      After a face mill but not the fly type.

      My axmisnster, Emco copy, has a M2 taper. Maching mild steel and aluminium.

      What do you think the biggest dia my machine will handle?

      Any views on the ones available from far east ie –**LINK**

          The "real" Emco FB-2 manual shows a 40 mm dia face milling cutter, if that helps. 50 mm probably OK

            The item referred to looked fine, but I would be Very apprehensive about ordering with that amount of negative feedback.

            If you do take the plunge, do let us know the result.

              Agreed re negative feedback. However this link was just as an example. This is better although not many sales http://www.ebay.co.uk/itm/MT2-M10-Shank-400R-50mm-Face-End-Mill-Cutter-10pcs-Carbide-Insert-APMT1604-CNC-/262770375002?hash=item3d2e55b95a:g:F0YAAOSwux5YWM3K  I always look for the best feedback, harder when buying from China tho, and best delivery

                  PayPal should cover you if there are problems, obviously long lead time & will you get charged VAT on the Chinese ones?

                    I have one shown in Tony's link, I have a Warco WM 16 mill with a MT2 spindle & it has coped with what I've given it, nice on ally & brass, but I don't give it stupid doc's, your machine should be capable of handling it.

                        This thread prompted me to look at some of these.

                        Some are used with round (RDMT1003) inserts; some with rectangular (APMT1604) inserts. What would be the pros and cons of the two types?

                        Presumably the rectangular ones gives two cutting areas while the round ones give somewhat more? What else?

                        I could imagine that the round inserts give a better finish at the expense of depth-of-cut but I don't know.

                          Round or triangular cutters will have near zero rake on the cutting face. APMT, APKT inserts have a positive rake molded into the insert and will have reduced cutting forced. I have two insert cutters, 2" diameter with APKT inserts and 3" diameter with SEKT inserts. The SEKT has high positive rake and takes less horsepower and feed pressure than the APKT. Downside of the SEKT insert is the 45 degree lead angle.

                              Round inserts can't cut to a square shoulder without leaving a radius = to the rad of insert..

                                My friend has just recently bought a 160mm self centre chuck direct from China and ended up paying VAT. Almost as expensive as UK with the VAT.

                                I personally have bought items up to about £45 from China ( motorcycles and tooling suff ) but never got an extra VAT request. Never really spent more there.

                                Not sure if they just do random checks or if there are checks when weights rise like for a chuck.

                                  It's even worse buying stuff from the US.

                                    Not sure if they just do random checks or if there are checks when weights rise like for a chuck.

                                    There are a few things to consider.

                                    Always seem to get the £8 collection charge (along with VAT added) if the parcel is bigger than 2kg (small parcel limits) and so delivered by parcelforce.

                                    Anything over about £15, including delivery, can attract VAT (you can look up the actual limit).

                                    Things often get pushed through at busy times, if you are lucky – just before Christmas for delivery can be a good time for getting lucky.

                                    Often just pot luck if you get charged for smallish items at any time, unless someone, somewhere, notes multiple orders to the same addy.

                                        Avoid using DHL for starters. They charge you a tenner if you incur any paperwork – on top of any vat and duty demanded by the IR. Freeloaders.

                                          Good thinking Emgee – I missed that one. And thanks for the other comments folks. I might just get both types and one arbor.

                                            I would get two arbors, once the head is fitted to the arbor, its best left there, infact I would have difficulty separating mine.

                                                  I have a few different types, some old and some new.

                                                  If I am literally just blocking up i much prefer my round ( button ) tipped because of the better finishes it gives. Also has more inserts than my other cutters and is slightly bigger.

                                                  Yes as mentioned you can get them with a decent rake on tips

                                                  Yes they do tend to look as though they are overloading sometimes, but what one or two may not realise just why.

                                                  If you take a face mill with say triangular tips set at rightangles to work surface and you put a 4mm cut on then you have approx 4mm off cutter tip in contact ( ignoring tip rads ).

                                                  If you did this 4mm depth of cut with the button tipped face mill using say 8mm ( for ease of calculation ) dia tips then you have 1/4 of the tips circumference in contact. Works out a tad over 6mm i.e 50% more area than the example above.

                                                  This logic applies to using round button tools in the lathe, as I like using them there as well when i can. I think its liken to what they term as broadcutting on a shaper etc.

                                                    Hmm, looks like I will be eating my words as the face mill has not arrived

                                                    I have now sold the Emco copy and intend of buying a Warco WM18, so what size do you think I should buy for that mill?

                                                    Also, am I correct in thinking its better to get round cutter compared to the triangular ones?
