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

There are a lot of bad reviews complaining about this bit breaking. Where the bearing is the diameter is only about 1/8 because the bearing needs to fit flush with the cutting edge. Of course it will break if you push hard against a hardwood like other reviewers said they were. Using the right tool for the right job this is amazing. I am using it for installing futures fin boxes into surfboard blanks. Needed a pattern router bit to cut polyurethane foam that is under 1/2 diameter. This bit works amazing for it. I would never expect this small of a bit to cut African iron wood, but if you have a basic understanding if stress in materials, then this bit will exceed expectations.

Used this to make dutchmans to fill in for where door hinges were. Good product for the money

These are great for the first couple of minutes. The bearings will fall apart in literally two or three minutes, and if you’re lucky, you won’t ruin your project. Start with a larger bit and bearing , and clean up your work with this bit. That way you can get at least part of it done before the bearings go bad.

The project Im working on requires that the bearing and the cutter be the exact same size..... The cutter is .005 smaller than the bearing causing too tight of a fit of the finger joints Im trying to fabricate.... Other than that the quality was very good....

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

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.

Decided I wanted to have smaller radius edges on a set of stairs I was building vs the somewhat boring bullnose treads you usually see. This bit held up for 4 stair stringers to cut the small radius to fit the treads into. Did a great job and the results were worth the extra work!

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.

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 :-/

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
