I don't think you're going to find those anymore, except maybe as New Old Stock (NOS) from an antique dealer or Unimat aficionado. If you have them, treasure them! If not, get stuff that's easier to find. HF has a set of 1/4" (6.35mm) carbide insert holder tools that can work on the Unimat DB & SL though your center height may not be perfect. IIRC they're spec'ed for 6mm tooling. These:??

Personally, I think? you'd be much better off with High Speed Steel (HSS) tooling, either 1/4" or 6mm, and learn to grind your own. Last I looked you could get 1/4" HSS tool blanks for under $2 each. Way prices are going, it could be more.??has an 8 tool set, pre-ground, for $48, but from $3 & up for several tools. And 6mm:?

Charles Kinzer gave good advice, too. You will need either a small bench grinder, or something to hold a grinding wheel or mounted stone on your Unimat. IF you do that, cover all the way bars and other precision parts with a rag to prevent excessive wear. A cup of cool water to dunk the HSS bits in to cool them as you grind. You should not wear gloves while doing this, the heat on your fingers keeps you from overheating the tools. With HSS that shouldn't really matter, but if you make tooling out of high carbon tool steel, if you let them get too hot it will ruin the edge. High carbon tool steel will take a sharper edge than HSS. If you can grind your own tooling, you can make it any shape you want. Model engineers will grind a profile to for the rim for a scale locomotive wheel, for example, that you'd have to pay some serious money for to buy pre-ground, and you might not be able to find it for any price. That's why learning to grind your own is recommended.?

Good luck, and have fun!
