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.

Get the other style. This one pushes the tool away. The other will pull it down.

This bit works amazingly! First use was to cut some kayak hatch holes, this bit sliced through the plastic smoothly and had no chatter just a clean easy to guide cut. Ive also used it on some wood projects and it performs equally well leaving clean smooth cuts that need almost no sanding. Its also very sharp you can feel the cutting edge on the bit so be careful taking it out of the protective case. Im very happy with the performance so far and will be ordering more for my wodshop.

Whiteside quality at half the price

Cut 3/4 mdf no problem

First cut on router table cutting 1/2 MDF to follow my template it broke and ruined my template! Thank goodness the wood kept the bit from flying and no one else was around. Will not recommend.

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.

This not broke the first time I tried to use it. It is very flimsy and not for heavy duty use by any means.

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

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.
