New Bit Lines Have Advanced Design Features


Varel International has launched the new Raider series PDC drill bits, along with new bit technology for horizontal directional drilling (HDD) applications.

According to the company, the new Raider bits are purpose-built for drilling to total depth through interbedded soft and hard formations of transition zones. By incorporating design refinements that create a new, more balanced profile with greater stability, the series provides a solution to overcome the ROP and durability challenges associated with these applications. Varel also said its Target HDD technology encompasses a new series of roller cone bits equipped with EdgeGuard shirttail enhancement technology, as well as Full Coverage (FC) cutters for use on hole openers and reamers in HDD operations. The roller bits, available in both open and sealed bearing configurations, are equipped with patented High Energy Tumbled inserts.

The series’ FC cutters are sealed bearing and compensated components with advanced cutting structures for outstanding performance in hole opener and reamer applications. All FC cutters feature Varel’s labyrinth seal ring protection for extended life.
