  • Product typeDrill Accessories
  • Main materialHigh speed steel
  • 12-inch reach accesses deep or confined holes

High-Speed Steel Aircraft Extension Drill

This drill accessory is manufactured from high-speed steel with a bright finish. It features a 135-degree split point designed to reduce walking and improve penetration. The fractional size is 5/32 inch with a decimal equivalent of 0.1562 inches. The flute length measures 2 inches while the overall length reaches 12 inches.

Suited For Deep-Hole Drilling Tasks

Mechanics and technicians working in aerospace or heavy-duty maintenance will value the extra reach for inaccessible holes. The jobbers-length flute adds rigidity during deep drilling operations. Buyers who need a standard-length drill for general bench work should look at something else. This tool is not designed for hand-held use without proper support or for drilling materials outside its rated capacity.

Meets NAS 907 Type B Aerospace Specification

The drill meets or exceeds National Aerospace Standards 907 Type B 2007 specifications. This certification confirms the tool is manufactured to the tolerances required for aerospace applications. Compliance with this standard is the primary factor determining suitability for approved aviation maintenance and manufacturing workflows.

Questions about this item

How much heat does the 135-degree split point generate during extended drilling sessions?

The 135-degree split point on this high-speed steel drill reduces thrust and heat buildup, allowing cooler operation during prolonged use in deep or inaccessible holes.

What chuck size is required to hold the straight shank of this 12-inch aircraft extension drill?

A drill chuck capable of gripping a 5/32-inch (0.1562 decimal) straight shank is needed to secure this extension drill for operation.

Will the 2-inch flute length on this 12-inch overall drill maintain rigidity when used with older drill presses?

The jobbers-length flute keeps the drill more rigid despite the extra 12-inch reach, helping it perform accurately on older drill presses without excessive deflection.
