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.

I'd always thought these things were a gimmick. No longer! This is an awesome device for drilling through thin stock. Quick, and nice clean holes.

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