3D REAMER MODEL 2020
For Hard and Extra-Hard Formations
Available in three body types and four cutter faces, the 3D Reamer/Stabilizer Model 2020 is a “workhorse tool” proven in the toughest drilling.
The Near-Bit, 3-Point is furnished box-down for make-up with the drill bit and ensures the hole diameter is held to full gauge even as the bit wears. This eliminates reaming part of the way when a new bit is tripped downhole.
The Near-Bit, 6-Point has two sets of cutters staggered in relationship to each other for extra reaming capacity. This type helps prevent sharp deviations in packed hole assemblies, and is ideal for conditioning the hole prior to running casing. The String, 3- Point type is provided with pin-down and box up for placement with in the drill collar string. This type not only reams but also centres the drill collar string for faster bit penetration, more positive deviation control, and helps avoid differential sticking.Strength
3D’s one-piece weldless body construction utilizes a proprietary chrome-moly alloy that is exceedingly strong. After machining, the body is fully heat-treated and historical records are kept on the metallurgy of all parts.Availability
The Model 2020 is available in body sizes for a reaming 20 hole sizes from 5 5/8” thru 28”. Custom options include 9-Point configuration, slabbing between cutter pockets for better annular flow, tungsten carbide hardfacing on wear surfaces of the cutter assembly bushings, and protective tungsten carbide “wear pads” welded to body between lower cutter bushings.
