These high-speed step drill bits feature a titanium coating so they run cool and are made out of high-speed steel for a long service life. The drill bits automatically deburr holes as you drill and the two-flute design provides faster, smoother cutting. Whether drilling in plastic, metal, or wood, these drill bits cut great every time.
