## Questions & Answers

**Q: will it work on a hitachi 4 1/2” grinder?**
A: I don’t know about the Hitachi 4 1/2 , but it works on a Bosch 5 “ and a Makita 7” most likely it will work on the Hitachi. I had to purchase a universal nut with centering washer at Home Depot or Lowe’s

**Q: Is this disc compatible with a galaxia angle grinder?**
A: Yes, it will work. It comes with a bushing to fit a five-eights arbor. Make sure the disc isn't touching the gaurd before turning on your tool. If it does touch, remove the gaurd. These tools can be dangerous, use a full face mask, clamp your wood firmly to a stable surface, and hold the grinder firmly with two hands. It's a great tool once you get used to it. I prefer these to the expensive arbortech planers.

**Q: Will this sharpen a carbide tip**
A: NO, this tool is for  wood sculpting,  for carbide tips, see, on amazon,3 Inch Flat Shape Diamond Grinding Wheel 150 Grit 1/2" Bore for Grinder Cutter Grinding Metal Hard Alloy Glass Tiles Ceramics (78x12.7x10x10mm)  $20.00 plus shipping

**Q: Are these compatible w/ a Dewalt die grinder?**
A: The Shaping Wheels will fit most Dewalt '4-1/2" Angle Grinders', however the Kutzall 1/4" Shaft Burrs will fit most Dewalt Die Grinders.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality wood shaping wheel for handheld grinders.
*by P***  on August 29, 2025*

This was perfect for shaping wood. Very aggressive grit so it works fast yet still leaves a decent finish. You definitely want to use your side handle and guard. Don’t ask.

### ⭐⭐⭐⭐⭐ Great product, great value!
*by J***S on August 15, 2025*

Worked great, fit up was good, and after a few hours of use on hardwood I've noticed no degradation so far

### ⭐⭐⭐⭐⭐ This thing WORKS!
*by N***H on August 31, 2020*

I’m using this to shape oak & cedar into benches, tables, chairs and bowls along with the more aggressive shaping Kutzall discs and sanding discs. Also a chainsaw but that’s not really relevant here, is it? Nah.The good: This baby removes wood! Even hard wood like dried cedar it just chews right in and speed out a spray of dust that smells awesome but gets everywhere. I’ve seen no wear or broken teeth after a full day of nearly continuous use, but it’s sufficiently fine that you can’t really see individual teeth anyway. I would say this is equivalent to a 60 grit sanding disc but lasts a very long time.The bad: None really. You do need to be alert to what you’re doing - it will eat wood FAST, and when the disc is spinning it really puts torque on the angle grinder. Use both handles and hold firmly.Definitely recommend if you’re doing more than a small project. For the cost you can buy about 30 sanding discs, though, so if you don’t anticipate using that many over time then reconsider...it isn’t cheap.
