As per title, is there such a thing, google brings up some half rounds, could do with one about 25mm diameter.

Anyone know a source?

Cheers.

Dreadnoughts are so course - I can't imagine making a round one. It would look like a long thin fir cone

Would a Stanley Surform do the job?

Would a half round Rasp be any good for the job in hand.

Thanks Chaps, I need it to open out and shape the ports in an intermediate plate for a manifold I'm making.

I'll continue with the rotary burrs in the die grinder if theres no such thing.
