End Mill Sets, 10 Pieces Titanium Coat Carbide CNC Router Burrs End Milling Engraving Bits Drilling Hole Tool for PCB Circuit Board Plastic Fiber Wood Copper 0.8~3.175mm 1/8" Shank

These Titanium coated Carbide Milling bits perform well. Used on my drill press with a compound slide mount for my work, performed flawlessly. I didn't push it with respect to the amount of cutting I did on each pass (as I only have these bits right now, but I feel that for the money, I got the job done quickly with little to no burred edges, and minimal polishing needed. If I were using them on steel instead of Aluminum & Poly, I still believe they would have worked, but probably at a slower pace.

Perfect for using in a dremel. They fit snugly and drill perfectly

They break too easy

For the bits that I have used, they have worked well and holing up well to date.

Honestly I bought this kit only because I was sure that I would break all the bits when I was learning to work with the CNC router. I only managed to break one bit. I already made approximately 20 wooden signs with the 3 mm bit and spent 15 hours. I don't see deterioration in quality of the bit. Eventually the quality of these bits is good

Love these mill bits. They eat the wood

You must b very careful with your speed and not made for hard fast work. Worked well in the oft woods I was using.

Great bits. Sharp, can be used with a bunch of different materials. Very happy with these.
