The porous design makes the displacement smoother, ensuring that the machine does not generate heat for a long time. Inlet Air Speed Switch By controlling the amount of air intake, the rotation speed can be roughly controlled. Adapt to the fine polishing of the surface of different work objects. Idle speed: 20000 rpm, Air consumption of the windmill: 4 cfm Inlet connection: 1/4 bsp Idle speed: 20000 rpm, Air consumption of the windmill: 4 cfm Inlet connection: 1/4 bsp Regular Maintenance Put two drops of pneumatic oil before starting to work.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value for not alot of money *by A***R on 3 March 2026* Pretty happy with this, have used it for probably an hour of run time so far and it's worked well.
