AT Aircraft Extension / Extra Length

Alfa Tools produces aircraft extension drills—also known as extra-length or long-series drills—crafted from high-speed steel (HSS) and designed with extended flutes and overall lengths for deep hole drilling in tight spaces, thick materials, and hard-to-access areas. Our comprehensive range includes Type B and Type J geometries in both 6-inch and 12-inch lengths, available in sizes from 3/64" to 1/2" diameter. These specialty drill bits are ideal for aerospace, automotive, industrial manufacturing, maintenance, and repair applications.
