    Designed for use on the Mark V Models 500, 505, 510 and 520, the Speed Reducer provides a 7:1 speed reduction ratio. So, instead of its usual 700 to 5200 rpm speed range, your range increases to 100 to 5200 rpm. As a result, you can now perform even more operations while improving safety and increasing your ability to achieve top-quality results.  

    With the Mark V set at its lowest speed setting of 700 rpm, the Speed Reducer output spindle will be turning at only 100 rpm ! As you increase the speed of the Mark V, the Reducer's rpm also increases at a 7:1 ratio. This provides new levels of speed reduction for whatever operation you are performing... turning, sawing, drilling or boring  

    Now, you can drill metals, plastics and large diameter holes in the hardest woods with the Shopsmith Speed Reducer. Use Forstner bits, hole saws and large multi-spur or clockface bits with improved results, added safety and less burning of the bit or the workpiece.
