H5931 4-Piece 82° Center Drill Set

The H5931 Center drills consist of a pilot drill on one side and a countersink on the other.

These center drills are used to cut holes in the center of a piece of stock on a metalworking lathe.

They all have a live center angle of 82° which is common for use with flat head screws.

The double ended H5930 HSS Center Drills are precision ground and includes sizes 1-4.

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.
