Easily cut through those tough oil filter housings with the Oil Filter Cutter. This easy-to-use Oil Filter Cutter accepts both male and female styles of aircraft oil filters, and many automotive sizes. Simply place the filter flat on the cutter body, tighten the black knob to push the cutter wheel into the filter, and several turns will have you through the filter housing. Constructed of heavy-duty, aircraft quality aluminum, its effective design ensures a straight cut. Ball bearing rollers make it easy to turn the filter using the contoured knob—even with oily hands. The cutter accepts filters 3 1/8" to 4" in diameter, which includes most aircraft oil filters. Can be clamped to a workbench or held in a vise. All parts are replaceable.
