The Unibit3 is a pleasure to use in sheet goods. Stunningly perfect holes, quick bore, blah blah. The original and best.

Another reason I highly recommend that you buy this bit is that, unlike many Irwin tools, it is still manufactured in the USA. Irwin (formerly known as American Tool Companies) has outsourced a lot of its manufacturing to China, at a loss of quality and no reduction in price. If you care about manufacturing in countries with halfway-decent labor laws, such as the U.S., consider voting with your dollars for this excellent tool made by fairly-paid workers.

Far sharper than say HF elcheapo's, very good fit and finish. This drill bit is well worth the money paid.
