𝐋𝐮𝐨 𝐤𝐞 8 Pcs Rotary Grinding Stone - 1/4'' Hex Shank Assorted Shape Abrasive Stone Mounted Grinding Point Aluminum Oxide Sharpening Bits for Rotary Tool Drill

Great product

sise & shape perfect for sharpening hedge trimmer

They fit the drill but didn’t cut rust spots on iron posts I was hoping for

Fit my drill Chuck and did the job!

These worked extremely well for my little project. I needed to grind a hole in a piece of elk horn for decorative purposes. It took a little pressure to get the job done, but it worked perfectly.

Should work

They work great hot making holes a little bigger

Value for money: Value for money.

RE: LUO KE 8 Pcs Cylinder Shape Rotary Grinding Stone - 1/4'' Hex Shank Abrasive Stone Mounted Grinding Point Aluminum Oxide Grinding Bits for Rotary Tools (Size: 20mm) Posted: 6/28/2024 Use case: grinding brazed welds pros: good price and holds up well Cons: - 1/4 inch shank won't fit a 1/4-inch collet in a die grinder. You'll have to grind the shank to fit. - Stones were not aligned well on the shank which becomes immediately obvious at 2700 RPM on a die grinder.
