Great New Design
[This review was collected as part of a promotion.] My Husband loves this New Step down Bit. The fact that it does it all with One bit without switching them out makes drilling a whole so much easier. The Hex head makes it better for the drill to bite. Milwaukee makes the Best Tools!!

Durable and fast
[This review was collected as part of a promotion.] This drill bit is durable and makes perfect holes, it also feels very high quality. I like how many sizes its able to make and it fit in my drill well. It was easy to use and made holes pretty fast when I was using it on metal.

"Awesome Tool"
[This review was collected as part of a promotion.] We love making our own barbecue grills. So to day we are using a Mike Tool Shockwave Impact Bit size 7/8"- 1 1/8 inch. We love this bit to help us drill through metal for putting the hinges on. It is a great bit and gets the work done 2x faster than a normal bit. Made out of titanium, and lasts up to 5x the life.

This bit works very well, the tip starts and drill very easily and step part of the bit cuts well. It works good with the impact driver but is slower than using it with a regular none impact drill. It does not take a lot of pressure to make it drill. The 2 cutting edges make it cut faster than the style of bit with only one cutting edge but also make it a little more prone to grabbing and vibration. I wish that they would have put more size markings on the bit, there are only 2 markings one for 7/8 and one for 1 1/8, and it looks as though they may wear off quickly. It will drill about 1/16 inch thick material before hitting the next step. Basically I like this tool and it works well, but it does not seem to be any better than my discount store bits at a fraction of the price, it might last longer but only time will tell.

This is definitely a commercial quality step bit. This Shockwave Impact duty step bit is perfect for drilling larger sized holes in steel or a variety of other materials. I did my testing with 1/8 steel. This impact bit really does drill holes twice as fast! I drilled a variety of different sized holes with both an impact and regular drill. The smaller sized holes seem a bit sloppy but that could be user error. I would recommend the impact for the larger sized holes as the drill did try to twist on me. After drilling multiple different sized holes in different materials, the bit never got hot or showed any signs of wear. You can feel the drill drop when you get to the next bigger increment on the step bit and it seems that the larger the hole gets, the faster the drilling process goes. I foresee this bit lasting a long time being made of titanium and that it seems to self cool itself.
