## Questions & Answers

**Q: will these disks work to sand wood?**
A: i have been using the 80 grit disc on wood for three years , i use them to sculpt live edge lumber for furniture. they work great just dont over use them when they are worn out change them or they will burn the wood. they are not ment to finish sand and will gouge the wood if you are not careful.

**Q: Will these flap disk grinders fit black and decker angle grinders?**
A: Hi Steve.  These are generic and should fit any 4 1/2" angle grinders.  They work very well at removing paint and rust without removing a lot of metal

**Q: The chrome on my runner boards is bubbling and chipping. Will this work to sand the remaining chrome off and prep for Spray on bed liner on them?**
A: yes, these will sand anything, ive used them on wood,metal, paint and varnish so far, the paint and varnish clog them up pretty fast tho

**Q: Where are they made?**
A: China
