Specs

Quantity: 1 piece

Diameter: 5/32 in (0.15625 in)

Length: 6 in overall

Material: cobalt alloy steel

Type: aircraft extension drill bit (long-reach)

Features

Long-reach design with a 6″ overall length to access recessed or hard-to-reach holes common in aircraft maintenance and aerospace assemblies.

Cobalt alloy construction provides enhanced hardness and heat resistance, extending cutting life when drilling through hard metals often encountered in aviation components.

Wear-resistance benefits from cobalt content help maintain hole size and reduce premature dulling under high-speed drilling conditions.

Precise 5/32″ hole diameter supports accurate alignment of fasteners and fittings in aerospace tasks.

Single-piece extension design suitable for tasks requiring extended reach without added assembly components.

Ideal for aircraft mechanics, aerospace machinists, and maintenance technicians tackling recessed bore work and alignment-critical drilling jobs.
