Review on π Diamond Masonry Drill Bit with JINGLING Glass Drilling Capability by Russell Rabbach
Lake Superior Agate Drill Bit
They are excellent for Lake Superior Agates. I drilled holes from 6 quarters to 1 inch deep using only 2 drill bits. Keep the water flowing and light pressure, they cut great. Between uses I clean the core, then they cut even better.
Pros
- Diamond Coated Hole Saw, suitable for drilling holes in glass, marble, tile or granite
Cons
- I will add later
