How to choose your drill?
The materials from which bits are manufactured and the finishes applied to them play a significant role in the life and performance of the bit.

Steel bits work well for boring in softwood, but dull quickly in hardwood.
High-Speed Steel (HSS) bits are harder than steel bits. They resist heat better and stay sharp longer. They can drill wood, fiberglass, PVC (polyvinyl chloride) and soft metals such as aluminum.
Cobalt bits are extremely hard and dissipate heat quickly. They're mostly used for boring in aluminum and tough metals such as stainless steel.
Black oxide-coated HSS bits have a finish designed to help resist corrosion and increase durability. They last longer than basic HSS bits and work well on a variety of materials, including metal, hardwood, softwood, PVC and fiberglass.
Titanium-coated HSS bits produce less friction. They're tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC.
Carbide-tipped bits stay sharp much longer than steel, HSS or titanium bits. They're effective for drilling tile and masonry.
