Shear angle:

The axial angle applied to router bit teeth provides a gradual “attack” on the work piece, thus guaranteeing improved advancement and a better finish.

Anti-kickback shoulder device:

The original anti-kickback shoulder device on the router bit body limits the possibility of kickbacks due to overfeeding. It is especially effective when using the router bit on router with manual feed.

FlaiArmor® Coating:

The FlaiArmor coating features the following benefits: it is not harmed by any chemical compound, it is completely insoluble in water or solvents, it has excellent surface lubricant characteristics, it is anti-adherent, and it diffuses and disperses the heat generated
by friction in the cut.

Sharpening:

 A knife, regardless of what material it’s made of, will not cut if it is not sharpened. The same is true of router bits. If the teeth are not sharp, the tool will not cut. Experience shows that the sharper a tooth is, the longer its cutting edge will last.
