This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.
Of course. I would venture to say that literally millions of lacquer records have been cut on these machines over the past 50 years or so. They were really meant to cut records, not emboss them, although embossing was certainly a viable option.
There is a wide variety of cutting styli appropriate for these machines, from steel to stellite, to sapphire, ruby and yes, even diamond (note your link was for a "synthetic diamond").
You will find the sound quality of a cut record far superior to an embossed record.
This assumes you're cutting an appropriate disc, generally a lacquer or "acetate" coated disc, although there are other options as well.
I'm sure on Youtube you could find hundreds of cut Presto records being played.
Most commonly used cutters are, I'd say, sapphire or ruby.
With this machine I will cut mainly lexan and myshank blanks. Will try laquer some day just for the feeling but I'm not that deep If I'm correct lexan and myshanks are cut with diamond. I know I put link to synth, I only chosen it because of the 50% more life as stated in the description, don't know any other differences now.
I've been searching a lot before decided to post here. Unfortunately on youtube I did not found anything much helpful on the sound quality, everyone seems to be embossing or audio is recorded from the camera's mic. I will appreciate a lot if someone provide sound clip of mono CUT record. Already heard some embossed examples from guys here which are ok to me, but I want to get the max out of this machine even if its just for one time. This makes me think that maybe a stereo cutting head will also work? I hope so! Of course, maybe with modification but this is another story and not for now...
With Myshank diamond styli you will be cutting, NOT embossing. You will get better fidelity, but you will also have more difficulties with things like chip and stylus life. That machine is not very well set up for cutting diamond because you need vacuum, stylus heat, etc.
However, Kyle at Soniphone records uses one similar (the only person I know that uses diamond cutting styli on a swingarm lathe), so you might want to email him for some tips.

Thank you for your help guys! Already got reply from Soniphone records. Even recorded with camera their records sounds really good, so first thing to do when I get my head from Tod is to get a diamond and try myself.
