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)

Whiteside quality at half the price

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!

I used this bit to trim 3/8 drywall around a door. It cut 4 ft of drywall then the bit broke in the center of the shaft. I didnt expect it to be ultra-durable, but this is terrible. Not worth the risk of the bit exploding during light use.

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.

Bearings failed third time using it. Edit: Bit was replaced and no problems yet.

Bearings came apart after just a few uses. Switched to a Diablo flush bit 3 flute and that’s been working strong weeks now. I bought three bits from you. All three the bearings came off.

I like the way it cuts

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.

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

Great router bit did everything I expected plus more
