Amana ToolSpektra Extreme Tool Life Solid Carbide CNC Compression Spiral Router Bit 46176-K-5, 1/8 D x 13/16 CH x 1/4 Shank x 2-1/2 Inch Long 5-Pack

I use this bit in plywood, and being a compression bit and using proper feeds, speeds, and initial cut path you get a really clean and reliable cut. This bit lasts a long time too, other bits do not last as long as this one does. After several uses, it still cuts like new, no degrading as yet and I have used it long enough to have ended the life of other bits.

I've never been disappointed with an Amana tool. They are well made and long lasting if you take care of them. Leaves a nice edge.

Made the same mistake as others buying this but thinking the price and it being manufactured in the states would mean high quality. Was running it on my 1F as a replacement and kept the same feeds and speeds as a 1/8” Jenny(The Slim Jen). This bit was screaming and I had to reduce the feed rate 20%. Made 10 cuts and this junk snapped just like another reviewers. Save yourself the hassle and money and buy some Jenny bits for half the price.

great bit

Product shipped quickly and does exactly as advertised. Very pleased

Absolute waste of money. Absolute garbage. Look elsewhere, as this bit is the most overpriced piece of metal you'll ever spend money on. First one I bought snapped, so I thought maybe I pushed it too hard, made adjustment. I said, okay I'll be super conservative and will take it easy, second one also snapped after limited use. So I said forget it, and bought FIVE Chinese bits for a third of the price and they worked great. I decided, what the hell let's give the ol' American Amana a third chance, using the same exact speed and settings as the same spec Chinese bit. Guess what? Yep, it snapped. So now they owe me +/-$190 not including time wasted. Go buy the Chinese bits, and you'll thank me for it. FIVE for less than $30. DONE WITH AMANA.

After a couple of runs cutting soft 1/2” ply, it just snapped, and I’m left with a half-done project. Super disappointed.

Snapped of 2 minutes into a cut of 1/8 " mdf
