CompassTM Series Slimhole Bits 
Reduced size casing programs, re-entries, multi-laterals, and coiled tubing drilling all require steerability, reliability and efficient r
ate of penetration. Engineered with application specific technology, the new Compass Series Slimhole Bits provide excellent steerability and high rates of penetration even when weight on bit is limited. The bearing provides long, reliable performance in deep hole, long reach sections where increased RPMs in motor applications are commonly encountered.
Series Features and Benefits
› Advanced cutting structure and gage
Compass series bits are made with highly responsive cutting structures designed for increased drilling speed and unsurpassed steerability. The dense shirttail protection included in the gage of slimhole bits provides superior durability in directional applications. Custom gage row designs are available to optimize the bit for specific drilling applications. Semi-round top (SRT) inserts or flat topped diamond inserts are applied to harden the gage where required.
› Patent pending conical seal gland
Constructed to resist cuttings packing in the seal area, the unique geometry of the seal gland provides significant benefits during high angle drilling.
› Patent pending heat shield
Deployed between the seal and inner bearing, this shield provides life extending thermal insulation to the seal from heat generated in the bearing.
› High temperature, high lubricity bearing grease
Advanced synthetic grease allows for improved lubrication and greater reliability in high speed motor applications.
› High capacity reservoir
The redesigned reservoir is capable of delivering bearing lubrication over longer and higher RPM runs.
› Patented High Energy TumbledTM (HET) cutting inserts
Cutting elements undergo the HET process to alter the surface attributes, resulting in inserts that are more abrasion and impact resistant.
› Advanced bearing metallurgy
Compass bits are equipped with a silver plated journal bushing, silver plated floating thrust washer, pilot pin and enhanced bearing hardmetal alloy for increased durability and reliability.
