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)

Bit snapped first time using it. Wasnt even going through material fast, it just snapped. Save your money and look somewhere else.

Less than 10 seconds into my first cut with pine plywood and it snapped in half. Very poor product

It broke the first time I used it.

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.

The bearings disintegrated very first time using it, almost hurting me. I don’t recommend at all

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.

The bit cuts well and leaves a smooth surface ,

I needed a small diameter router bit for trimming 1/2 plywood. This product is fabulously sharp and very easy to use. Highly recommended!

Lasted about 30seconds cutting big box store birch.

It’s okay for the price. Ended up wearing out and getting dull and tearing out the wood after repeated cuts on soft wood. Ended up going through 3 of these just to finish the job I was doing.
