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.
