Carbide 3D sells 2 different 1/32" bits …#121 is a Ball Cutter and #122 is a Flat Cutter. In looking at the photos it sure looks like to me that the pictures are reversed. Does the #122 Flat Cutter really have a ball at the end of it? I have the 1/32" SpeTool downcut Flat Cutter on order and the profile sure looks different from the #122. Has anyone used the #122 Flat Cutters and have an opinion on them? For using with Oramask I would think that downcut bits are the way to go. Is that correct?
I am looking to get the Amana AMS-195-K ‘O’ bits for plexiglass work. Any feedback from the community on these? Are there others that come better recommended from the community?
Does anyone here have any recommendations on a 15 degree V-bit?
The pictures are not reversed. They are good bits but note that you will need a 1/8 in collet (sold under accessories). When using Oramask, a downcut bit is always recommended regardless of bit size. I always buy multiples of these tiny bits because they do break but I have used them successfully in brass on a Shapeoko 3. Just don’t be aggressive.
Amana is too expensive for me. The single flute bits from Carbide 3d work fine.
To experiment I have bought 10 packs of cheap 15, 20, and 30 degree v bits. They break and I throw them away.
I have been using #122 1/32" for 6 years with no breaking in hardwoods and soft. That little bit is a trooper. Being such a small bit maybe yours ground wrong or maybe it hit something hard.
Guy … I don’t have that bit, so I never broke it. It just looks SOOOO weak at 1/32". I do have a downcut 1/32" on order … and will probably get the C3D ones in the near future.
