● High speed steel
● Single-fluted design eliminates skidding and makes for easier resharpening.
● Laser-etched hole sizes are easy-to-read and permanent.
● Anti-skid tip eliminates the need for center punching or pilot hole drilling for most sizes.
● Drill multiple-size holes in thin sections of metal, plastic and wood using a single bit
● Works in most metals (steel, brass, aluminum, copper),as well as in plastic and wood
