Three step drill bits cover 28 hole sizes from 1/8" to 3/4", replacing a rack of twist bits and cutting down tool changes. Titanium-coated high-speed steel reduces friction and keeps the edges sharp longer.

A 118° split point centers itself without walking, and the 2-flute design clears chips and heat for clean, burr-free holes. Drill and enlarge holes in sheet metal, aluminum, copper, plastic, fiberglass and light wood. The 1/4" quick-change hex shank fits drills and impact drivers, and the set comes in a fabric pouch.
