Hertel C.402.0185 Jobber Drill Bit 1.85 Mm Hss

Product Description

The HERTEL C.402.0185 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. It features a 1.85 mm (0.0728 inch) diameter with a standard 118-degree split-point geometry and a black oxide coating that reduces friction and provides basic corrosion resistance. The straight cylindrical shank seats directly into standard drill chucks without adapters. The two-flute spiral design clears chips efficiently during through-hole and blind-hole drilling. This bit is a stock item for machine shops, maintenance departments, and trade professionals who need small-diameter precision drilling in everyday production or repair work.

This drill bit suits light-duty to medium-duty drilling applications across residential and commercial maintenance, fabrication, and assembly environments. The 1.85 mm diameter falls within the 0.0500 to 0.1000 inch decimal inch size range, making it appropriate for pilot holes, tapping prep, and small fastener clearance work. It is sold individually but requires a minimum order of 12 units, making it practical for shop stocking.

Installation Notes

This bit is installed by a machinist, maintenance technician, or trade professional using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and confirm runout is within acceptable tolerance for the application. Use appropriate cutting fluid or lubricant when drilling steel or other ferrous materials to extend tool life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
