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

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 :-/

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

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.

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

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

Cut fast, no kickback, easy to use.

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.

Came quickly, clean cut

Should preface that mesquite is the wood being used to review this bit, but it only lasted for about an hour of cumulative use before the bearing was no longer reliable. Will still serve just fine in the router table taking tiny bites on pieces that can use the fence as a guide, but wont be using this one for template work anymore.
