Akozon 5pcs M3-M8 Slotting Counterbore End Mill Cutter Solid Slot Countersink End Mill Drill Bit

The quality is good, they are sharp, and you can't beat the price! I've used these on aluminum, and they perform perfectly and hold their edge. The only complaint I have is that the markings are pretty light, and difficult to read. However, it's pretty obvious what size each bit is for.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

Works well. I use these with a drill press.

Why did you pick this product vs others?:Quality material great price

I haven’t started the project these were bought for.

The small diameter drill does not cut well. You need to drill a pilot hole with a regular drill of the same size.

it does what it was intended to do. cuts easy.

does a real good job of counterboring holes
