## Questions & Answers

**Q: Will a portable 12v car tyre compressor power this? the type to pump air into tyres.**
A: Absolutely No a 12v car tyre pump would not have enough cfm to run this tool or any other air tool that are designed to run on stored air (ie: stored air in a tank) other than that the air pump needs to be producing at least 10/12 cfm to keep up with the air consumption of the air tool Hope this helps!

**Q: Suitable for woodcarving  ?**
A: Interesting question! Would the EYPINS Compressed Air Angle Die Grinder be suitable for wood carving. I personally can’t see why not, even though I personally have never tried it. I suppose it would depend on the complexity of whatever you would be carving, the tool grinds and polish’s metal with no problem at all.

**Q: Are the sanding pads screw on type**
A: Yes they are, the sanding disc’s are attached to the plastic screw in pads.

**Q: Hi, what's the minimum size compressor i.e. psi,bar rating, I would need to run this tool**
A: 9.6 min but better on 14 cfm I tried a 50 lt but found very under powered for sanders but it operates at 90 psi so 100-150 lt tank i sized up to a 150 lt much better
