Cutting oils

[flatlineParticipant @flatline]

I am reading Geo H. Thomas’ book ‘The Model Engineers Workshop Manual’ – published in1992 I think….

on the subject of machining silver-steel he ‘thoroughly recommends Shell Garia H’ as a cutting oil…

Various internet searches have provided no further info, so no doubt this ‘Garia H’ has been replaced by a newer product, but can anyone tell me by what, or an equivalent??

Many Thanks in Advance 😎🇬🇧👍

Couple of mins found its replaced by Garia TC12.

Its nothing more than a neat cutting oil for industrial heavy duty applications as:-

• deep hole drilling
• broaching and tapping
• gear cutting and shaving
• reaming
• grinding, honing and lapping
• turning, planing, shaping, drilling and milling

Outside realms of hobbiests theres many others, worlds your oyster on better serving lubes.

Many thanks – a ‘Google-Search’ provides zero information tho… 🤷‍♂️

That was Google!

Ok… so I ‘Googled’ Shell Garia TC12… but I certainly can’t find any reference to a current source.. 🤷‍♂️

I cook my own from rape seed oil. Just add 5% sulfur and heat gently until all is dissolved and the oil darkens. Smells a bit funky and will harden over time if exposed to air, but works just as well as Rocol RTD (if not better).

Same question into Google AI seems to give a more up-to-date answer. Shell no longer manufacture the Garia brand.

I use Clarkes cutting oil. 1 litre bottles. Last ages so the cost is minimal.

I will try that, if I ever run out of cutting oil.  Seems to be really cheap, apart from being very effective.  Is 5% the optimal, maximum that will dissolve or just asequate?

Unles syou want to by 20lts plus I would suggest looking at what is available in hobby size quantities rather than looking for the closest match to an industrial product which won’t come in 1lts bottles. Also the technology put into cutting oils has come a long way since then and ther will be better products for the job.

I just had a look at the very comprehensive reply, most interesting.

Shell Garia H was replaced many years ago. The option to purchase Shell metal working oils in 5 litre cans also went about the same time. Like Castrol they only want to deal with bulk users.

I have found a product by Smith & Allan to be extremely good and will work well with brass. It certainly stops the small splinters of brass from flying everywhere.

“Neat Cutting Oil for Sawing Threading Milling Turning Tapping Drilling 5 Litre” If you put this in a Google search along with Smith & Allan it will take you to a source. I can lasts me several years. I have found the small plastic dispenser bottles with a detachable needle point to be an ideal applicator.

Gray,
