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

was a little apprehensive on the 1/4 shank size -- had been using a 1/2 shank but it got $$$ -- this bit worked perfect in a template routing project to cut a hole in the middle of a 7/8 piece of walnut -- took a little longer but one side of the hole is only 1/2 from the edge i think the smaller bite of the bite is better -- will order more

Spiral router bits make pattern routing easy and painless! These are good bits at a great price.

Great router bit did everything I expected plus more

This is a great bit. I got it to trim aluminum siding on a homemade teardrop trailer. It started out a breeze easily cutting through the aluminum... for about 3ft, then it started having all kinds of trouble. I about gave up on it but tried a few drops of cutting oil. Magic! For cutting aluminum use cutting oil often. Cuts like butter. I probably cut about 100linear feet so far. (I assume people who work with metal and routers already know this. I didn’t)

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

Broke the first time to use. Garbage bit

Does a good job of clearing debris while cutting. I used it with a cordless trim router. Unfortunately the two I bought the bearing fell of the first day using it.

Nice bit

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.
