I have a gunsmithing project I'm working on and one of the thing I need to do is cut a small groove (0.095 wide X 0.086 depth) into the work piece. The tool bits I have are the pre-ground 1/4" in. set from littlemachineshop.com that includes the LH & RH cutting bits, parting bit, round nose cutting bit, 45 degree chamfer cutting bit, and boring bit. Also using the lantern tool post and toolholders for same. My question is can I use any of these tool bits to cut the grove to the measurements I listed or will I need to special grind a tool bit for it ?? Complete newb and this is the first project I'm attempting on my new-to-me Atlas 10100 Mk.2 so I know "Zilch" when it comes to tricks & tips to make the cut I need. Here is a pic of what the finished product should look like...Notice the groove about middle of the piece. That's the one I need to cut. Thanks.
