T31990 33 Pc. HSS/Cobalt Silver & Deming Drill Bit Set W/ Aluminum Case
Silver and Deming drill bits are large size drill bits with reduced shanks.
These bits are made with 5% cobalt and can be used at much higher speeds than HSS drill bits.
You’ll want the 33 piece T31990 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 stepped drill bit shanks fit 1/2" drill chucks, measure 6" overall in length, and come in a fitted, aluminum case.
The T31990 33 piece set includes bits ranging from 33/64" to 1" in 1/64" increments.
