Hertel 74460023 Solid Carbide Jobber Drill Bit 7 Mm

Product Description

The HERTEL 74460023 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. Built to a 7 mm (0.2756 inch) diameter with a 118-degree standard point angle, this bit delivers accurate, repeatable results in metal, composite, and engineered materials. The bright coating preserves the natural carbide finish without adding thermal treatment. Web-thinned geometry reduces thrust force at entry, and the tapered web configuration improves chip evacuation. This bit is installed by machinists, tool and die technicians, and maintenance professionals working with CNC machines, drill presses, and hand-held power tools.

The 74460023 suits general-purpose drilling applications in shops, production environments, and maintenance operations where carbide-grade tooling is required over high-speed steel. The 2-flute regular spiral flute design handles a wide range of workpiece materials. With a straight-cylindrical shank at 0.2756 inches, it seats directly in standard keyless or keyed drill chucks and collet-style tool holders without adapters in most setups. This bit is rated for right-hand cutting direction and falls in the C2 material grade classification, appropriate for general-purpose carbide drilling operations.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree standard point angle for general-purpose drilling
• Web-thinned, tapered web design reduces entry thrust and improves chip flow
• Bright finish - no coating interference with dimensional tolerance
• Diameter tolerance of -0.0005 to 0.0000 inches for tight, consistent hole sizing
• Right-hand, 2-flute regular spiral flute for broad material compatibility

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and collet holders accepting a 0.2756-inch straight-cylindrical shank; suitable for CNC machining centers, drill presses, and portable drilling equipment requiring 7 mm carbide tooling in the C2 grade range.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before engaging the workpiece. Power down and lock out the machine before changing tooling. Carbide is brittle - avoid side loading, interrupted cuts without proper feed rate management, or dropping the bit on hard surfaces.
