purpose drilling in metal, wood and plastic where extended reach is required. The fractional 5/16 inch size suits maintenance, fabrication and assembly tasks.

High Speed Steel Build with Split Point

The bright uncoated high speed steel construction provides durability and heat resistance during prolonged use. A 135 degree split point geometry reduces walking and allows the bit to start on contact without a centre punch. The straight shank fits standard three jaw chucks and quick change adapters.

5/16 Inch Diameter Decides Fit

The drill bit diameter of 5/16 inch (decimal equivalent .3125) is the single specification that determines compatibility with the intended hole size. Buyers who need a different diameter or a shorter overall length must select another part number.
