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)

I have already used the hell out of this little jewel! If you are cutting out patterns and going against the grain in corners and on protruding edges, this jem really reduces catching on end grain and chipping out. Priceless addition if you do alot of cutouts for inlay work!

Cut very clean and without a lot of drag on the router motor...this is partially due to the small diameter, but also a sign of good design and sharp cutting edges.

You will be lucky if you can get through your first cut without the bearing spinning off and ruining your work.Avoid like the plague.$65 down the tube.They have a nerve selling this crap.

The bit was packaged well and protected against damage. Upon initial inspection one of the two guide bearings was not spinning freely. It had a catch similar to a bad bearing. After the first use it was obvious the bearing was bad as it was marring the template. The bit cut very cleanly and overall meets the price point in comparison to some other name brand tooling.

Trimmed without splintering

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.

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.

Worker better than perfect

Clean cut. Good tool

This was a great bit for a time sensitive project but buyer beware the ring the holds the 2 top bearings on is only a press fit. with that being sad you can imagine the small ring will eventually come loose. The press fit is not tight and after a 5 mins of use the ring flew off and the bearings came loose. thankfully I caught this before it ruined the piece I wasnt working on or this review would be alot more negative. I knew this upon inspection of the bit when I received it but I didnt have many options so I gave it try. the bit is VERY sharp and cut through the materials with ease but I dont know how long this will stay sharp. all in all good priced product but again you get what you pay for.
