Factory Price L x 12″ HSS Aircraft Extension Drill Bit DWDA/CX12L

Specs

Material: High-Speed Steel (HSS)

Length: 12 inches

Quantity: 1 piece

Model: DWDA/C

Features

Extended 12-inch reach enables drilling in deep holes, thick metals, and confined spaces common in aircraft maintenance and metal fabrication.

HSS construction provides heat and wear resistance for high-speed drilling on alloys and steel.

Engineered for aircraft-use scenarios to reduce bit breakage during repetitive or demanding drilling tasks.

Shank: standard size; exact diameter not disclosed for secure seating in typical drill chucks.

Use cases include engine components, structural frames, and other aerospace metalwork where deep access is required.

Compared to shorter bits, the extended length minimizes tool changes and repositioning in tight or long-through holes.
