Precision Twist Drill 6001220 7/64 Inch Aircraft Drill Bit

Product Description

The PRECISION TWIST DRILL 6001220 is a high speed steel aircraft extension drill bit designed for deep-hole and extended-reach drilling applications. The 7/64 inch (0.1094 inch decimal) diameter bit features a 135-degree split point that self-centers on contact, reducing walking and eliminating the need for a center punch on most surfaces. The spiral flute runs 1.5 inches in length and the overall tool extends to 6 inches, providing the clearance required when drilling through thick stock, structural members, or hard-to-reach locations. The oxide finish improves lubrication retention and surface hardness. This bit is sold individually and is suited for use by aviation maintenance technicians, pipefitters, electricians, and general fabrication tradespeople.

The 6001220 is built to NAS 907 Type B standards, making it appropriate for aerospace and structural drilling applications where precise diameter tolerance and point geometry are required. The 6-inch overall length makes it practical for drilling through deep structural members, box tubing, panels, or conduit bodies where a standard-length bit cannot reach. General-purpose performance rating makes it a versatile stock item for trade shops and field service kits alike.

Key Features

• 135-degree split point self-centers on contact, reducing drill walk without a center punch
• 6-inch overall length provides extended reach for deep or obstructed drilling locations
• High speed steel construction handles general-purpose ferrous and non-ferrous materials
• Oxide finish aids lubrication retention and reduces friction during cutting
• Web-thinned tapered web configuration reduces thrust force and improves chip evacuation
• NAS 907 Type B compliant for aerospace and structural applications

Compatibility

Designed as an OEM-style replacement or stock bit for standard 7/64 inch straight-cylindrical shank drill chucks used in corded and cordless drills, drill presses, and right-angle drill attachments.

Installation Notes

Installation is performed by any qualified tradesperson using a drill press, corded drill, or pneumatic drill with a compatible chuck. Secure the workpiece firmly before drilling and verify chuck grip on the straight-cylindrical shank before applying feed pressure. When drilling metals, use appropriate cutting fluid to extend bit life and maintain dimensional accuracy. Wear eye protection per standard shop safety practice.
