HQMaster CNC Engraving Bits, Bit Cutter 10 Pack 0.1mm Tip Tungsten Steel Titanium Coated Flat Bottom Sharp Cutting Router Rotary Tool Set for PCB PVC Wood Acrylic Aluminum

Havent used the product yet, but looks very good

I expect bits to wear out. These bits last longer than bits that I paid 15 times the price for I will be ordering again!

I used these bits with wood and they seem to work just fine. I wants pushing them hard with a feed rate of 10 IPM. Once I switched over to the real part in Aluminum the bits were breaking. I even slowed by feed to 1 IPM and it still snapped off the tips. With closer inspection the taper cuts on the bits are very poorly cut. Surprising because I have had pretty good luck with the HQMaster Flat Nose Endmills.

Very good

Excelente calidad.

Pros: Good value for a pack of cheap bits. They're sharp. So sharp that i needled my fingertips the first time i tried to get one out of the box. Be careful.Cons: DON'T try to do fine detailing for inlays in anything harder than mahogany or white pine with these. Those tiny tiny tips on these things break every time and you lose about 1 mm depth, so some parts of the inlay won't fit properly. you will spoil the job... If all you need to do is engrave enough depth to do an epoxy fill, these would work just fine. It's not a feed rate problem because I dialed back the feed rate to a crawl even at risk of rubbing/overheating but they still break.

Justo lo que necesitaba para mis trabajos en router.

Ordered based on reviews. Tips continued to break and ruined my project.
