Sealed bearing rotary bits for high-performance blasthole drilling. Available in versions with roller (AVL) or journal (AV) bearings to provide longer bearing life. The external features of Avenger™ drill bits are carried over from both Ridgeback™ and D-Force™ drill bit series. Thereby, each Avenger™ drill bit is optimized for drilling in hard rock or abrasive formations, providing maximum Rate of Penetration and wear resistance.
AVENGER bits bring together the best of patented features, knowledge, and experience to produce improved ROP, lower Total Drilling Cost and extended bit life. With two sealed bearing packages available and shared cutting structures there is a bit for your application.
HET CARBIDE TREATMENT
The patented High Energy Tumbling™ (HET) method produces a unique cutting structure surface toughness that extends bit life and increases drilling rate.
SEALED JOURNAL BEARING (AV)
Designed for moderate to ultra-high pull-down applications where extended bearing life is required. In addition to the patented conical seal gland, the journal design also features a patented heat shield to prevent thermal degradation of the seal.
ENHANCED CUTTING STRUCTURE
Designed to provide the highest penetration rates and the longest life available.
SEALED ROLLER BEARING (AVL)
Designed for lower to medium pull-down applications where the ground conditions limit the bearing life of standard open bearing bits. The patented conical seal gland extends seal life
