Hertel 79892709 Solid Carbide Jobber Drill Bit 11/32 in

Product Description

The HERTEL 79892709 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. With an 11/32-inch (0.3438 inch) diameter, a 118-degree standard point angle, and a bright coating, this bit delivers clean entry and consistent bore geometry across a range of workpiece materials. The web-thinned, tapered web design reduces thrust load at the cutting tip. At 4 inches overall length with a 2.5-inch spiral flute, this is a general-purpose jobber format suited for production and maintenance drilling applications. Material grade C2 solid carbide provides the hardness and wear resistance required for harder substrates.

This drill bit is suited for use in machine shop, maintenance, and production environments where tight hole tolerances and tool longevity are priorities. The straight cylindrical shank accommodates standard drill chucks and collet holders. Right-hand cut and regular spiral geometry make it compatible with conventional drill press, CNC, and hand-held power tool setups. Typical users include machinists, tool-and-die technicians, and industrial maintenance professionals working with ferrous and non-ferrous materials.

Key Features

• Solid carbide construction rated at material grade C2 for hardness and wear resistance
• 118-degree standard point angle with web-thinned, tapered web for reduced cutting thrust
• Bright coating provides a clean, uncoated surface suitable for a broad range of materials
• 2.5-inch flute length with regular spiral geometry for efficient chip evacuation
• Straight cylindrical shank fits standard chucks and collet systems
• Right-hand cut with 2 flutes for conventional drilling operations

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks and collet holders accepting an 11/32-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operating, and verify spindle speed is appropriate for the workpiece material and bit diameter. Solid carbide tooling is brittle and should not be subjected to side-loading or interrupted cuts without appropriate setup. Always wear appropriate eye protection when operating drilling equipment.
