Holcutter™ Speed Reducer

The Speed Reducer is for large diameter Holcutters or for all sizes when drilling thru stainless steel to improve tool life. It slows the RPMs down to a more effective cutting speed using a 4:1 gear ratio. The Speed reducer can be mounted directly to a 1/2″ drill (pictured) or mounted in a 1/2″ chuck using the triple-flatted adapter (04943). Holcutters mount directly to the Speed Reducer using the Quad-Lead Thread System.

These are just starting points and speed may have to be adjusted accordingly. For Metric Cutters use closest fractional size.

For longest tool life and best performance, always use Lubricant.
