Hertel 79892733 Solid Carbide Jobber Drill Bit 3/8 in

Product Description

The HERTEL 79892733 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. Built to a C2 carbide material grade, it delivers the hardness and edge retention needed for high-performance drilling in ferrous and non-ferrous metals, composites, and plastics. The 118-degree standard point angle provides fast engagement and accurate starting without center punching. With a bright (uncoated) finish and web-thinned, tapered web configuration, this bit reduces thrust requirements and improves chip evacuation. Machinists, tool and die workers, and fabricators reach for this bit when running production or precision work in a mill or drill press.

The 79892733 fits standard jobber-length applications where a 3/8-inch diameter hole is required. The straight-cylindrical shank seats securely in standard 3-jaw chucks and collet systems without slipping under load. The 2-3/4-inch flute length accommodates typical through-hole and blind-hole depths encountered in general metalworking and fabrication. Right-hand spiral flute geometry promotes efficient chip removal during conventional drilling operations. This bit is suited for job shops, maintenance departments, and production environments running short-to-medium run drilling tasks.

Key Features

• Solid carbide C2 grade construction for superior hardness and wear resistance
• 118-degree standard point angle for fast, accurate engagement
• Web-thinned tapered web reduces thrust and improves chip flow
• Bright finish compatible with a wide range of workpiece materials
• 2-flute right-hand spiral design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard chucks and collet holders

Compatibility

Designed as an OEM-style jobber-length drill bit for use in any drill press, milling machine, or hand drill equipped with a chuck or collet accepting a 3/8-inch straight-cylindrical shank.

Installation Notes

Machinists and fabricators should ensure the shank is fully seated and the chuck is tightened securely before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter before drilling. Solid carbide bits are brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling ferrous metals to extend tool life.
