Hertel C.402.0450 Jobber Drill Bit 4.50 Mm Hss

Product Description

The HERTEL C.402.0450 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 118-degree standard point angle and an oxide coating that provides moderate lubricity and corrosion resistance during cutting operations. The bit measures 4.50 mm in diameter (0.1772 inches) with an overall length of 86 mm and a flute length of 56 mm. Its two-flute spiral design promotes chip evacuation, and the straight-cylindrical shank seats securely in standard drill chucks. This bit is used by machinists, maintenance technicians, pipefitters, and general tradespeople working with drill presses or hand-held power drills.

The C.402.0450 fits applications requiring precise, repeatable hole sizing in the 4.00 mm to 5.00 mm diameter range. It is suited for light-duty production drilling, maintenance and repair work, and general fabrication tasks. The 118-degree point angle is a standard geometry appropriate for a wide range of common workpiece materials. Right-hand cutting direction is standard for conventional drill press and handheld drill use. Coolant-through capability is not supported on this bit.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill presses or handheld power drills. Secure the straight shank fully in the chuck and verify chuck key is removed before operation. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised. Follow applicable shop safety protocols for eye protection and workpiece fixturing.
