The Signature Series Precision Cordless tool line is capable of specifically programming the running RPM into the tool within its range of operation. Each tool in the range has an integrated Mini USB connector that couples to the Signature Series Programmer module. Simply connect the tool to the Programmer Module and flash the tool to the desired RPM. Once flashed, the tool will hold the RPM setting until a change is desired and it is re-flashed. New tools, that have not been specifically set by the programmer module, will run at their maximum rated RPM as shown in the catalog table and on the tool label.
