Hertel 79892204 Carbide Jobber Drill Bit 5/32 Inch

Product Description

The HERTEL 79892204 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. Built from C2-grade solid carbide with a bright finish coating, this bit delivers consistent cutting performance and dimensional accuracy. It features a 118-degree standard point angle, two spiral flutes with a regular helix, and a web-thinned tapered web configuration that reduces thrust and improves chip evacuation. The 5/32-inch diameter is held to a tight tolerance of -0.0005 to 0.0000 inches. Licensed machinists, tool-and-die techs, and maintenance professionals working with metals and hard plastics rely on this type of solid carbide tooling for precision hole quality.

This jobber-length drill bit is suited for general-purpose production and maintenance drilling in metalworking environments, machine shops, and industrial maintenance applications. The 2.5-inch overall length and 1.375-inch flute length make it appropriate for standard depth drilling operations on drill presses, CNC machines, and hand-held power drills where a straight-cylindrical shank is compatible with the tool holder. No coolant-through capability is present, so this bit is intended for conventional dry or flood-coolant setups at the exterior.

Key Features

• Solid carbide C2-grade construction for hardness and wear resistance in ferrous and non-ferrous materials
• 118-degree standard point angle for general-purpose drilling with clean entry
• Web-thinned tapered web reduces drilling thrust and improves chip flow
• Bright finish coating provides a consistent, non-coated surface for close tolerance inspection
• Right-hand cut, two-flute regular spiral design for efficient chip evacuation
• Tight diameter tolerance of -0.0005 to 0.0000 inches ensures accurate hole sizing

Compatibility

Designed as an OEM-style solid carbide jobber drill bit compatible with standard straight-cylindrical shank tool holders and chucks accepting a 5/32-inch shank diameter.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or maintenance technicians familiar with proper speeds and feeds for carbide tooling. Ensure the drill chuck or collet is clean and properly tightened before use, as carbide is brittle and sensitive to runout or side loading. Do not use this bit as a reamer or apply lateral force during drilling. Follow the machine manufacturer guidelines and applicable workplace safety codes when operating drilling equipment.
