Spiral Flush-Trim Router Bits，Solid Carbide Flush Trim Router Bit 1/4-Inch Shank Spiral Flush Trim Up Cut from TACKPRO (1/4 Shank Up-Cut)

We received the bit and put it in the router, the first one lasted a week, then broke. The second one has been going for about 2 weeks now. They are noticeably not as nice as our previous one we purchased from a different vendor. Will not purchase again.

Does a good job of clearing debris while cutting. I used it with a cordless trim router. Unfortunately the two I bought the bearing fell of the first day using it.

Trimmed without splintering

Get the other style. This one pushes the tool away. The other will pull it down.

I just used it today. For the money you can’t beat it very happy with it so far leaves a nice finish on the work peace.

Ive owned 4 or 5 routers and done quite a bit of work with them over the years (albeit not in a commercial or professional setting). Ive never seen a bit do this. I was cutting through soft cedar, moving reasonably slowly and SNAP! Scared the chocolate out of me. I see that most other buyers have given this product a good review, so its very possible that I just got a lemon. But this is my first experience with this brand of bits and it will certainly be my last. I would go with something more reputable. Your safety is not worth $15 in savings.

I ordered this bit in hopes it would give me a nice clean cut with my router table. First one spun the bearing off within the first two minutes of use. I ordered a replacement and the second one snapped in half and flew across the shop after trimming about 4 of 1/4 acrylic sheet. Avoid this one

This is a great bit. I got it to trim aluminum siding on a homemade teardrop trailer. It started out a breeze easily cutting through the aluminum... for about 3ft, then it started having all kinds of trouble. I about gave up on it but tried a few drops of cutting oil. Magic! For cutting aluminum use cutting oil often. Cuts like butter. I probably cut about 100linear feet so far. (I assume people who work with metal and routers already know this. I didn’t)

I had two of em and they broke very easily

I used this bit to trim 3/8 drywall around a door. It cut 4 ft of drywall then the bit broke in the center of the shaft. I didnt expect it to be ultra-durable, but this is terrible. Not worth the risk of the bit exploding during light use.
