Description

T31989 13-Piece HSS/Cobalt Silver & Deming Drill Bit Set W/ Aluminum Case

Silver and Deming drill bits are large size drill bits with reduced shanks.

You’ll want the 13-piece T31989 HSS/Cobalt Silver & Deming Drill Bit Set for when the hole you need to drill is larger than the diameter of the chuck capacity of your drill.

These bits are made with 5% cobalt and can be used at much higher speeds than HSS drill bits.

The stepped drill bit shanks fit 1/2″ drill chucks, measure 6″ overall in length, and come in a fitted, aluminum case.

The T31989 13-piece set includes bits ranging from 17/32″ to 1″ in 1/32″ increments.

HSS (high-speed steel) has been heat treated for hardness and wear resistance, which keeps a sharp edge longer than other carbon steels.

The Grizzly Customer Service and Technical Support Teams are U.S.-based.
