Hertel 79892667 Solid Carbide Jobber Drill Bit Letter P

Product Description

The HERTEL 79892667 is a solid carbide jobber-length drill bit sized to Letter P (0.3230 inches) with a 118-degree standard point angle. Built from C2-grade solid carbide with a bright finish, this bit delivers consistent hole geometry in ferrous and non-ferrous metals, plastics, and composite materials. The web-thinned, tapered web design reduces thrust at the point for cleaner entry. At 3.75 inches overall length with a 2.375-inch spiral flute, this is a right-hand cut, two-flute jobber drill suited for use in CNC machining centers, drill presses, and manual equipment requiring close-tolerance holes.

This bit is appropriate for production and maintenance machining applications in metalworking shops, tool rooms, and industrial maintenance settings. The straight-cylindrical shank fits standard drill chucks without adapters. The C2 carbide grade and high-performance designation make it a fit for harder workpiece materials where high-speed steel bits lose edge life quickly. No coolant-through capability is present, so external coolant or cutting fluid should be applied when drilling at higher feeds and speeds.

Key Features

• Solid carbide C2 grade construction for extended edge life in hard materials
• Letter P size: 0.3230 inches diameter with a tight tolerance of -0.0005 to 0.0000 inches
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright finish — no coating to alter dimensional tolerances
• Right-hand cut, regular spiral, two-flute design for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a jobber-length drill bit for use in any standard drill chuck or collet system accepting a 0.3230-inch straight-cylindrical shank, including CNC machining centers, knee mills, and drill presses.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and machining center operation. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Power down and de-energize the machine spindle completely before changing or inspecting the bit. Apply appropriate cutting fluid externally when drilling ferrous metals to manage heat and extend tool life.
