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)

Used this to trim some veneer on speaker cabinets. Half way through the second one, I noticed a line in the veneer. Turns out that the bearing was dragging. I could feel when I spun the bearing by hand that it was getting hung up. I can’t recommend this

They hold up pretty well we use on mdf all day. Last about a month

No a good quality at all really bad I work on a carpentry shop building fine furniture and we used a router every single day this one so far has been the worst

Product broke during first use

Been using it to route tabs off CNC cutouts and works great for that purpose.

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 like the way it cuts

I broke the first bit that was sent to me, but its because I didnt understand exactly what part of the bit could actually cut. At the top of the bit (the end that connects to the router), its solid cylindrical metal until you get to the point where the spiral groove starts to be cut into the shaft. That area cannot cut through the wood. Its not until you get a little further toward the bearing end that you get to the actually cutting area of the bit. I didnt realize this and was trying to cut plywood partially with that non-cutting area. It took a lot of force and ultimately the bit broke. Now that I understand, my replacement bit is working great. Ive seen a couple people complain about breaking bits, and I have to wonder if they did the same thing I did. Prior to this bit, I was using a 1/2 straight bit. It did the job, but it was a lot more work pushing it through, and the resulting cut was kind of rough. Needed a good deal of sanding. With this spiral bit, the cut is smooth as glass.

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.

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
