By A. Chase on April 23, 2015
Size: #3 (1/4-3/4") Verified Purchase
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.
