A taper bit's primary function lies in its unique design. It features a non-uniform diameter along its length, with the cutting edge being narrower than the shank, resulting in a tapering effect as it drills into the material. The percentage mentioned in 'taper bit' refers to the angle or slope of the taper. For instance, a 1% taper over a 1-foot length would mean that the bit narrows by 1/100th of its starting diameter over that distance.

The cutting structure of a gold mining drill bit is typically composed of tungsten carbide inserts or polycrystalline diamond (PCD) cutters. Tungsten carbide is an extremely hard material that can withstand high temperatures and pressures, making it ideal for drilling through hard rock formations. PCD cutters, on the other hand, are even harder and more durable, capable of cutting through the toughest materials with ease.
