K1215-12mm Square Corners Carbide Inserts 4 Edges (12mm lengthX12mm widthX1.5mm thick-35 Degree Cutting Angle), Pack of 10, Straight-Hole

Cutters are sharp and once replaced no having to reset bits for accuracy

worked great as expected

I bought these blade to flatten several semi-hardwood slabs 3 meters long by about 500 mm wide. I took them down from 55mm thick to 34 mm thick. Very happy with the finished result, they cut exceptionally well, and after all that cutting are still sharp. Very good.

I bought these for a surfacing bit, and the original carbide blades are so long lasting (I am pretty conservative on speeds and feeds) that I have not had to replace a carbide blade yet, though I am on my 3 rotation on the existing blades. Maybe I will have to replace a blade this year.

I used them on my cutter bit cuts nice

My item came in quick. They are working great so far. I like the fact that I can get them in bulk instead of one at a time.

This is identical to the Amana 60° router bit. Amana charges over $90 and the replacement inserts are $30 each. You can buy this and 5 replacement inserts for $55. It’s kind of a no-brainer.

like very much
