Yes!!!! Forster 3in 1 trimmer will trim, chamfer and deburr all at the same time. Works great! Makes a very tedious job a snap to complete.OK. My Internet skills aren't the best so...Is there anything available that will let you deburr and chamfer at the same time?
Whatever you use should not remove too much material. You don't want to form an effective leather hole punch. The end should retain a square cut surface considerably wider than 50% of the neck wall thickness, for durability.
