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)

Purchased 2 bits to router out Corn Holes. The first bit didnt even make a full circle and snapped in 2 pieces. The 2nd bit made the first hole, and I started the 2nd hole and it snapped. These are complete garbage, their durability is complete junk.

Used it to cut plywood out in window opening made it 2 inches snapped but it was a quick 2 inches. Disappointed to say the least.

The bit was packaged well and protected against damage. Upon initial inspection one of the two guide bearings was not spinning freely. It had a catch similar to a bad bearing. After the first use it was obvious the bearing was bad as it was marring the template. The bit cut very cleanly and overall meets the price point in comparison to some other name brand tooling.
