Another option if you can't shape a cutter.? ?Go to a chain saw shop or dealer and purchase a chain file, they come in various diameters, 3/32 or 1/4" would be good, put them on the tool holder or hand hold them you should be able to get a good finish fast.? ?Their teeth are on a diamond pattern as they are used to cut at an angle for sharpening chains.? ?Just my option.? ?Harbor Freight also has diamond burrs? for dremel tools with 1/8'' shanks that might work also.?
