27/32" Cobalt Drill Bit for Large Holes

This Drill America cobalt steel drill bit is designed for drilling 27/32" diameter holes in tough materials. The reduced 1/2" shank allows use in standard drill chucks that cannot accept larger shanks. It suits maintenance technicians and metalworkers who need to create precise, large-diameter holes without upgrading their drill motor.

Bronze Oxide Flutes Resist Wear

Surface-treated flutes with a bronze oxide finish reduce friction and improve chip evacuation during deep drilling. The 3-inch flute length and 6-inch overall length provide reach through thick workpieces. Cobalt construction maintains hardness at high temperatures. Builders needing smaller step sizes or hex-shank compatibility should select a different bit.
