- Type of bitDiamond
3 3/4" x 4 1/8" TO 14 3/4" x 17 1/2" (95.25 mm x 104.8 mm TO 14.34 mm x 444.5 mm) - In Matrix Varel’s bicenter bits are designed to enlarge the well bore, drilling 15 to 25% larger than the pass through well bore in all types of PDC drillable formations. The bicenter bits are used to increase lateral diameter, to replace under reaming, to help control trouble zones, and for expandable tubulars. The matrix material construction resists erosion and abrasion found when drilling oilfield applications. The one-piece design shortens the overall bit length for better directional control. Varel bicenter bits also have an innovative force balanced cutting structure which minimizes cutter and casing damage when drilling out. Additionally, Varel’s unique design minimizes bit vibrations often experienced with conventional hole opening tools thereby resulting in longer downhole tool life and reduced drilling costs.
