Diamond Edge Bits

What is the Diamond Edge drill bit?
The Diamond Edge is a patent pending PDC drill bit designed to run at high penetration rates even in applications that call for higher blade and cutter counts. Its unique cutting structure layout adds another dimension to bit stability and smooth running by combining the penetration rate potential of traditional "single set" cutter layouts with the life extending features of a "plural set" cutter layout. The result is a bit that runs up to 20 percent faster than conventional PDC bits with minimum bit wear.

How does the cutting structure work?
With Diamond Edge, Varel has extended the advantages of an asymmetric blade cutting structure in the control of bit vibration by adding precisely defined plural cutter blade asymmetry. This proprietary approach enhances both stability and penetration rate. You get more out of the bit, and more out of the diamond on the bit.

What are the benefits of the new design?
Diamond Edge bits work across an extended range of weight on bit, penetrating quickly even at low bit weights in softer rock. When formations firm up, the bits can take added weight with a smooth torque response and maintain higher than competitive rates of penetration. The technology is a departure from traditional plural set bits that require higher weights to drill even in soft rock, and are generally durable, but slow, even in harder rock. Traditional plural set bits also can produce an erratic torque response when taking additional weight.
