We use these in my shop to machine aluminum pump bodies on a mill. I have a 9 tool rotary cutter and I can get roughly 100 4” diameter bore cuts out of one cutting edge. 400 per insert is well worth the money and they provide a beautiful finish. They are definitely cheap enough to try, and if you take care of your tools you’ll probably love ‘em.

I use these for parting metal on a lathe. I have not had any problems parting up to 1 3/8” round stock. I can’t quite get 1 1/2” because my holder bottoms out just before it gets that deep. I’m completely satisfied with these inserts.

I have tried MANY different APMT1604 inserts and they're almost immediate destroyed when CNC milling 304 stainless. These are the first ones I've found that have reasonably decent tool life. They probably won't last as long as a brand name like Sandvik, but they are quite good. I think the price/performance ratio is excellent.

Used these inserts on my mystery stainless header and they came out un phased. Would buy again if needed

Held up well in my Manual Vertical mill, 2" shell mill. I cut some case hardened brake press tooling and they held up pretty well for being an Iscar/Ingersoll Knockoff!

Great tool, leaves a beautiful surface finish on aluminum up to 5.95" wide with Apkt160408-Lh Carbide Inserts, available on Amazon. the inserts that are provided are not great for aluminum. Slow head speed and feed rate are the key to a nice finish

Been machining soft steel and some tool steels. Inserts are holding up great. Worth the purchase.

I used this product for machining low carbon steel and the cutter performed nicely.

These inserts are good. They hog out mild steel with deep 0.200 cuts and leave a good surface finish on the final pass of 10 thou'.Tough too. I see no sign of wear after making a good pile of chips.The chips it makes are nice brown or blue and the chip breaker works well.
