ARMOUR TOOLING – 6mm Tungsten Carbide End mill - 4 Flute Sharp Corner Cutter - CNC Milling Tool - for Alloy Steels/Hardened Steels - High Performance Milling Cutter - Roughing And Finishing

I bought this end mill for counterboring pockets in 6Al4V titanium, which means it had to be *sharp*! It not only cut through the ti smoothly amd concentrically, it left a perfect surface finish with zero chatter.I bought the Armour end mill off the back of buying their countersink set, which are also very impressive and cs both ti and annealed steel beautifully.

Surprisingly good for the money, I have been using these with my mini mill for cutting precision slots in various metals. They have been surprisingly durable.

Used this cutter horizontally in my lathe as I don't have a mill, held via a collet chuck. I wasn't expecting it to go smoothly but wow, this cutter is amazingly sharp, and stayed sharp. The workpiece is cast iron with an aluminium alloy extension and the cutter was like a hot knife through butter. After the job, examining the cutter there was zero wear, zero marks, I could hardly tell it'd been used.

I bought this tool based on positive feedbacks and I'm glad I did it. I used it to cut mild steel on a small Proxxon FF230 milling machine, so not a powerful or rigid one by any means, feeding by hand (no feed data, sorry) at 2200 rpm, depth of cut of 0,5 mm + 0,5 mm depth and 3 mm side cut and it worked perfectly. So far I'm happy. I want to test it on a harder material to see what can I cut on my small milling machine, but I suppose its limited speed is a bit slow for this tool. I would like to have other shaped tools like this (round nose, roughing, dovetail cutters, etc.) to choose from the catalog, that's why I only gave 4 stars. But the tool deliver.

Very good end mill, price is good, worked well, good amount of sizes

As you can see in the photo,I cut 8 slots in 1/2 steel blocks 1/4 of an inch depth a total of 16 times using only one of the 3mm carbide cutters from armour tooling,and I really gave this cutter a work out and to my surprise it’s still sharp.I was so impressed I purchased a 6 8 10 and 12 mm cutters I just wish armour tooling offered larger cutters as I would have no hesitation in purchasing them .in the past I have bought more expensive milling cutters and after a few cuts they ended up in the bin . Just wish I could have found these carbide cutters sooner .so keep up the good work Armour tooling .

Excellent end mill for mild and stainless steel. Cuts well and leaves a great finish in the material.Would highly recommend, will be using these mills from now on.

The media could not be loaded. Even in my handmade mill and fed by hand it is cutting like a dream! Used it for a while now, mostly on aluminium, but also on brass and mild steel, and it performs excellent. Rigid and sharp, it's now my favourite end mill for any odd job!
