Hey Mike, The sample plates look great.
Thanks for posting them! The airgraver website was
recently updated (link) with this large bore tool. NitroG20 was decided on for the name from the suggestions in the earlier thread, thanks everyone for that. The G20 portion of the name comes from the weight of the piston, which is 20 grams.
I changed the front end on the tool from earlier prototypes so it can now be made to hold larger graver shanks. The standard tool holder will hold 3/32" square and 1/8" round graver shanks as well as other shanks that will fit within a .133" hole. If someone would like the tool to hold 1/8" square and 3/16" round shanks just let me know and that can be done.

Here are piston weights to help compare the Classic stainless and tungsten pistons to the NitroG20 tungsten piston.
Classic and Artisan stainless piston: 3 grams
Classic and Artisan tungsten piston: 7 grams
NitroG20 tungsten piston: 20 grams
