Just put a new Carbide cutter in my used WFT 308 trimmer. Yeah I bought it used & cut about 1K brass on it myself. No change from start to finish in the feel with the original cutter. Original cutter is HSS. New Carbide cutter off ebay was $13 shipped & WOW what a difference. Minimal deburring needed. Honestly I would only hit the inside on the last 100 I trimmed witht he new cutter.
