E-Force Controller

The Controller

The E-Force controller is sleek and simplistic by design. The small foot print leaves more space at the workbench, and it is easy to carry and move around the shop. Dual input ports connect up to 2 motors. Select between motor A and motor B (only 1 motor will operate at a time).

The digital display shows the RPM speed in 1,000 RPM increments, and the Load meter illuminates when the operator is using too much force.

The Solid Handpieces

The solid handpiece is lightest and smallest handpiece in the E-Force line. Available with 20K or 40K adjustable speed motors, the solid handpieces are best suited for long duration applications and when changing heads is not necessary. The motor casing has several air slots and a cooling fan that allows heat to escape which helps prevent overheating. At the base of the motor is a multi-function switch that will turn the motor on or off and adjust the variable speed of the motor. Comes with a 1/8” collet & 3/32” collet. 3mm collets are available separately.  Limited 6 month warranty for defective parts only.
