Description
- Combined drill & countersink set is easy to use
- Best used in spotting & centering applications
- Made of high-speed steel with a bright finish
- 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.
- The pilot drill creates a small hole in the stock and the countersink expands the hole, leaving a small gap at the bottom of the hole that helps protect the lathe’s centers from damage when the stock is turned on it
