Drill America 1-7/16in Cobalt Drill Bit
This Drill America cobalt steel bit handles 1-7/16in holes with a reduced 1/2in shank that fits standard chucks. Bronze oxide coating and surface-treated flutes resist heat and improve chip evacuation in tough alloys. The 6in overall length and 3in flute reach deep work without a special holder.
Best for large holes in hard steel and iron
Machinists and maintenance technicians drilling 1.4375in diameter holes in stainless or high-carbon steel will value the cobalt edge life. Builders needing smaller diameters, faster change systems, or non-metal materials should look at other tooling.
Highlights

Questions about this item
What chuck size do I need to hold the 1/2 in reduced shank?
A 1/2 in chuck or larger will grip the reduced shank securely.
Will the 1.4375 in cutting diameter fit through a standard 1/2 in drill press spindle?
The spindle only needs to accept the 1/2 in shank; the larger cutting diameter clears the workpiece without contacting the spindle.
