Services & Sales Overview


Whether you need a single part machined or a turnkey solution, THI is prepared to handle it. We’re experts at jobs large and small, and treat every project with the same commitment to quality and service.



THI has always maintained that your part must be straight to service it. We provide an experienced staff and presses with the tonnage necessary to accomplish the job. We have more in-house presses available than any other firm.



At THI, we’ve continued to re-engineer our equipment and tooling to provide a broader capacity of drilling services than any other firm. From a .125” hole and 6” in length to a 12.5” hole and 309” in length, we provide a consistent level of service to meet all the needs of our customers. Our capabilities in drilling services allow us to provide extremely quick turnaround.



Honing is our primary business at THI. We have more spindles, more sizes and more capacity than any other firm. Whether you need something honed as small as .590” or as large as 26”, whether the part is only 6” in length or 720” in length, we have the tooling to meet your needs.



To meet the needs of our customers we offer various trepanning services. From a 1.75” hole to a 12.5” hole, we can service any part up to 360” in length.



At THI, we’ve continued to re-engineer our boring equipment and tooling. We’re prepared to meet all of our customers’ demands with boring capabilities as small as 2” and as large as 28” (up to lengths of 30’).
