The cutting edges of this router bit are made from high industrial grade micrograin carbide tips brazed onto a heat-treated high-carbon steel body thus leading to exceptional hardness and rigidity. Its cutting edges are radially relieved for a strong smooth cut in addition to avoiding rubbing and burning. It is precision ground, hardened, and tempered in order to stand up to a variety of materials. It is also equipped with wide open gullets for easy disposal of wood chips. It is suited for softwoods, hardwoods, chipboard, plywood and etc. Note : In order to avoid vibration and for maximum cutting quality, always choose a router bit with the shortest cutting edge and the shortest overall length available that is able to fit your project application. Excessive overall length may cause tool damage. In case a bit doesn't come with a speed chart. You may try the following suggestion. This is merely a guideline to start, result likely varies due to the varieties of edge and material hardness: Run 24,000 rpm maximum for 1" overall diameter router bits; Run 18,000 rpm maximum for 1-1/4" overall diameter router bits; Run 16,000 rpm maximum for 2-1/4" to 2-1/2" overall diameter router bits; Run 12,000 rpm maximum for 3" to 3-1/2" overall diameter router bits; ProductSiteLaunchDate : 2007-06-26T23:57:45.000-00:00 SupplierDeclaredDgHzRegulation : unknown UnitCount : 1 UnspscCode : 23241600
