Hertel C.402.0620 Jobber Drill Bit 6.20mm Hss

Product Description

The HERTEL C.402.0620 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Ground from high speed steel and finished with an oxide coating, it measures 6.20 mm (0.2441 inches) in diameter with a 118-degree standard point angle that self-centers on most materials without a pilot hole. Overall length is 102 mm with a 70 mm flute length, giving it the reach-to-rigidity ratio expected in production and maintenance drilling. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. This bit is a single-piece, individually packaged unit suited for machinists, maintenance technicians, and fabricators.

The C.402.0620 fits standard drill chucks and is appropriate for use in bench drills, drill presses, and hand-held electric drills in both shop and field environments. Its straight-cylindrical shank seats securely in keyless or keyed chucks across the 6 mm to 7 mm size range. The general-purpose grade makes it a practical stock item for maintenance shops, HVAC fabrication benches, and plumbing or electrical rough-in work where pilot holes and knockout drilling are routine tasks.

Installation Notes

Installation and use of this drill bit should follow standard machine-shop and hand-tool safety practices. Secure the workpiece before drilling and confirm chuck jaws are fully tightened before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
