Kennametal inserts for trade

[Naiveambition]

I have some indexable inserts for trade. I'm looking for corner rounding end mills.

There are two different brands
Kennametal
1 5 pack of dnmg432mp These are the diamond shaped ones

1 5 pack of ng3125lk. These are for cutoff or I think internal grooving

Tool flo

1 8 pack of s1252154n4. Threading inserts I believe

1 9 pack of 5203300at50. Threading inserts.

Like I stated I am looking for corner rounding end mills from 1/8 to 7/16. Up to a 1/2. Any questions feel free to ask

Have you considered using woodcutting router bits ?

They work just fine and are cheap. Get the thicker shank ones if you can. The 1/4" (6mm) shank ones tend to bend if you get a bit heavy handed with the feed rate.

Yes I actually went and bought a router bit set at harbor freight. Of course they turn out to be the 1/4 inch shank. But their is also the problem of the bearing.

The cut I need to make doesn't give room for much more than the cut, so the bearing kills the prospect. I've heard of others using router bits so I thought I would try it. Also not knowing the exact radius I need complicates it even more.

I wouldn't be scared using router bits in aluminum or brass, but since I'm working with steel on my current project im hesitant. For a end mill they are quite pricey. I can only find individual sizes at enco for roughly 25$ a piece, with the sets running around 125 and up. If I don't get hits on these trades I may try making one myself. It's only a small 1/4 inch long cut with 8 total cuts. So doesn't need to last long.

I had read somewhere on one of the builds where he made one but I can't find the thread again.

I'm still unsure if they'd be any good for steel, but I bought a set just for the rounding over bit and cut the bearing arbor off as it was in the way. Still worked just fine as the bearing is only really a guide for manually running the router down the stock. It's not required when using a mill.

Just take the bearing off then cut off the stub. Using then on steel or cast iron is not a problem. Just run them at a speed that feels comfortable. Since the cutting edges are carbide they can be run quite a bit faster than HSS. The only real problem is the small shank. I tend to buy the 0.5" ones when I can get them. I paid £12.99.00p UK pounds for the last set of six cutters I bought. Just over £2 each. Come to think of it that set didn't have any bearings on them.
