Allis Tool has 6 Turning Centers (lathes) with live tooling that can accommodate different sizes ranging up to 35.43” in diameter to 126.00” long. Allis Tool also provides all necessary secondary milling and grinding operations offering customers surface treatments with CMM reports.


The bigger, the better. Bring it on. We’ve got CNC machines at our disposal to create absolutely anything. Think wind turbine housing, construction equipment and turbomachinery. Applications in the oil & gas, aerospace, and medical industries. High power, tight tolerances.

Short Run

A local motor cycle giant and power generation company utilizes Allis Tool & Machine Corp. to prototype machine engines, cast iron transmission blocks, shredder rotors, gear housings or master slips for oil rigs. We set up the machining process on your floor—for you. This isn’t the end of it—beyond our primary services, we also perform a plethora of miscellaneous services, including drilling, boring, tapping, reaming, necking, knurling and a host of other highly specialized machining tactics.


Allis Tool & Machine Corp's certified welders fabricate light to medium gage weldments. Hard facing of wear parts is where we specialize. A high percentage of the jobs fabricated at Allis Tool are finish machined. Why? Because nobody does it better.


Allis Tool & Machine offers high-quality surface grinding, internal grinding, and cylindrical (ID/OD) grinding services. Our grinding services achieve unsurpassed dimensional accuracies and surface finishes for demanding applications.


Our impressive vertical machining centers are capable of milling components 12 feet long and 8 feet wide. Three and four axis machines mill, drill, bore, broach, thread and face tough metals like titanium, zinc and iron into carefully crafted large CNC parts.


Our journeymen toolmakers have an organized method of disassembly, carefully noting wear parts that require rebuilding and/or replacement. Rebuilding older equipment often costs less than full-blown replacement. Allis Tool & Machine capabilities make us the industry standard for equipment repairs.

Wire EDM

Our specialization lies in the production of large, heavy, and complex components in volumes of about 1 to 300. We employ a state-of-the-art 4-axis Mitsubishi wire EDM machine with an integrated automatic wire threader system to reduce setup time and, in turn, production time and cost.
