Hertel 71206601 Jobber Drill Bit Wire 43 Hss Oxide

Product Description

The HERTEL 71206601 is a jobber-length drill bit sized to wire gauge 43, with a decimal diameter of 0.0890 inches. It is manufactured from high speed steel with an oxide coating to improve surface hardness and resist heat buildup during drilling. The bit features a 118-degree standard point angle, a regular spiral flute configuration, and a straight-cylindrical shank of the same diameter as the cutting end. With an overall length of 2.25 inches and a flute length of 1.25 inches, it is suited for precision drilling in light metals, plastics, and general-purpose shop materials. Machinists, tool and die workers, and maintenance technicians are the primary users.

This bit is designed for general-purpose drilling applications where small-diameter, close-tolerance holes are required. The wire size 43 dimension places it in the 0.0500 to 0.1000 inch diameter range, making it appropriate for tap-drill operations, instrument work, and fine-detail machining tasks. The right-hand cut and two-flute spiral design provide efficient chip evacuation in standard drill press and hand-drill applications. The web-thinned, tapered web configuration reduces thrust requirements at the point, which is especially useful when drilling thin stock or working with small drill presses.

Key Features

• Wire size 43 with a decimal diameter of 0.0890 inches for close-tolerance hole work
• High speed steel construction with oxide coating for heat and wear resistance
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• Regular right-hand spiral flute with two flutes for efficient chip removal
• Straight-cylindrical shank for compatibility with standard drill chucks
• Jobber length format at 2.25 inches overall for general-purpose reach and rigidity

Compatibility

Designed as a general-purpose jobber-length drill bit for use with standard drill presses, CNC machines, and hand drills accepting straight-cylindrical shanks in the 0.0890-inch diameter range.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or trained maintenance personnel familiar with small-diameter tooling. Secure the straight-cylindrical shank firmly in the drill chuck before operation to prevent runout or bit breakage. Avoid excessive feed pressure on small-diameter bits, as deflection can cause breakage. When drilling metals, use an appropriate cutting fluid to extend tool life and maintain hole quality.
