Precision Twist Drill 6001436 Hss Aircraft Extension Drill

Product Description

The PRECISION TWIST DRILL 6001436 is a No. 5 wire size (0.2055 inches diameter) high speed steel aircraft extension drill bit designed for deep-reach drilling applications where a standard-length bit cannot access the work area. The 135-degree split point is self-centering and eliminates the need for a center punch on most materials, reducing setup time and improving hole accuracy. The oxide finish provides a measure of lubricity and corrosion resistance during cutting. With a 12-inch overall length and a 2.5-inch spiral flute, this bit delivers chip clearance and cutting performance in tight or extended-reach situations. It is manufactured to NAS 907 Type B standards.

This drill bit is suited for aerospace, sheet metal, and general industrial applications where extended reach is required to drill through structural panels, frames, or assemblies. The straight-cylindrical shank (0.2055 inches diameter) seats in standard drill chucks without adapter sleeves. The two-flute, right-hand cutting spiral geometry and tapered web configuration with web thinning make it effective in both hand-held drills and drill presses. General purpose tool performance rating makes it appropriate for a wide range of ferrous and non-ferrous materials.

Key Features

• No. 5 wire size — 0.2055 inches diameter for precise fit in tight-tolerance applications
• 135-degree split point with web thinning for self-centering entry without a center punch
• 12-inch overall length for extended-reach drilling in structural assemblies
• High speed steel construction with oxide finish for lubricity and wear resistance
• NAS 907 Type B standard compliance for aerospace-grade dimensional requirements
• Two-flute right-hand spiral with tapered web for efficient chip evacuation

Compatibility

Designed as a general-purpose aircraft extension drill bit conforming to NAS 907 Type B, suitable for use in standard drill chucks accepting a 0.2055-inch straight-cylindrical shank across drill press and hand-held drill applications.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist, aircraft mechanic, or trained technician familiar with metal drilling procedures. Secure the workpiece and verify chuck grip on the straight shank before operating. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole finish. Inspect the cutting edges and point for wear or damage before each use and remove the bit from service if chipping or dulling is observed.
