Annular Cutters Set 9pcs 3/4 Inch Weldon Shank 1 Cutting Depth 1/2-1-1/16 Cutting Diameter Two-Flat HSS M2 Slugger Bits for Mag Drill Press with Pilot Pin & Carbide Tipped Pen

These are so awesome. Fixed my re work right up.

After running the angle grinder for 30 minutes to an hour per rivet...I tried these out and they eat through rivets within minutes.. ie on a truck that had 20 solid rivets left it took roughly 22 minutes.Wish I knew these existed sooner! 😅

As good as 100x for less

Have only used the 1/2" size so far, drilled 8 holes through 5/8" of mild steel. Cut pretty quickly, decent surface finish in the hole. There is some visible wear on the cutting edges, but over all I'm satisfied at this price point.

Hopefully the cuteness will last, but I couldn't help but try considering the price difference. These are at least one hundred dollars cheaper than name brand hole cutters.

I got this to use with my milling machine. When you need to put a large hole in a piece of steel, an annular cutter will work much better than a twist drill. These are some really heavy duty cutters. The cutters are well made, with excellent fit and finish. The cutters have a hole through the shaft for coolant. They are also nicely sharp. Whether you're using a mill or a magnetic base drill, these will certainly do the job. Highly recommend. 5 stars.

I got this with 2 bits missing and another one broken. No Missing parts in the sealed bag and no damaged pieces in the package, so it must have been shipped that way. Poor quality control. I opted for a replacement, hopefully that will go better. The bits look OK but did not try them yet.
