Hertel 79892287 Solid Carbide Jobber Drill Bit No. 16

Product Description

The HERTEL 79892287 is a solid carbide jobber-length drill bit in No. 16 wire size, measuring 0.1770 inches in diameter. Built from C2-grade solid carbide with a bright (uncoated) finish, it delivers the hardness and wear resistance needed for precision drilling in ferrous and non-ferrous materials. The standard 118-degree split point with web thinning reduces thrust and improves centering at entry. Overall length is 2.75 inches, with a 1.625-inch spiral flute length and a straight-cylindrical shank. This is a high-performance grade bit suited for production and maintenance drilling where dimensional accuracy and tool life are the priority.

This bit is used in light-to-medium drilling applications across metalworking, mechanical maintenance, and fabrication environments. The right-hand, regular spiral flute geometry suits drilling in steel, aluminum, brass, and similar materials on drill presses, CNC machining centers, and handheld power tools. Its straight-cylindrical shank fits standard Jacobs-style and keyless chucks. The web-thinned tapered web configuration reduces cutting force, making it well-suited for through-hole drilling in thin stock or sheet metal work.

Key Features

• Solid carbide construction, C2 material grade, for extended tool life in demanding drilling operations
• No. 16 wire size, 0.1770-inch diameter, with a tight tolerance of -0.0005 to 0.0000 inches
• 118-degree standard point angle with web thinning for reduced entry thrust and accurate self-starting
• Bright finish — no coating — for use where coating buildup in the flute is a concern
• Regular right-hand spiral flute, 2-flute design, 1.625-inch flute length for efficient chip evacuation
• Straight-cylindrical shank, 0.1770 inches, compatible with standard drill chucks

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for applications requiring a No. 16 wire-size, 0.1770-inch solid carbide bit with a straight-cylindrical shank and 118-degree point.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Secure the shank fully in the chuck and verify runout before drilling. Do not exceed the recommended RPM and feed rate for the workpiece material and bit diameter. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and can fracture if subjected to lateral loading or impact.
