Amana Tool - 45475-S Carbide Tipped Flush Trim Plunge Template 3/8 Dia x 1/4 Sh

This is my first Amana router bit, and wont be the last. Great carbide. Very sharp. I used in a pattern cut I was making for my grandson. Very clean. One of the shortest overall length router bits I have used too. Used it in a Bosch Colt router.

Durable, engineered and manufactured according to high standards. I use these great bits for mortising out hinges, strike plates, mostly, but they provide so many possibilities, with great accuracy, for a very reasonable price.

This is a fantastic router bit when used properly. It seems fairly fragile so Id never try to cut more than a few mm of depth at a time or cut too quickly with it. But taking shallow cuts and working slowly up to the pattern, Im able to make recesses for illuminated guitar truss rod covers. It cuts so cleanly and thoroughly that it left a shiny surface on the wood I used it with. Had no problem cutting through maple, mahogany and cherry.

Came quickly, clean cut

Hard to find size . Good quality. A little expensive, but not many other choices.

I bought 2 of these bits wich was tough to swallow at that price point but i needed to clean out some corners on a hardwood project and wanted an easier way than chisel... bit dulled almost instantly, bit snapped at the bearing before i could clean the first corner. Grabbed the second one and it lasted till 3rd corner and also snapped.... my other amana bits are great but these have a weak link

Ignore the folks that are breaking these bits. They’re forcing the bit at slow RPM and feeding toooo faaaaasssst. Run at very high rpm and move very slow to make sure you don’t chunk out and it cuts perfectly - very nice!!! This bit is for detail routing, it’s not for removing big chunks of wood. I’m using these to do you final passes on pickup routes for tight radiuses and it works perfectly!!! Make sure you take care of the bits by cleaning them up before putting them away and they’ll last a long time.

I bought this bit to route multiple cavities in electric guitar bodies. I should have checked the overall length of this bit before I ordered, I assumed that it would be at least the same length of its smaller sibling, the one that it is just 1/4 diameter but this one is shorter. For the router table, if you have a thin insert you should be alright, I have a 3/4 inch MDF table and this will not clear that that distance with a 1/4 inch template at all, at least not if you follow the minimum insert distance that is marked on the bit. Using it with a plunge router is also a problem, even when removing the template youre always at the maximum reach of the bit. I just thought since the 1/4 inch diameter bit is considered a delicate toy bit, this one being bigger would be at least of the same length but its not :-/

So I initially not happy because the cutting edge didn’t go all the way to the bearing… so if you have a thin template you can only cut about a 1/16” before stopping to trim the “lip” formed between the bearing and the cutting edge. Annoying, but not a deal breaker. Until the thing just snapped in half! I was routing an existing cavity slightly larger and wasn’t using much pressure. Maybe I just got a defective one, but I doubt it. The broken shaft was hollow!

I love this template bit, and the other tools from this company that I have received. These are very sharp and clean cutting!
