4 " DSR908MDesign Features of this bit Raptor cutters - Thermostable PDC cutters featuring an unique layer of thermostable PDC thatis 200% more heat tolerant and 400% more abrasion resistant than premium PDC. Thethermostable layer dramatically improves abrasion resistance by maintaining a sharp,slow-wearing tough cutting edge. When a wearflat finally develops. the thermostable layer wearsmore slowly than the multimodal polycrystalline diamond behind it , forming two sharp lips thatmaintain ROP. This allows the bit to drill significantly further and faster than premium PDC cutterbits.

Back Reaming Cutters - PDC cutters positioned on the back of the gauge pad or gauge backangle enable back reaming operations to be performed.

Hybrid PDC Bit - Diamond impregnated studs, set behind the PDC cutters, provide depth of cutlimitation. Typically used on the shoulder of the bit, the Hybrids improve lateral stability withoutcompromising rate of penetration.

TSP Gauge Protection - Thermally Stable Product (TSP) tiles and welded hardmetal gaugeprotection give both a highly durable and ultra-smooth gauge.

4 " R30AP Design Features of this bit RockForce Journal Bearing Precision finished journal bearing with silver plated thrustwasher and stellite inlay provideconsistent, superior performance in the constantly increasing demands of directional and verticaldrilling. Coupled with tight tolerances ball bearings, fully encapsulated in cone and journal delivermaximum cone retention at higher energy levels. O-Ring Seal - HNBR Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring seal. MudPick II Hydraulics Patented nozzle design directing a sweeping fluid flow directly into the cutting path at theformation failure zone. The most aggressive hydraulic arrangement to maximize cleaning andROP. SuperTuff Inserts Optimized carbide composition and insert geometries to maximize fracture toughness and wearresistance.

MatchFit Insert Retention. Patented process that captures entire insert shank, improving insert retention especially withlarge diameter inserts. TuffGage Maximum density of carbide heel inserts on heel of cone for added gauge protection. P Premium Shirttail Protection Protruding round top inserts for added wear resistance and improved stability without limitingannular flow area.
