Hertel 79892568 Carbide Jobber Drill Bit 17/64 in

Product Description

The HERTEL 79892568 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and non-ferrous metals, plastics, and composite materials. It features a 118-degree standard point angle with web thinning for reduced thrust and easier entry into the workpiece. The bright coating preserves the carbide substrate and provides a clean finished bore. With an overall length of 3.5 inches and a 2.125-inch flute length, this bit is sized for general-purpose jobber-length applications. It is sold as a single unit and suited for use in CNC machine tools, drill presses, and high-speed hand drilling operations.

This bit fits typical production and maintenance drilling scenarios where a straight-cylindrical shank is required. The 17/64-inch diameter (0.2656 inches decimal) and regular spiral flute geometry support consistent chip evacuation in moderate-depth holes. The C2 material grade solid carbide construction handles harder workpiece materials where high-speed steel tooling loses cutting edge integrity. Machinists, tool-and-die tradespeople, and maintenance technicians working in industrial and commercial environments are the primary users of this bit.

Key Features

• Solid carbide construction, C2 grade, for extended tool life in harder materials
• 118-degree standard point angle with web-thinned, tapered web configuration for reduced entry thrust
• Bright coating finish preserves carbide surface and minimizes built-up edge
• Regular spiral flute with 2-flute geometry for efficient chip removal
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for conventional CNC and manual drilling setups

Compatibility

Designed as a standard jobber-length drill bit with a straight-cylindrical shank for use in any drill chuck or collet system accepting a 17/64-inch straight shank.

Installation Notes

Installation is performed by machinists or maintenance tradespeople using a drill press, milling machine, or CNC machining center. Secure the shank fully in the chuck or collet before beginning any operation, and verify runout is within acceptable limits before drilling. Carbide tooling is brittle — avoid side-loading or using this bit in applications that generate lateral cutting forces. Power down and lock out the machine spindle before changing tooling.
