Great idea!!! Now I can drill my hole and tap it at the same time. They work great just don't try to apply to much power to them or they might break

Very nice 3 in 1 combination tool. However, the drill tip is blunt. I could not drill a single hole in a thin aluminum sheet. Disappointing but it can be fixed by properly sharpening the drill tip on a grinder... Is this one of a kind tool defect or all of these are like that? Concept excellent, tool quality poor so the rating is 2 stars.

Excellent Drill & Tap. Drilled 18 holes in a metal walk-in freezer door panel for door hinges and handle with no issue. I have a cordless drill with two speed setting. I used a low speed setting. As long as you can hold up right, there no issue.
