This is GREAT for drilling holes in thin metal and probably other materials. I don't think it would be good for any thick material because you would just have a cone hole. I had seen reviews on some of the cheaper tools to get a good one like this and I'm glad I paid a little more for it - sometimes the quality is very important in tools. I've only used it a few times now but it seems durable so far. I love this tool.

A very nice bit, rips through wood or metal with no problems and very little fight.

Made quick work for the boat trailer upgrades I'm doing. Drilling a pilot hole first will definitely help. Most bits slip in my drill. But this one held on like a champ.

Pricey but does a great job. Stays sharp and saves precious time. There's nothing worse than humping a drill with a dull bit at the end of the day.

Of the many brands I've used for work, these Milwaukee ones last the longest. As with any bit, drilling through stainless steel will dull them quicker than drilling through mild steel. Also, as with any bit, don't overheat them and they will last longer.

Really worth e-v-e-r-y p-e-n-n-y...time-saving and sheer ease. That said the cost is high (at least for me right now) so I borrowed a friend's and have had drill bit envy ever since.
