About Us

We are a former cylinder overhaul shop with nearly 7000 cylinders of all makes and models  - including most, if not all radials - under our belt.  We used Borroughs Tools until those became unavailable. Combining several years of CNC machining experience and over 30 years of aviation cylinder and engine overhauls, we started an aviation reamer manufacturing business. We manufacture piloted HSS and solid carbide reamers and are developing new tools for the industry.

Our line is useful to the cylinder overhaul professional as well as the shop that wants to keep some cylinder repairs in-house.   

Once on our email list, customers will receive emails with updates on cylinder overhaul tools as they come on the market.
