Authentic 45 X 12″ Aircraft Extension Drill Bit Cobalt GLBCOX1245

Specs

Quantity: 1 PC

Diameter: #45

Overall length: 12″

Material: Cobalt alloy

Type: Aircraft extension drill bit for deep-hole drilling in metal

Features

Cobalt alloy composition provides enhanced hardness and heat resistance for drilling through hard metals, improving wear life compared with standard HSS bits.

12″ reach enables deep-hole drilling into recessed cavities, thick workpieces, or through assemblies common in aerospace and metal fabrication.

Aircraft extension design addresses industrial maintenance and fabrication tasks that require extended reach and reliable entry into metal workpieces.

Suitable for metalworking projects requiring dependable performance on steel, stainless steel, and other hard alloys.

Best paired with rigid setups to minimize deflection when drilling deep holes in metal workpieces.
