## Description

EYPINS Compressed Air Angle Die Grinder 1/4" 90 Degree Mini Sander Grinder Polisher Tool for Contour Grinding,Polishing, Milling : desertcart.co.uk: DIY & Tools

Review: Worth every penny - Great value for money. It’s a bit loud compared to expensive brands but it’s been brilliant
Review: Good value for not alot of money - Pretty happy with this, have used it for probably an hour of run time so far and it's worked well. Feels smooth enough and isn't too noisy like most cheap air tools tend to be. My 200ltr compressor can keep up with the air demand it puts on it but i suspect anything smaller might struggle. For once desertcart was cheaper than ebay aswell!

## 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
