Guhring 9026010047000 Carbide Jobber Drill Bit No. 13

Product Description

The GUHRING 9026010047000 is a solid carbide jobber-length drill bit in wire gauge size No. 13, with a decimal diameter of 0.1850 inches. It features a 130-degree standard point angle and a parabolic flute geometry, both of which promote faster chip evacuation and reduced heat buildup during drilling. The bit is uncoated (bright finish) and carries a submicron carbide material grade, delivering edge retention suitable for precision hole-making in production and maintenance environments. With an overall length of 3.5000 inches and a flute-to-diameter ratio of 8xD, it is well suited for general-purpose drilling where consistent hole quality and tight tolerances are required. Machinists and tool-and-die professionals are the primary installers of this tool.

This drill bit is designed for use in materials classified under workpiece material codes K, N, and P, which correspond primarily to aluminum, non-ferrous metals, and some plastics and composites. It is appropriate for use in CNC machining centers, drill presses, and handheld power tools where a straight-cylindrical shank can be properly secured in a Jacobs-style chuck or collet. The parabolic flute design makes it particularly effective in aluminum and similar materials where chip packing is a common concern. A maximum drilling depth of 2.0890 inches (53.05 mm) applies during use.

Key Features

• Solid carbide construction with submicron material grade for extended tool life
• 130-degree standard point angle reduces thrust force at entry
• Parabolic flute geometry promotes efficient chip evacuation, especially in aluminum
• Bright (uncoated) finish suitable for use with cutting fluids or dry in non-ferrous applications
• Web-thinned, tapered web configuration improves self-centering at the drill point
• Straight-cylindrical shank fits standard drill chucks and collets without adapters
• Conforms to ANSI standards for jobber-length drill geometry

Compatibility

Designed as a jobber-length carbide drill bit for use in CNC machining centers, drill presses, and power tools equipped with a chuck or collet accepting a 0.1850-inch straight-cylindrical shank. Primary workpiece material codes K, N, and P cover aluminum, non-ferrous metals, and select plastics.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom professional. Secure the shank fully in the chuck or collet to the rated grip depth before operation, and verify runout before beginning a drilling cycle. Power down or lock out the machine spindle before changing tooling. Do not exceed the maximum drilling depth of 2.0890 inches in a single pass without appropriate peck-drilling cycles to clear chips and prevent tool breakage.
