Manufacturing Facility TomaHawk manufactures a full line of mud motors and mud motor components ranging in sizes from 1 11/16” to 9 5/8” O.D. We also offer custom designed parts and manufacturing to meet the needs of any customer. See our Product and Components page to view some of the standard products we offer.           Machine Shop Facility TomaHawk’s machine shop features manual and numerically controlled lathes and mills. Our air-conditioned facility ensures that our machine tools cut consistent, dimensionally accurate parts.   Welding Facility TomaHawk’s welding facility is equipped to lay tungsten carbide hard metal on wear pads, drive coupling lobes and stabilizers in addition to re-working worn drive couplings to return them to new condition.   Zinc Phosphate We also have zinc phosphating capabilities, which helps the parts to retain oil and lubricating compounds to prevent corrosion and thread galling.   Shot Peening TomaHawk has recently added shot peening to its growing list of manufacturing capabilities. Shot peening can be used to reduce surface cracking on parts with areas of high stress concentration such as threaded connections, radii, sharp corners etc. Shot peening bombards the surface of the part with steel balls or “shot” at just the right pressure and intensity. This traps compressive stresses in the surface of the material, which must be overcome when the part is stressed before a crack can develop.   Custom Manufacturing TomaHawk can produce custom designed components to fit pre-existing mud motors. With the use of the latest solid modeling, stress analysis, and CNC programming software, quality parts can be designed and manufactured quickly and accurately.
