cheaper than anywhere I could find them and they are high quality

I have been wanting to get an annular cutter set for a very long time. Most annular cutter sets are intended for use in mag drills. I do not have a mag drill but I do have a vertical mill. I put the annular cutter into a 3/4" collet (using 3/4" cutter), set the rpm's to roughly 100 and started feeding into a piece of 3/16" tube steel. The cutter went through like hot butter, the biggest issue was the need to stop the process to break the long burrs that started becoming dangerous.Since I was using a 3/4" collet and the mill, I did not have a spring for the point, the slug still came out of the cutter with very little effort. Eventually I may make a tool for inside the collet to use the plunger to remove the plug. But overall, I will never go back to using a drill bit again. The entry side was the cleanest I have ever had and the exit side left almost no burrs. The pictures attached are immediately after the cut without any processing to remove the burrs.

Excellent cutters, they cut smooth and clean.

Perfect just as advertised quality product works very well.

Super clean cuts with mag drill. Shocked to have zero burrs on top and underside of holes through 3/8 steel. Stayed cooling when drilling. Staying super sharp after 20 holes

This annular cutting set has paid for itself over and over. As a professional welder and metal fabricator, I rely on precision and efficiency, and these cutters have delivered both without fail. Whether I'm drilling through thick metal for custom trailer builds or fabricating complex structures, these cutters have proven absolutely essential.I've put them through their paces on heavy steel, and they cut clean, precise holes every time. No overheating, no dulling out prematurely—just consistent, high-quality performance. For the price, they’ve far exceeded my expectations.If you’re serious about metal fabrication, this set is a must-have. It’s durable, dependable, and has become an irreplaceable part of my shop.

Bits cut good. 5/8 punched 42 holes and never slowed down. Have not used another bit out of the set but I hope they all work like the one.
