End Mill Sets, Tungsten Steel CNC Router Burrs End Milling Engraving Bits Drilling Hole Tool for PCB Circuit Board, Plastic, Fiber, Wood, Copper 0.5~3.175mm Set of 12

When I first received this product I was extremely pleased and excited. The finish on the end mills was impressive and it just screamed quality. The plastic storage bins is a plus. While not certain if the color coding is standard it does help develope a sense of order and recognition of the sizes. I did have a slight issue with a couple od the smaller bits, but a quick message to seller and they solved the problem almost instantaneouly and to my grest satisfaction. I would not hestiate in referring people to this company or product. Hope to do budinrrd eioth the sgsin.

Hey, I broke a couple cause I didn't know what I was doing! Great cause these were CHEAP! But, once I knew how to work my CNC machine the ones I didn't break were great for wood, pcb, and other stiff non melty things. Plastic melted and stopped up the bit. I engraved some aluminum on a super, and I mean super slow speed, would not recommend these for metal but otherwise they are great!

I used these in my CNC machine. The bits worked well however they are very small and did not stand up to hard wood. That was probably poor feed rate so I can't blame that on the bits. For very fine detailed carving, these bits work great

These sets have a few advantages over the competitors.-Plastic stopper that prevents the bit from dropping into a large dremel chuck.-smaller sizes(better variety of bits)-the smaller bits are shorter on the working end. This allows less horizontal shearing forces and is more resilient to breaking. It will still break but it’s a bit better.-Costs less

These work extremely well in MDF. Small sizes are very fragile so be careful and do not drop them. You will break the smaller ones. All it takes is a little bit too much speed or too deep of a cut/pass and it will disappear!

The 1mm bit did OK on plywood, nice lines, but broke half way in a cnc project. I was cutting 2mm depth at 200 step. Broke the bit about 8 minutes in. I guess I will try 100.

I bought them to try them to make my wood projects and I loved them impressive with the result I recommend them and I would buy them again …..
