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 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.

Bought this bit for routing 1/2 plywood from door and window openings with a Makita cordless router when were framing. It works great but you have to pay attention. It will grab pretty easy and want to get away from you. I would recommend this bit to anyone. Definitely worth the $$$ compared to a Whiteside bit.

Shipping to South Africa is a nag and takes forever but product is exceptional.

First cut I used it was amazing, then when I did my second cut the end of it heated up, Im not sure if it was a bearing or not as it doesnt spin now and not sure if it did before, but it discolored the bit. Im really sad about it because my first cut went so well. Also I was cutting 3/4 mdf applying very little pressure to the bit trying to let it do all the work

Cut 3/4 mdf no problem

Great product

Didnt last. Used it twice and it was done.

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

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

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.
