First off, they are a little fragile in the sense that you have to pay attention to what you're doing (mind your plunge rates and feed speeds). I did break a few but it was my fault. When used properly, they hold up great. Once dialed in, I have yet to have one fail in operation (2+ hour runs). These have been great for etching PC boards. I haven't used them for anything else but for PCBs, they have changed the game for me. I have pretty much shelved my ferric chloride for good!

I use these for making 1-off PCB's, and they do a great job. I can drill and mill with this bit, and each bit lasts me about 2 square feet of facing on average. I always have a couple sets on hand. I've used other brands and types, but you can't beat these for the money.

I expected these to be super fragile with them being so tiny but I do a lot of detailed work and i thought the price is great, so I can afford to break a few. With a collet reducer these fit perfect and if you go slow and hold the router right, haven't broke one yet.. I'm so impressed.

I ordered these to cut slots in a mandolin fret board. The price was significantly less than cutters offered by specialized suppliers. Coming in packs of 10, I expected to perhaps break a few to writing off the entire purchase as a bad experience. Well, one bit completed 28 slots without fail and with every expectation they'll continue cutting.Cut details are; 24000 rpm, 5 ipm, 0.007" cut depth per pass. Total cut depth is 0.080". Material is walnut.

These bits are great for inlay work. I've used on hardwood and mother-of-pearl. I use them on my cnc and slow feed rates and light cuts gave great results.

I bought these to cut fret slots with my CNC machine. I was nervous about the small diameter. But, I was very pleased with the results. 12k RPM at 60in/m with a depth per pass of .005 was a successful combination. My machine cut 42 slots in ~26m. The slots were very clean and only required light surface sanding. Highly recommended.

Purchased to engrave small letters 1.2mm deep in Birch plywood using my Desktop 3040T CNC, instead of using a v-bit. Did the job required, with clean precise cuts.Would by more, but 10 looks like a lifetime supply, unless I need to use them in Aluminum.
