Inserts

[DalboyParticipant @dalboy]

When I placed my order for my new lathe and milling machine I also ordered a set of carbide tools(I know not best to order sets but I got a good deal on them)

Anyway can anyone point me in the direction of any charts that explain what inserts are for in relation to type of turning and materials they are for.

I noticed that there are so many different numbers and categories when I look at websites that sell them.

Sorry for so many questions but we all need to start somewhere and when I last done any turning and produced something was at school(Many moons ago) and that was HSS tooling

I find the chart in MSCs catalogue easy to follow, page 390-391

Warco do have some quite obscure inserts in some of their sets which have been discussed before.

A most excellent chart but one that definitely wants printing out, preferably on A3 paper, to follow easily.

Objectively way better than the one I use.

Really needs a bit of back up from a comprehensible reference to ISO material classifications and one of the nice diagrams showing what each shape is used for.

That said I think its likely to be TMI (Too Much Information) for a neophyte who doesn't really know where to start. Heck it would be quite capable of confusing me if I just dived in trying to figure something a bit obscure and I've been using inserts for 20 years or more.

I've long felt we need a "Just Enough About Inserts" article or reference written for the Model Engineer / Home Workshop Person to take the inexperienced and neophytes through the basic "practice" maze. Having got the basics explained in organised fashion its then its up to them if the want to delve deeper into the real thing.

Plenty of good advice out on the internet but, unfortunately, it all sort of just growed and much is now somewhat outdated, whether by fact or application, in terms of what to buy now. My stock works just fine but its all technically obsolete!

Lots of contradictions around the edges too where folk are talking about different applications. Doesn't help when a goodly part of the advice tends to boil down to "Do what I do and you will be fine." But whats a neophyte to do when Jack says do this, Joe says do that and the YouTubes show two different approaches working fine!

Writing a coherent "Just Enough About Inserts" will be seriously difficult given the variety of machines we use and the need to have a coherent, progressive, structure but surely there is someone out there clever enough to manage it.

I know you should get to used to what tool does what job but you have to be flexible with what tool you use. I use occasionally a part off tool for facing a shoulder or step especialy on right hand side and have eavan used a boring bar to turn the outside diamiter on a long job in reverse and at the back of the lathe. So look at the shape of the job and what tools you have and have a go preferably on test pieces or scrap parts. If not sure ask that's my moto and have a go.

Clive If you ask them nicely or place an order they will send you that catalogue in paper form so you can tear out the two A4 pages and stick on the wall, what you do with the rest of the 60mm thick catalogue is upto you.

[DalboyParticipant @dalboy]

Thank you Jason a good chart for me to look at.

David I agree about getting use to the tools I have used some tools when turning wood for other uses than what they are designed for with knowledge of what would be dangerous and what is not. Many techniques I use I would not advise a novice to try like trying to turn a piece of wood that ends up like this.

Much depends on what set you’ve bought. Some of these sets are aimed at hobbyists and seem to use non standard inserts so any commercial specifications may have little bearing. You may also be restricted to buying replacement inserts from the original vendor in whatever grade they deem suitable.

This catalogue gives a clear guide to what each different insert is used for. It also includes data on insert sizes and grades for cutting different materials etc.
