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 pur-pose-built for drilling to total depth through
interbedded soft and hard formations of
transition zones. By incorporating design
refinements that create a new, more bal-anced 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 technol-ogy, 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 configura-tions, are equipped with patented High
Energy Tumbled inserts.
The series’ FC cutters are sealed bearing
and compensated components with advanced
cutting structures for outstanding perform-ance in hole opener and reamer applications.
All FC cutters feature Varel’s labyrinth seal
ring protection for extended life.
