Bridging the gap between random orbital and rotary is the BigFoot LK 900E Mille Gear-Driven polisher.

This tool offers a balance of power, ergonomics, and capability for operators who prefer a forced-action movement but don’t want the unwanted risk or side effects associated with rotary polishers.

Unlike other forced action tools on the market, the innovated design of the Mille drives the rotation of the tool in a clockwise direction making the movement feel more familiar and comfortable.

Like all the tools in the BigFoot family, the LK 900E features numerous ergonomic touches to make it comfortable and efficient.


The BigFoot Mille uses a specially designed electric motor, developed in-house by RUPES, to allow for clockwise rotation of the tool movement.

This translates to an increased level of control and comfort for the operator.

Competitive tools feature counter-clockwise rotation which can increase unwanted lateral movement and fatigue for the operator.

The Mille also comes standard with two backing plate options (5 and 6inch) allowing the user to choose the pad diameter that best suits their needs or situation.


The new electronic speed control dial allows for easy adjustment of the top speed of the polisher without requiring the operator to move his hands.

The larger dial is easily adjusted with a move of the thumb.

High visibility numbers and a more positive feedback from the movement of the dial make speed changes feel more deliberate, allowing operators to select the ideal speed for the task without any interruption to the polishing process.

The module has also been tuned to deliver peak torque and speed in the optimal dial ranges.


Adding an additional layer of control is the new progressive trigger.

Acting as a throttle to control speeds within the dial range, the progressive trigger allows the operator to make subtle adjustments for precise control without interruption of the process or need to reposition the grip to access the speed dial.

The linear delivery of power allows for very fine adjustment within each speed range giving technicians a whole new dimension of control.


The Mark III comes standard with a 9 meter (29.6 ft) cord on both the LHR15 and LHR21 models.

The longer cord provides users enough length to move more effortlessly around their workshop or studio without the need for additional extension cords or searching for a nearby outlet.
