trapper:
Its impossible to know if these are any good, but they are coated so should be ok,price is ok,but l would be inclined to ask him that you want to purchase a single cutter,to try and if they perform to a decent standard you will purchase a set-hasn,t had many sales
Jonny:
I always shy away from the cheap Chinese cutters, what you think may be cheap will be false economy.
Quality ripping cutters are very expensive certainly the last 6 years 10mm dia looking £30ea. Both above links are just HSS and wont last or cut very well due to flex, in fact due to ripper it will wear quicker and a waste of £58. The Arc are a little better for softish materials. The difference milling out QR tool posts above links will wear by time first pass made opening the slot up, quality will open up 3-4 tool posts although around 5 times dearer.
If buying any look out for cobalt types such as this http://www.ebay.co.uk/itm/ONE-CLARKSON-PREMIUM-HSCO-12MM-RIPPA-CUTTER-TICN-/181805849516?pt=LH_DefaultDomain_3&hash=item2a54791bac
New wouldn't be far off the cost of the whole cheap sets together, have a fair few and hate buying them
trapper:
Yes l agree about the chinese import comment,the cobalt ones are the one,s you want,still say you will get one reasonable off ebay,l would even go for a high content cobalt one that was second hand,as if used correctly the cutting edges last a long time,just buy single at first dont go in for sets unless you are offered a set of quality ones at a good price,if your looking for anything in particular related to milling or turning let me know might be able to help you
John Rudd:
Guys,
Thanks off the advice, but as it happened I called into Arc en route to Northampton.
I needed a qctp for my big lathe, so while
I was there I got a full set at a discounted price..... :clap: well I got all of them as a set with the 6mm free....good readily I'd say...
