Always used abrasive wheels in the past. Picked up one of these at Tractor Supply recently.https://www.grainger.com/product/48R...!438760353028! And I am impressed. Made probably 30 cuts on some 1/4" brackets that I am stripping off of an old trailer and it still looks like new. Would have probably been through 5 abrasive wheels in that time. Anyone else using these or similar?
