The double-diamond combo tool is manufactured from high-strength alloy steel as a single-piece tool. It is an extremely effective bottomhole stabilizer where severe crooked hole tendencies are encountered.
The unitized construction features two sets of three-blade spiraled ribs designed to reduce damage to the hole wall and ensure maximum fluid circulation. Optimally spaced diamond-enhanced inserts (DEIs) provide the reaming action necessary to keep the hole in gauge.
The inserts are brazed into the tool body, ensuring dependable service and complete repairability. Type 300 hardfacing provides optimum wear resistance and stabilizer blade life.
The increased hole wall contact area enables more drilling weight to be applied, thus improving penetration rates while staying within acceptable deviation limits.
