DeWalt's titanium drill bits have a titanium coating that provides longer life when drilling in non-ferrous metals. These bits are also suitable for drilling in wood and plastic and are ideal for commercial and residential applications. Includes sizes from 1/6 to 1/2-Inch in a plastic tough case.
Side note: if you plan to do a lot of hard steel (stainless) or titanium I would choose cobalt bits (material not brand).
*** The small bits don't snap! No breaky! ***
I've been using the DW1163 and DW1354 sets for three years, and they've gotten much more use than any bits I've used in the past (new, big house, new, big projects). With every other set of bits I've ever owned (probably really cheap bits, honestly), I'd snap one of the smallest bits in the first one or two uses. Every time. With the DeWalts, they just go and go...pilots here, pilots there, drill, drill, drill, baby!
