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.

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

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.

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 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.

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....

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.

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.

I was very excited to use this new bit. I started out by using another bit to remove all but maybe 1/4” deep then I was going to use my new bit to make the final pass. Plunged the bit in, made my cut and when I pulled up the router I saw the piece of blade among the sawdust in the new cut. It was maybe a 1/4” of wood, cut inside a small bow tie template and broke the first time, probably within 30 seconds. I’m disappointed because I have many templates that a need this small template bit for. Really hoping to find something i can use.

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!
