I recently received a Sinclair deburring tool holder. It will accept the Forster, Wilson and Redding deburring tools. You simply insert the deburing tool of your choice into this holder, tighten it with the hex screw and attach it to your cordless screwdriver to deburr the inside/outside of your case necks. You could formerly do this task with the deburring tool directly into the screw driver but could not do the outside of the case necks. This does a good job and is relatively speedy. You do not want to attach it to a standard drill as it is much to fast for the task. Best wishes.
