I am very happy with this item.I have ordered several of these bits and have been happy with all of them.This bit is sharp and dimensions are correct.I have used this bit for engraving lettering in 6061 aluminum with great success with only a light spray of WD-40 as lubricant. Just make sure you take it slow and observe proper chip load for the material you're cutting and these bits will perform well and last a long time.I've switched over to this brand almost exclusively. The only thing I'd change is that I'd love to see them make tool database files available for importing into major cad software like some of their competitors.Overall I definitely recommend these bits. They are really as good as some of the name brands at a fraction of the price.

I was leery of buying this bit due to the length of the 1/16” portion. It just seemed like it might snap off easily. But I had to have a bit with that reach so I bought it. I have been very pleasantly surprised with the strength of the bit and its performance. I purchased another long reach 1/8” bit by SharPro and am very pleased with it as well.

I have used it on several projects and the quality is very good. It is very sharp and cuts very nicely through different materials. Good value for the money.

This is an incredibly sharp and seemingly durable downcut spiral CNC bit. I used this for some simple engraving on a standard 3018-Pro. It works really well in softwoods and plastic/resin, and it hasn’t given me any issues. I appreciate that it comes in its own storage case since my CNC bits are so small - it’s easier to keep track of them if they’re in separate, labeled cases.Overall, for an entry-level CNC downcut bit, this is an excellent option.

This little thing is pretty sick. I didn't want to use it; it has some cool colors lol! It has a plastic protective cover for the end and a pretty cool little holding case. It's easy to attach to my router! It works and cuts super well! Just a little smaller than I was thinking... However, that is my fault for not paying attention lol!
