Amana ToolRCK-457-DLC Solid Carbide Insert Cutter Replacement Knife Blade for Solid Wood, 4 Cutting Edges Diamond-Like Carbon (DLC) 12 x 12 x 1.5mm x 45 Degree Angle

I would give 5 stars for product performance, but the price is too jacked up.I bought the Amana RC2255 3-wing spoil board bit for flattening slabs. It works very well and makes a nice cut. I recently replaced the 3 cutters and was shocked to find out the price of 30.00 is for only 1 cutter. It cost me 90.00 to replace all 3. I cant afford that, and I know many wood workers like me cannot either. So I found another brand 4-wing cutter with square (4 sided) carbide cutters and the replacement cost for this new on is only 3.00 per cutter, 30.00 for a pack of 10. And it works just as well in mind opinion. Now I can change all 3 cutters for 9.00 instead of 90.00.Amana... You've lost me as a customer, get a grip on your pricing.

For the price I was expecting a full set of 4 blades. To my shock it was $32 for each individual blade... How is that possible??

I ordered a bit and knives. The packaging that Amana uses allows the knives to fall out. When it arrived I had an empty package. After advising Amazon, they sent a second package, which contained a singular knife and missing three!

The media could not be loaded.  After using the tool for a few simple projects. I went to turn the blades for them to fall apart on me and making me cancel 3 orders.

It is a great system but 30 each for replacement cutters I can buy another brand and replacement cutters for what replacement cutters cost. So I guess when I have used up my last face on the original cutters. Throw the bit away and buy a new more economical system.
