Patent

CA 2570160

A drill bit is made from a shank, lid and blades. Junk slots with higher resistance to flow are provided to force drilling fluid between cutters on adjacent blades to improve cleaning. Blades are canted back, and openings at a high angle are provided to further enhance cleaning. The use of a lid facilitates high angle openings. The cutters may be made of sintered powder metal, and may include polycrystalline inserts. The blades may include a preferential conductive cooling material. The drill bit may include an enlarged hollow chamber and a relatively thin and long peripheral drill bit wall.
