Excellent bit for adding breaker box conduit holes
This bit was nice and sharp on arrival. It drilled smoothly through the side of my electrical box with zero binding and made the perfect size smooth-edged hole for my 3/4" conduit connectors. Note that I used medium speed and applied 3-in-1 machine oil to the edges of the cutting blades every 30 seconds or so to help dissipate the heat which helps prolong the life of my metal bits. Another nice feature is the shank has flat sides so it won't slip in the drill.

Best step drill I have ever owned.
This step drill works extremely well. Compared to inexpensive ones like the ones that you get from Harbor freight, this step drill is not even in the same category. It works super well. Would definitely buy it again.

Keep em in stock and I’ll keep buying!
Product is exactly as described. Same as if you bought it from Home Depot but only much easier on the wallet than the price in store. As long as the price beats Home Depot - I’ll keep buying!

For thin stock, this is a delight to use and a MUST-HAVE tool.
This looked like a version of the classic Unibit, a proven means to make clean holes in thin stock such as plastic or sheet metal. Somehow Milwaukee kicked it up a notch. The way this bit so evenly cuts material is a delight. I've got a hunch there is some exceptional geometry and metallurgy at work here. If you occasionally need large holes in thin stock, this is a MUST-HAVE tool. Tip: Rotate it at low speed and don't add more speed unless you really need it.

Quality bit - decent price
Based on the options available from Amazon and other local vendors I decided to to with this one. It works well, far better than the cheaper options. If you plan on using it more than once, then just buy a quality bit the first time. (Such as this) You'll save money in the long run, not to mention your saving yourself from the added frustration of a junk bit. *Use oil if you want it to last.
