Hertel 74460080 Jobber Drill Bit 10.5mm Carbide 118 Deg

Product Description

The HERTEL 74460080 is a jobber-length drill bit designed for precision drilling in metal, composites, and other hard materials. Built from solid carbide with a bright finish, this bit delivers consistent performance in general-purpose production environments. It measures 10.5 mm (0.4134 inches) in diameter with an overall length of 4.5 inches and a flute length of 2.875 inches. The 118-degree standard point angle suits a wide range of material types. Web thinning reduces thrust requirements at entry, and the tapered web configuration improves chip evacuation during drilling operations. It is typically installed and used by machinists, tool-and-die professionals, and maintenance technicians.

This bit is suited for general-purpose drilling in shop and field environments where solid carbide tooling is specified. The straight-cylindrical shank fits standard drill chucks and collet holders. With a two-flute spiral configuration and right-hand cut, it is used in CNC machining centers, drill presses, and hand-held power tools requiring precise hole sizing in the 0.4000 to 0.5000 inch (10.00 to 12.50 mm) size range. The bright coating is uncoated-bright, meaning no additional thermal or lubricious coating is applied, making it well suited for materials sensitive to coating contamination.

Key Features

• Solid carbide construction rated to material grade C2 for hardness and wear resistance
• 118-degree standard drill point angle for general-purpose entry across common materials
• Bright finish with no additional coating for clean, contamination-free drilling
• Web-thinned with tapered web configuration to reduce entry thrust and improve chip flow
• Right-hand cut, two-flute spiral design compatible with standard drilling equipment
• Diameter tolerance held to -0.0005 to 0.0000 inches for consistent hole sizing

Compatibility

Designed as a general-purpose jobber-length drill bit fitting standard straight-shank drill chucks and collet systems in the 10.00 to 12.50 mm size range.

Installation Notes

This drill bit is installed by machinists and maintenance technicians in standard three-jaw chucks or collet holders. Ensure the machine spindle is fully stopped and the chuck or collet is properly tightened before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, noting that this bit does not support coolant-through delivery. Inspect the drill point for chipping or wear before each use, as carbide tooling is brittle and susceptible to damage from improper handling or interrupted cuts.
