## Questions & Answers

**Q: will these cut aluminum?**
A: The machine can engrave aluminum as far as cutting it it would take a very long time depending on the hardness.  To engrave I would set the passing depth at  0.5mm and the feed rate between 150 and 300 mm/min, spindle speed between 300 and 500 rpm. Aim a cooling fan at the work piece and keep a vacuum handy.

**Q: Can It engrave on copper?**
A: It's possible, but I wouldn't recommend it. Engraving on metal, even one as soft as copper, would dull the bits quickly.

**Q: Why is amazon shipping from Baltimore to Kentucky and back to baltimore?**
A: All 2 day air packages go to the hub in Kentucky first.  You could ship something 2 day air to your next door neighbor and it will go to Kentucky first. Crazy, right?

**Q: Are these upcut or downcut?  Can this vital piece of information be added to your product specs please?**
A: I believe they are Burrs and neither upcut or downcut however, they have an appearance of being upcut. Although I have them, I have not used them yet.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great cnc bits
*by L***  on January 25, 2025*

Very pleased with this, for my cnc and they work great , cut great

### ⭐⭐⭐⭐⭐ Affordable and effective
*by C***R on August 16, 2019*

So far these have worked great for cutting wood. Just be sure to get your feeds and speeds right. Run them too fast and you break them, run them too slow and you create friction which heats them up until the either break our wear out very fast. Even the most expensive endmills in the world can be destroyed by operator error. I got good results cutting hardwood with the 1.4mm bit using SFM: 141, chipload of .005, and a depth of cut of .0157 (4mm). I would not probably not recommend cutting metal with these, but I have not tried it yet.

### ⭐⭐⭐⭐ A little brittle, but they work well.
*by Z***O on August 27, 2023*

The small ones are likely to break, but that's kind of the nature of working with bits this small. They all cut well in my CNC, tho so I would still recommend them.
