Guhring 9026020036600 Jobber Drill Bit No.27 Carbide Tin

Product Description

The GUHRING 9026020036600 is a solid carbide jobber length drill bit in wire gauge size No. 27, with a decimal diameter of 0.1441 inches. It features a 130-degree split point angle and a parabolic flute geometry for efficient chip evacuation. The bit is finished with a Titanium Nitride (TiN) coating that increases surface hardness and extends tool life in production drilling environments. Overall length is 3.0 inches (76.20 mm) with a flute length of 1.875 inches. This bit is installed by machinists and fabrication professionals working on precision drilling applications in light-to-medium production settings.

This drill bit is engineered for primary use in aluminum and non-ferrous materials, as well as select plastic and steel workpieces, consistent with material codes K, N, and P. The parabolic flute design and web-thinned point promote fast material removal and reduced thrust force in through-hole and blind-hole drilling operations. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. Series 2602 is designed for close-tolerance hole work where dimensional accuracy is critical, with a diameter tolerance of +0.000 to -0.018 mm.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in demanding drill cycles
• TiN coating extends tool life and reduces built-up edge when drilling aluminum and non-ferrous alloys
• 130-degree point angle reduces thrust and improves self-centering on entry
• Parabolic flute design promotes fast, clean chip evacuation and reduces heat buildup
• Web-thinned, tapered web configuration lowers cutting force at the tip
• Straight-cylindrical shank at 0.1441 inches fits standard drill chucks and collet systems
• 8xD flute-to-diameter ratio supports drilling depths up to 1.71 inches (43.31 mm)

Compatibility

Designed for use in CNC machining centers, drill presses, and hand-held power tools equipped with standard drill chucks or collet holders accepting a 0.1441-inch straight shank. Rated for aluminum, non-ferrous metals, and select thermoplastics per material codes K, N, and P.

Installation Notes

Installation and use of this drill bit is performed by machinists, tool-and-die professionals, or trained fabrication technicians. Ensure the machine spindle and workpiece are properly secured before tool engagement. Do not exceed the rated maximum drilling depth of 1.71 inches per pass without pecking cycles to clear chips and prevent bit loading. Solid carbide tooling is brittle compared to high-speed steel — avoid lateral loads or re-chucking with worn or damaged collets.
