Amana Tool 45525 Carbide Tipped 1-1/8 Dia x 1/2 CH x 1/4 Shk x 1-19/32 Long Spoilboard Surfacing & Flattening 3-Flute Router Bit

Made a lazy Susan from a solid piece of walnut for a wedding gift. After my husband built the jig I was shocked at how fast he was able to flatten the piece on both sides. Of course after sanding and finishing it was beautiful! This was much less expensive than other bits we considered.

After getting a router sled at a garage sale, I bought this bit after doing the research. I was pleasantly surprised how quickly it flattened the top of some pretty dense wood. It still has a very sharp edge & I believe this bit will last for a long time to come.

Really good router bit. Amana bits never disappoint.

This tool seems sharp enough to cut the wood but not sharp enough to keep from burning the wood if you slow down too much.

There are many carbide cutters on the market that can flatten a 'spoilboard', but I could find none that accomplished the task at a price anywhere near the price of this Amana cutter. I purchase a CNC router from Rockler but they did not have a 1/4" shaft router bit to flatten the spoilboard. I have used this Amana bit once and it performed perfectly. I expect my spoilboard will need to be resurfaced only 1 or 2 times per year, therefore an expensive cutterhead with multiple 4 sided carbide chips is not required for my needs. If i had a production shop with heavy duty requirements, I might feel differently.

I don't usually take the time to leave reviews (especially on a consumable-ish item), but this bit is amazing! It is very reasonably priced for the quality and eats through wood and epoxy with almost zero tear out/burning/etc. If you are using a standard small straight bit to do your flattening (like I was), do yourself a favor and pick this bad boy up. I usually had to spend a good hour to get router marks out, and it takes about 5 minutes after getting this bit!

I flattened 3 small slabs. The bit worked very well.

My expectations were low due to its affordable price point but was very pleasantly surprised. I’ve used this but to surface 6x 24”x36” end-grain cutting boards so far and it’s still sharp!

It's always a crap-shoot buying tools from amazon. This is a quality tool. Used it to rough-plane several hardwood (ash) boards with a router sled. This bit cut like butter, even when taking off up to 3/8" depth for the full width of the bit.

Amana is a guarantee as usual - durable and it does what it should.

Awesome surfacing tool, saves me tons of time flattening my cutting boards. I run it at 150-200ipm on my shapeoko taking only a .050" doc. Cuts great!

I've surfaced my waist board numerous times over the last 5 years and it's still sharp

Why haven't I bought this sooner, I make chopping boards as a hobby and after reading the reviews I decided to give it a go, definitely money well spent it I used this in my Palm router on a router sled and It did the job in a quarter of the time my other flattening bit took, I can't recommend this product enough.
