I don't use this any more, I trimmed about 500pcs with it and that is all. It trims, chamfers, and deburs all in one step. Pretty slick tool for high volume .223/5.56 reloading. I don't currently own either of those though so off it goes. There are some brass shavings in it because I have never removed the chip guard. Giraud tool claims these will trim thousands and thousands of rounds before the cutter gets dull and the cutter doesnt cost much to replace once you own the tool. It chucks into a drill for use. Selling for 85TYD. Probably the best trimmer for high volume until you step up to the 500 dollar Giraud. No trades please, paypal or MO. Thanks
