I am looking at buying a 8 mm shank parting off tool that uses a GTN 2 insert. This is from a UK supplier.
I am a hobby user and will probably part off no more than 20 items a year. Working mostly with brass ali and delrin with the odd item in cast iron, leaded steel or 303 stainless.
So I am thinking that a couple of spares will be enough. I can buy from the UK supplier of my parting toll and they charge $ 4.30 for one.
Being a tight Scots git I checked the online price. I could get 10 for $ 6.99 on Ebay or 1 for $17 US supplier. Curiously the label on the cheapies gave the same US manufacturer as the $17 one.
I checked Banggod but they don't seem to do them.
So my questions
Will 2 spares be enough. Bear in mind I live on a sailboat wandering around the Eastern Caribbean and my delivery logistics can be convoluted
Is there a benefit on having a tin coating.
and the sixty four dollar question is the $17 insert 25 times better than the 70 cent one. Or do they all come from the same factory and get different packing and prices like small outboard engines.
