With the drillcraft step drill, you can drill, ream, and deburr sheet metal in a single operation. Our step drills have a point angle of 118°, which makes centering in the material much easier and eliminates the need for center punching. Our range includes both straight and spiral flutes. The flute serves as a system for collecting and removing chips, enabling rapid chip removal. The precise design of our flute helps to ensure safe transport, especially with non-breaking chips.
