Precision Twist Drill 6001270 1/16 in Hss Aircraft Drill

Product Description

The PRECISION TWIST DRILL 6001270 is a high speed steel aircraft extension drill bit designed for precision hole-making in demanding applications where standard-length bits cannot reach. Built to NAS 907 Type B standards, it features a 135-degree split point that is self-centering and eliminates the need for a center punch on most surfaces. The oxide finish provides a basic level of lubricity and corrosion resistance during use. With a 1/16-inch diameter and an overall length of 6 inches, this bit extends reach into tight or deep cavities while maintaining accurate cutting geometry. Two spiral flutes with a web-thinned, tapered web configuration clear chips efficiently during drilling.

This drill bit is suited for aerospace, HVAC, electrical, and general mechanical applications where extended reach into confined areas is required. The straight-cylindrical shank fits standard drill chucks without adapters. It performs well in right-hand rotation drills on sheet metal, aluminum, mild steel, and similar general-purpose materials. The 4xD flute-to-diameter ratio supports chip evacuation in moderately deep holes. Trade professionals including aircraft mechanics, HVAC installers, and electricians commonly reach for this style of bit when working inside panels, enclosures, or structural assemblies.

Key Features

• 135-degree split point for self-centering starts without a center punch
• 6-inch overall length provides extended reach into confined spaces
• High speed steel construction handles general-purpose drilling in metal and similar materials
• Web-thinned tapered web reduces cutting resistance and improves chip flow
• Oxide finish for basic lubricity and surface protection
• NAS 907 Type B compliant for aerospace-grade dimensional standards

Compatibility

Designed as an OEM-style extended-reach drill bit for use in standard right-hand drill chucks accepting a straight-cylindrical 1/16-inch shank, suitable for general-purpose drilling applications across trade disciplines.

Installation Notes

Installation and use of this drill bit should be performed by qualified trade professionals familiar with drilling operations and applicable safety standards. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning. Always wear appropriate eye protection when drilling metal. Use cutting fluid or lubrication when drilling harder materials to extend bit life and reduce heat buildup.
