Flush Trim Router Bits Top Bearing Router Bit 1/4" Shank (4 Sizes)

I'm kind of shocked that these are as nice as they are. Router bits are HORRIBLY overpriced, and these were just what I was looking for. They are really durable. I've used them a lot and they are still sharp and still work perfectly. I'm very pleased.

Top bearing router bits are not that common (and I am confused whether these should be considered bottom bearing since the tip of the bit is the top, but the picture shows you what you are getting). If you need to route to a certain depth while using a straight edge or a template against the bearing, one or more of these may fit your job, but don't expect great accuracy. There are problems with these 1/4" shank flush trim bits in general. The longer the cutting surface of the bit, the more vibration and grabbiness of the bit. You can progressively lower the bit only until the mandrel gets in the way. Partially inserting the shank in the mandrel can result in the bit being pulled out and destroying your work piece. The bearing consistently mars the template or straight-edge. The larger diameter bits with 1/2" shanks tend not to do this as much and stay sharp longer, but they are about 3 times as expensive. Flush trim bits with a bearing at the tip end can only be used to trim edges and cannot do plunge routing inside a template. Routing against the grain can produce unpredictable and sometimes dangerous results.

I have already used these router bits on one project -- in pine and in oak. They leave a clean cut and the chips they produce are characteristic of a good, sharp router bit.

Bought these for a east trim job on a guitar build. All it did was tare up the sides of my wood and mess everything up. I have bought some that looked just like these before, and they worked awesome. But these a 100% garbage.

What can I say, I got four for the price of an expensive one. I used one of them so far and I was expecting a terrible finish but it went really well except because it left some lines of what I assume was the bearing, but I dont care I can sand that off or put some paint on it and make it part of the design. I'm very satisfied so far, for being a cheap router bit, it performs really well.

The 1-1/2 inch bit worked fine for me. However, I ordered 2 sets of bits and when I received them, I got 1 full set and only 3 of the second set. The 1-1/2 bit was missing.There was a small slice in the packaging just above the place where the bit would have been. I didn't take the time to mess with chasing it because I was really busy.

Used the bits to remove wood for a Dutchman repair. I used a template for the router and found the bearings for the bits to be accurate such that the template was not cut by the bit.

They just arrived, so I cannot say anything about durability. I will return later for that.I only checked accuracy of the diameter, so I cannot say any more about the other dimensions. All literature is metric and my project is imperial, so I have not converted yet.
