JESTUOUS Annular Cutter Set 13 pcs 3/4 Inch Weldon Shank 1-1/5 Cutting Depth and Cutting Diameter from 7/16 to 1-1/16 for Drill Press HSS Standard Kit Two Flat with 2 Pilot Pins

Use wax and oil every time. It appears this is a very good quality set of tools

This is the first set of these that I have ever bought. Decided on these over the more expensive name brand ones because I do not run a shop or anything like that and will not be using them all the time. After using the 5/8" cutter in my mag drill to drill out 55 holes with number 55 drilling as nice as the first hole I realized that I definitely made the right choice saving a lot of money buying these instead of the more expensive ones. I kept it well lubed as you are supposed to do with these. Would definitely recommend at least for someone who is not going to use them all the time.

I liked everything about them. came in a fabulous case. Works outstanding in my milling machine with /adapter and outstanding in my electromatic drill. When using them, keep the pressure on the cutter untill finished. Do not use the like you would a drill bit.

Need an improvement over twist drills for going through steel but don’t want to spend a small fortune? This will do it. Combines with a mag drill these cutters went through 1/2” steel plate in about 15 seconds. This is a huge improvement for me

The case is extremely poorly made. The foam insert is bent and looks like it was placed by a primate.I haven't used the bits yet, so word on the quality is still out.I do not like paying 150$ for a tool and have it show up with a manufacturer defect, even if its justthe box.
