Tungsten Carbide Down Cut Spiral Router Bits

The tungsten carbide down-cut spiral router bits are designed to cut the working pieces from the top surface down to create a smooth edge at the surface. It makes effort to push down on the material being cut, and helps hold the material in place on the table surface. This bit is proffered by some users due to it packs the sawdust in the groove being cut, this helps hold parts in position and helps maintain vacuum when that type of hold down system is used.



The shortcomings of the bit are the packed sawdust is not automatically removed by the dust collector but must be manually scraped or brushed off . Also this bit is not appropriate for thermoplastics as the "packing" of the dust re-welds the parts together. When making "through cuts" the down cutting force can splinter the bottom face of veneered or other susceptible materials.
