Value Collection 01435122 Aircraft Extension Drill Bit Set 25pc

Product Description

The VALUE COLLECTION 01435122 is a 25-piece aircraft extension length drill bit set engineered for metalworking and general-purpose drilling applications. Each bit is manufactured from high-speed steel with an oxide finish that helps reduce friction and extend service life. The set covers a range from 1/8 inch minimum to 1/2 inch maximum hole size, stepping in 1/64-inch increments, and all bits feature a 118-degree standard point angle with a straight shank for broad chuck compatibility. At 12 inches overall length, these bits are designed to reach into deep cavities, structural members, and confined spaces where standard-length bits cannot reach. Licensed trades and industrial maintenance technicians alike will find this set suited to demanding production and service work.

This set is intended for metalworking and multipurpose drilling in both shop and field environments. The extended 12-inch overall length makes it particularly useful for drilling through structural steel, aluminum framing, HVAC ductwork, electrical panels, and similar applications where access depth is a constraint. The straight shank fits standard three-jaw chucks on corded and cordless drills. Bits are stored and organized on an open metal stand included with the set, keeping sizes accessible and identifiable on the workbench or in a service vehicle.

Key Features

• 25-piece set with 1/64-inch step increments from 1/8 inch to 1/2 inch
• 12-inch overall length provides reach into deep or confined work areas
• High-speed steel construction handles metalworking and multipurpose drilling
• Oxide coating reduces friction and heat buildup during operation
• 118-degree standard point angle for accurate starting on flat and curved metal surfaces
• Straight shank fits standard three-jaw chucks without adapters
• Open metal stand keeps bits organized and sized at a glance

Compatibility

Designed for use with standard three-jaw drill chucks accepting straight-shank bits. Suitable for metalworking and multipurpose drilling applications in inch-measurement systems.

Installation Notes

Aircraft extension drill bits are typically used by electricians, HVAC technicians, plumbers, and industrial maintenance trades for deep-reach drilling through metal substrates. Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling through steel to reduce heat and extend bit life. Inspect each bit for wear or damage before use and replace any bit showing chipped or rolled cutting edges. Follow applicable safety standards and wear appropriate eye protection during all drilling operations.
