Having finally bit the bullet and procuring a mag-drill recently, I've been slowly buying annular cutters as the need arises. First few I bought were Jancy Sluggers, but I decided to give these a try as they are also highly rated and somewhat less expensive.
I like that these come with the pins without having to dig through the listings, having the buy those separately is a pain (and typically pricey).
I used the cutter I purchased to gang drill 1/2 plate (4x plates, so 2" at a time, and yes I got a 2" depth cutter). Cutter performed very well, no chips or even discoloration on any teeth even after drilling a total of 16" of steel. I did use cutting oil (and yes it's required if you're not familiar with machine tooling), nothing too specific, just the general purpose cutting oil I had on hand.
Note: If you gang drill as I did, you will have to remove the slugs from each layer as you go, the last bit of the cut always stays on the slug and that will not cut when it's spinning in the hole, this is not a fault of the cutter, there's really no way to prevent this with annular cutters.
I am quite pleased with these cutters and will be looking at more of these as I run into a need for them.

I finally got to the project that I ordered this for and put it on my mill. It looked like it had a lot of runout so I measured it. The cutter appears to be out by about 0.030-0.035”. Other than that the tool appears well made. It is sharp, appears properly hardened and cuts well but not as accurate as I need. I missed the return window or I would have tried to exchange it.

If you need to drill steel that has a flat surface, you need to buy a magnetic drill with these type of annular cutters!!!!!!! It drills through steel like butter. It is amazing you can not believe it until you see it in person. We reconstructed an electrical substation in 2 hours that would have taken 2 days before we got the drill and cutters.
Worked perfectly.2014年12月17日 - 已在美国亚马逊上发表
Only drilled two 1 1/2 inch holes in the side of an excavator bucket. Shot drilling fluid constantly. Sliced like it was cheese.
