MACHINING Center Drills

WWG1DBE5

Center Drills Center drills consist of a pilot drill and a countersink and are used to create holes at the center of a piece of stock so it can be turned between centers on a lathe in metalworking applications. Drills with a radius tip have a tapered flute that allows them to create more accurate holes than other styles of center drills. Center drills with a plain tip are suitable for creating center holes in a piece of stock to prepare it for turning between centers on a lathe. Jig-bore tips have a flat on the shank for securing the drill to a jig borer machine with a set screw. They create holes at the center of a piece of stock so it can be turned between centers on a lathe. Bell tip create a hole at the center of a piece of stock so it can be turned between centers on a lathe.

High-Speed Steel—Provide good wear resistance in a wide range of machining applications.

Cobalt Steel—Provide good wear resistance when machining hard materials at high speeds and harder than high-speed steel center drills.

Solid Carbide—Provide excellent wear resistance when machining the toughest materials, such as cast iron and stainless steel.
