Steel Body PDC Bits

8-1/2” S513U Adding value through performance

 

Design Features: • Cutters are strategically placed in 3D spatial coordinates

for maximum work rate efficiency, minimum cutter wear

and maximum penetration rate

• 3D designed 4140 alloy steel body CNC machined for

maximum blade and body strength

• Tungsten Carbide hardfacing in critical areas for increased

erosion and abrasion resistance

• TCI enhanced gage pads for increased gage protection

• Optimized parabolic profile for blade count, cutter quantity

and bit stability

• Force-balanced PDC cutter locations minimize bit whirl

and drill a precise round hole

• Asymmetrical blade design reduces drilling harmonics
