Purchasing milling cutters
Looking for recommendations, where to buy Tungsten end mills (and other milling cutters) in Australia ?
Tungsten is so damned expensive. I'm particularly interested in cutters larger than 12mm, like 16 and 20mm 4 flute.

Id just contact a rep for a manufacturer like guhring, sutton, iscar etc and either ask them directly or get them to reccomend a supplier. When I buy new I usually try for new old stock off ebay first and failing that just buy from a rep.

I avoid using large solid carbide cutters bigger than 12mm because of the expense.... I do use carbide insert endmills in larger sizes. I find that more economical given my propensity to chip things....
I find the quality of M&G very acceptable:

Toolprocure sell DHF solid carbide endmills, which are quite well priced and work very well. But you would be looking at over $200 for a 20mm.
At work we use indexible endmills for anyting over 12mm, works out much cheaper.

I recently bought a 14mm insert endmill from Banggood just to give it a try.
I haven’t been a fan of the cheap generic BAP400 style face mills ex eBay etc but love my Kennametal 63mm facemill.
I was pleasantly surprised with how the Banggood insert tool performed and their “blue nano” inserts.
As others have said - inserts are much cheaper to run than solid carbide for larger tools and will be the direction I head going forward for larger end mills.
For smaller carbide end mills I’ve found the Magpro (M&G) ones good for my use - but I haven’t had any proper branded ones to compare with so YMMV.

Lots of votes for indexable end mills I see.
I haven't tried them but would have thought indexable as a harsh interrupted cut compared to spiral cutters which tend to peel away the metal.
Anyway, my round column mill might be a bit shaky to use them.

I have a 20mm and a 16mm insert end mill that I use where ever possible. They have their limitations but they are cheap to run, they use the APKT etc inserts.

The nicer ones use an APKT style insert, which has positive rake in all directions and cuts very well.
Solid carbide is still unbeatable for finishing cuts where you need to use the full length of the tool, but for general material removal and facing cuts, these indexables are the way to go.

Another vote for indexable end mills, and you can even buy HSS inserts. AJ Warner in the USA makes HSS inserts at reasonable prices.
https://www.arwarnerco.com/
https://littlemachineshop.com/info/inserts.php

I'm always surprised nobody seems to be aware of these. Great for brass or when you want either a super-sharp insert or a big nose radius, or even want to grind a profile for some weird job. Also, their HSS blanks are excellent quality. Harder to get shipped from Amazon, just use a shipping service.
