A Selection of Equipment of Use in the Production and Maintenance of Aircraft, Missiles, Space Vehicles and their Components. The PERA Reamer A research report recently issued to members of the Production Engineering Research Association describes the design, performance and principal advantages of a new type of reamer designed and developed by PERA.t Outstanding improvements in the quality of reamed holes at greatly increased production rates, and longer reamer life, can be achieved with the new reamer. The potential financial savings are, in consequence, very considerable. For example, it has been estimated that a medium‐sized engineering works could save over £2,000 a year by using the PERA reamer.
