Much better than standard steel tool - RCBS Trim Mate Debur Tools - Carbide

This is actually a chamfer tool rather than a deburring tool. I replaced the standard one on my Franford Arsenal Case Trim & Prep Center with this carbide one and the difference is amazing. Whereas before I had to tightly grip the case to keep it from turning in my hand,Mathis carbide tool is so sharp and slick that it chamfers the case like butter. The only negative is a high pitched squeal but it isn't a big deal and I didn't downgrade my review because of it.
