The title says it all. I'm looking for an upcut spiral router bit 1/4 or 5/16, that is longer than 1 inch in the actual cutting area. Need to make some mortises about 1 1/2 deep and would like to try this approach as my right arm is about falling off from using bench top mortiser. Any help in locating would be appreciated as I can't seem to find anything longer than 1 inch.
Thanks!
