Astra Info

Many of our tools are coated with a proprietary coating we have named  (HP-Astra). This coating allows higher speed & feed rates as well as extended tool life (up to 2x or 3x the tool life), plus increased lubricity in abrasive material. The Astra coating has specific ingredients like silicon, to help keep the bits clean as they are cutting or routing. The other ingredients that have been added, are to help keep the cutting edges sharper longer and not allow the bits to overheat as they are milling or routing.

By using our Astra coated router bits, you will avoid things like resin and dust build up on the cutting edge, which causes bits to get hotter faster, making them more likely to burn the wood piece or melt your plastic project. The benefit: Clean bits stay sharp longer because excessive heat breaks down the cutting edge on carbide cutters, which our Astra coating is designed to help with!
