If Arc Euro can no longer sup[ply, JB Cutting Tools have taken a lot of the cutting tools from Syston

A lot will depend on the power and rigidity of the machine you are running them in.

If a benchtop hobby machine then best run fast and take shallower 1mm – 0.5mm cuts. Though they can also side cut.

As a side issue the pity of Arc closing is the website has lots of other snippets of info like dimensions and screwcutting charts that can be useful from time to time. Unlike books we have to remember the web is ephemeral.
I was lucky to get a certain item a few weeks ago that I didn’t see anywhere else on the web for amateurs – Arc will be missed.

If not using a hobby mill then one can let rip. This is a 63mm diameter face mill and APMT inserts, from Arc, machining hot rolled steel:

Parameters were 420rpm, depth of cut 2.5mm (one turn of the handle), width of cut 48mm and feedrate of 430mm/min. The face mill has five inserts so that equate to a chip load of 0.2mm/tooth and a cutting speed of 83m/min. Removal rate is about 3.1 cubic inches per minute, comfortably below the capability of the mill. The mill is 1970s and designed for HSS cutters. Consequently it runs out of feedrate when using carbide insert face mills. I have been impressed by how well the inserts from Arc have performed.

I detailed the different approach to Julie Ann’s that seems to work well on the hobby size machines here and here

I think this is it:
