Id like to replace the cutters on my Giraud with a standard square insert, but I dont even pretend to know anything about machining inserts. The idea also came from looking at a Henderson trimmer and the fact they just use what looks to be a flat cutter, and you do the chamfer deburr after trimming. I pondered buying a Henderson, but honestly I dont like having to insert my case into a holder everytime, so the Giraud is a little faster there.
I dont hate the Giraud inserts, but I change calibers often enough that setting it up perfectly to cut the correct length and chamfer/deburr is getting annoying. I thought about buying spare cutter heads but at $51 a pop, and Id need 8 of them, that starts to get spendy fast. I also dont mind doing a quick chamfer deburr by hand as I work thru priming.
My thought was to use a 1/8" thick, 1/2"X1/2" insert like this: https://www.grainger.com/product/MICRO-100-Square-Turning-Insert-1-2-18D740
Would this work? Do I need to worry about clearance angles? A chip breaker function might be useful to prevent bird nests? Any better options that someone that knows more about this than me can think of? Any cheap options out there as this is honestly a pretty low stress environment its going to live in so it doesnt need to be fancy?
For now I just want to buy 1, and give it a try. If it works well, Ill probably switch over to doing all my brass with a standard cutter like this.
