Hertel C.402.0760 Jobber Drill Bit 7.60mm Hss 118 Deg

Product Description

The HERTEL C.402.0760 is a high speed steel jobber-length drill bit ground to a 118-degree standard point angle. It measures 7.60 mm (0.2992 inches) in diameter with an overall length of 111 mm (4.37 inches) and a flute length of 78 mm (3.07 inches). The oxide coating provides a light surface treatment that helps reduce friction during cutting. With a straight-cylindrical shank and right-hand spiral flute geometry, this drill is designed for use in standard three-jaw chucks on drill presses, CNC machining centers, and handheld power drills. It carries a general-purpose grade classification, making it a practical everyday drilling tool for metal fabrication, maintenance, and light manufacturing work.

This drill bit is suited for general-purpose drilling in mild steel, cast iron, aluminum, and similar materials in both production and maintenance environments. The 118-degree point angle is the standard configuration for most shop drilling applications and self-centers reliably on flat and slightly curved surfaces. Machinists, maintenance technicians, and fabricators working in industrial, commercial, and light manufacturing settings will find this bit a straightforward replacement for worn or broken jobber drills in the 7.00 mm to 8.00 mm size range.

Key Features

• 7.60 mm (0.2992 inch) diameter in the 7.00 mm to 8.00 mm size range
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction for durability across a range of common work materials
• Oxide coating reduces friction and heat buildup at the cutting edge
• Right-hand cut with a two-flute spiral configuration for efficient chip evacuation
• Straight-cylindrical shank fits standard three-jaw chucks without adapters

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill press, CNC machining center, or handheld power drill equipped with a chuck compatible with a straight-cylindrical shank in the 7.00 mm to 8.00 mm diameter range.

Installation Notes

This drill bit is installed and serviced by machinists, maintenance technicians, and metalworking professionals. Always secure the shank fully in the chuck and confirm the chuck is properly tightened before operation. Ensure the workpiece is clamped or fixtured securely to prevent movement during drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain cut quality.
