Hertel 79892824 Solid Carbide Jobber Drill Bit 15/32 in

Product Description

The HERTEL 79892824 is a solid carbide jobber-length drill bit designed for precision drilling in demanding shop and field applications. Ground to a 118-degree standard point angle with a web-thinned, tapered web configuration, it reduces entry force and promotes clean hole starts. The bright (uncoated) finish suits use in a wide range of workpiece materials where coating buildup is a concern. At 4.75 inches overall length with a 3-inch flute, this bit delivers the reach and chip-clearance geometry machinists and tool-and-die professionals expect from a high-performance carbide drill.

This drill bit is suited for precision machining operations on CNC machining centers, drill presses, and manual mills where solid carbide tooling is specified. The 15/32-inch diameter and straight cylindrical shank allow direct chuck mounting without adapters. It is appropriate for production shops, maintenance facilities, and industrial contractors drilling ferrous and non-ferrous metals, composites, and other hard materials requiring carbide-grade tooling rather than high-speed steel. Material Grade C2 positions it for general-purpose carbide drilling applications.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and clean entry
• Bright finish suitable for dry cutting and applications where coating interaction is undesirable
• 2-flute regular spiral geometry promotes efficient chip evacuation in through-hole drilling
• Straight cylindrical shank for direct chuck mounting without sleeves or adapters
• Diameter tolerance of -0.0005 to 0.0000 inches ensures close-tolerance hole sizing

Compatibility

Designed as a jobber-length solid carbide drill bit for use in standard drill chucks and collet systems accepting a 15/32-inch straight cylindrical shank. Suitable for CNC and manual spindles specifying C2-grade carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional. Secure the shank fully in a precision drill chuck or collet and verify runout before cutting. Power down and lock out the spindle before changing or inspecting tooling. Solid carbide is brittle — avoid side loads, interrupted cuts without appropriate feeds and speeds, and contact with hard surfaces that can chip the cutting edges.
