Precision Twist Drill 6001289 Wire 47 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 6001289 is a wire-gauge aircraft extension drill bit designed for precision drilling in tight-clearance and deep-reach applications. Built from high speed steel with an oxide finish, this drill bit features a 135-degree split point that is self-centering and reduces the need for a center punch on most surfaces. The 0.0785 inch cutting diameter corresponds to wire gauge size 47. With a 1 inch flute length and 6 inch overall length, it provides extended reach where standard-length bits cannot access. Two right-hand spiral flutes with a web-thinned, tapered web configuration promote clean chip evacuation and consistent cutting performance. General purpose tool performance makes it suitable for a broad range of drilling tasks encountered in aviation, HVAC, plumbing, and electrical trade work.

This drill bit is sized for wire gauge 47 at 0.0785 inch diameter and is built to NAS 907 Type B standards, making it appropriate for aircraft and aerospace applications as well as general sheet metal and light structural work. The straight-cylindrical shank at 0.0785 inch diameter fits standard drill chucks. The extended 6 inch overall length is particularly useful when drilling through structural framing, deep flanges, or stacked material layers where a jobber-length bit would not reach. Trade professionals installing electrical conduit, refrigerant line sets, or plumbing rough-in through framing members will find this bit practical for everyday extension drilling tasks.

Key Features

• Wire gauge size 47, 0.0785 inch cutting diameter for precise, repeatable hole sizing
• 135-degree split point is self-centering and reduces walking on entry
• 6 inch overall length with 1 inch flute length for extended-reach drilling
• High speed steel construction with oxide finish for durability in general purpose use
• Right-hand spiral flutes with web-thinned tapered web for efficient chip removal
• Meets NAS 907 Type B standards for aircraft-grade dimensional accuracy

Compatibility

Designed as an OEM-style replacement and general use drill bit for any standard drill chuck accepting a 0.0785 inch straight-cylindrical shank, suitable for aircraft, sheet metal, and general trade extension drilling applications.

Installation Notes

This drill bit is installed by trade professionals including electricians, HVAC technicians, and plumbers for through-material drilling in confined or deep-reach locations. Secure the straight-cylindrical shank firmly in a keyed or keyless drill chuck before use. Ensure the workpiece is clamped or secured to prevent movement during drilling. Use appropriate cutting fluid or lubrication when drilling metals to extend bit life and maintain dimensional accuracy.
