Hertel C.402.0530 Jobber Drill Bit 5.30 Mm Hss

Product Description

The HERTEL C.402.0530 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It features a 118-degree standard point angle that provides a conventional cutting geometry suited to a wide range of workpiece materials. The bit measures 5.30 mm (0.2087 inches) in diameter with an overall length of 95 mm and a flute length of 64 mm. An oxide coating reduces friction and provides mild corrosion resistance during use. With a straight-cylindrical shank and right-hand spiral flute, this drill fits standard three-jaw drill chucks found on most drill presses and hand drills.

This jobber drill is suited for general machining, maintenance, and fabrication work in shop, field, and production environments. The 5.30 mm diameter falls within the 5.00 mm to 6.00 mm size range, making it a common selection for clearance holes, pilot holes, and through-hole applications in light to medium-duty materials. It is typically used by machinists, millwrights, maintenance technicians, and fabricators working with ferrous and non-ferrous metals as well as thermoplastics.

Key Features

• 5.30 mm (0.2087 inch) diameter with 118-degree standard point angle for general-purpose entry
• High speed steel construction provides adequate hardness and toughness for common shop materials
• Oxide coating reduces friction and offers mild protection against corrosion
• Two-flute right-hand spiral design promotes chip evacuation during drilling
• Straight-cylindrical shank fits standard drill chucks without adapters
• General purpose grade suitable for maintenance, fabrication, and production use

Compatibility

Designed as a general-purpose jobber drill compatible with any drill press, CNC machining center, or hand drill equipped with a standard three-jaw chuck capable of accepting a straight-cylindrical shank in the 5.00 mm to 6.00 mm diameter range.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant for ferrous metals to extend tool life, noting that this bit does not support through-tool coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows visible damage.
