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)

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.

This trim router bit broke off in the collet of my router - the rotating bit went flying through my shop - thankfully, no one was hit by it as it is very, very sharp. Have been using routers in the shop for years, including flush trim router bits and have NEVER seen anything like that before. Not only low quality but very dangerous.

WORKS GREAT with my dewalt drill. Easily cut through drywall and 1/2 inch plywood. By far a great investment. Used for 2 days straigh and bit is still sharp. Cuts are clean and concise.

The bit snapped in half during first use. Still not able to find the other half. No injuries, so could have been much worse, but not impressed.

Nice bit

I use it for routing 3/16 beadboard. Waaay better than the formica bit I was using.

Clean cut. Good tool

Using this bit in a router table with adequate dust collection. The top cut is nice and clean, but the underside cut is ragged. Even with the dust collection, it throws a lot of these shredded wheat shavings around. Causing me to have to stop and vacuum after every cut. Not great for time management. More expensive bits do not do this. For the money, it is sharp, it does cut and it gets the job done, but it adds time when you have to sand edges and clean up the mess.

Perfect for what I needed. Cut was clean.

This was the perfect bit for my job. Cut out 10 window openings and it’s just getting started.
