Carbide Tipped Flush Trim Plunge Template Router Bit, 45487, 1/2 Dia x 1/2 x 1/4 Inch Shank with Upper Ball Bearing

The Amana Tool 45475-S is hands down one of the best flush trim router bits I’ve used! The carbide-tipped blade is incredibly sharp, providing smooth, precise cuts with no tear-out. It runs effortlessly through hardwood, plywood, and even MDF, leaving a clean edge every time. The build quality is excellent, and the bit stays sharp even after multiple uses. The bearing spins smoothly, making it easy to guide along templates. Definitely a must-have for any woodworker looking for a reliable, high-quality router bit. I highly recommend

Yes this is a tiny bit, yes you have to go a little slower, but the bit works. I used this on a clock face that I was making out of teak. The template had cut outs for the numbers that required a very, very small bit. I slowed down the router and the bit cut through the teak like butter leaving a smooth cut out. If you have a template with narrow cut outs I’d recommend this bit, just go slow and the bit will be fine.

Should have got one of these before! I used it (so far) to make an accent/inlay line around a circle. Previously used a straight bit and that one left lines when I plunged into the work piece that I'd have to attempt to sand out. This one is amazing; pretty sharp, cut very smoothly, and left a super clean line with no sanding needed when plunging. I don't think you can go wrong with this bit.

I really wanted to love the Amana Tool 47222-S. On paper, it’s exactly the bit I needed. In reality, it turned my woodworking project into a lesson in emotional resilience. Bit #1 snapped shortly after starting—cutting prime pine, at a gentle 1/8” pass, moving slow enough to make a sloth impatient. I had read the bad reviews, so I babied this thing like a museum artifact. Still broke. Clean snap, same spot as in the reviews. Thinking I just got a dud, I exchanged it. Bit #2 lasted a little longer (progress!), then snapped in the exact same place. For the record: no discoloration, no burn marks, no signs of abuse. This bit did not die bravely in battle—it simply gave up. At this point I was forced to get creative. Needing a small bit with a top bearing, I wrapped painter’s tape around a spiral cut bit and made my own DIY solution. Shockingly, this worked better. Yes, I had to replace the tape often and yes, this sentence should never have to exist in a review for a premium router bit. I truly wish this bit worked, because it seems to be the only one with these specs. Unfortunately, after two identical failures, I can’t recommend it unless your project involves learning patience, practicing returns, or exploring arts-and-crafts-level engineering. One star for ambition. Zero stars for durability.

Purchased this to use trim router for cabinet door hinges. Didn't look closely enough at specs. It cut well and clean into red oak but I only wish the 1/4 shaft was a tad longer to work better with my jig template. The shaft is only 1 inch long or about 2.6 cm

Worked as it should. I did notice it started to burn a little but I’ve been using it on hardwood. I think it’s done a great job for my use.

This tool is awesome. I could not have been successful without it. First, I roughed out the pockets to full depth in multiple passes with a .125 carbide upcut bit using an inlay kit guide without the bushing. Then I switched to this bit and completed the pockets in two passes (depth). Super sharp bit easily cut this end grain cutting board like butter. Highly recommend if you looking for precise controlled cutting for intricate designs. I also used the flush trim bit to create the inlay pieces on my router table. The results are stunning.

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!
