The universal tool is for all calibers from .22 thru .338 cal. using standard (.080”) flash holes. This tool controls the cutting depth with a built-in stop that locates on the inside web of the case. A unique feature of this tool is the cross drilled hole for chip relief. Uses standard pilot stops for 3/16” mandrels.
