Parting Tools

[Nathan SharpeParticipant @nathansharpe19746]

Good evening ,

Your collective opinions and advice are requested on choice and range of parting tools and parting systems. I have various inserted tip tools and parting blade tools already in use. Up to about 2" I favour the Eclipse type of tool (machined bevel not hollow ground) and above that Iscar and Sandvic using a centre grooved insert. Given the current state of the UK,s finances and my own, I'm wondering if I should cut back on the inserted tip tooling and stick to Eclipse. Tips are expensive even from Ebay, Eclipse are at least nominally British. What diameter would you part off with using an Eclipse tool and where would you decide an inserted tip tool is required? My lathe is a Harrison L5 in good condition and has been used so far with a maximum LxD of 4.5" x 12" in PB and cast iron, but only turned to finished diameter and then cut to length before re machining. If you favour Eclipse type tooling what blade size would you suggest for 2" to 4" work? The workshop is mainly used for hobby work with the very occasional "earner".

Thanks , Nathan

Hello again,

Do any of you know wether the parting tool blades sold by RDG/Chronos/Arceurotrade etc are bevel ground or parallel ground?

I,ve only ever used genuine Eclipse blades but may have to consider imports as far as my finances (SWMBO) are concerned>

Nathan.

Hi John,

Thanks for the reply. As I,m sure you do I believe that no system fits all jobs and it was never my intention to stop using inserted tip tooling,only to try and reduce costs. My thoughts were that as diameter of work increases then depth of parting blade should also increase. I can use a 5/8" blade for 2" work so how far can I go with a 3/4" blade ? The Mircona system is what I,ve been looking at, as you say it is costly but could save money in the long term. BTW how's the four legged white sausage?
