T31990 33-Piece M35 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 33-piece 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 M35 steel with 5% cobalt and can be used at much higher speeds than HSS drill bits.

This combination is excellent for drilling into very hard and tough materials like stainless steel, hardened steel, cast iron, or titanium.

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.

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