Precision Twist Drill 6001314 No. 53 Hss Aircraft Drill Bit

Product Description

The PRECISION TWIST DRILL 6001314 is a No. 53 wire gauge aircraft extension drill bit designed for precision drilling in metal fabrication and aerospace maintenance applications. Built from high speed steel (HSS) with an oxide finish, this bit delivers reliable performance in general-purpose drilling tasks. The 135-degree split point reduces walking on entry and requires less thrust than a standard 118-degree point. At 0.0595 inches in diameter with a 7/8-inch spiral flute length, it is suited for tight-tolerance holes in thin to medium stock. The straight-cylindrical shank measures 0.0595 inches and is compatible with standard drill chucks. A licensed aircraft mechanic or machinist typically installs this tool in handheld or bench-mounted drilling equipment.

This drill bit is built to NAS 907 Type B standards, making it appropriate for aircraft and aerospace maintenance, sheet metal work, and precision machining operations where small-diameter holes are required. The web-thinned, tapered web construction reduces cutting resistance and improves chip evacuation. It is used in residential and commercial shop environments as well as on the flight line or in MRO facilities where close-tolerance drilling is critical.

Key Features

• No. 53 wire gauge diameter: 0.0595 inches for tight-tolerance drilling
• 135-degree split point reduces bit walking and cutting thrust
• High speed steel construction handles a broad range of metals
• Oxide finish provides light surface protection during storage and use
• Web-thinned tapered web improves chip clearance and reduces feed pressure
• Meets NAS 907 Type B standards for aircraft applications

Compatibility

Designed as an OEM-style general-purpose aircraft extension drill bit for use in standard drill chucks accommodating a 0.0595-inch straight-cylindrical shank, consistent with Series 501-6 tooling applications.

Installation Notes

Install and remove drill bits only after the drill motor or press is fully powered down and the chuck key is secured. A machinist or aircraft mechanic should verify chuck concentricity before seating small-diameter bits to avoid run-out that can snap the shank. Follow applicable shop safety standards and, where aerospace work is involved, adhere to the relevant maintenance manual procedures for hole size and finish requirements. Wear appropriate eye protection whenever drilling operations are in progress.
