I previously wasted my money on an automotive-type oil filter cutter. In order to use it, it required me to cut off the male fitting on my airplanes filter with a hacksaw, which needed great caution not to introduce metal debris to the filter element. It also cut the outer casing too close to the flange, making removal of the filter element almost impossible. This one makes it easy. Before use, it is necessary to change out the installed automotive cutter support to the longer one for aviation filter use, and the narrower guide for insertion into the aviation male filter connector. Both items are included with the cutter.

there is one part missing, this cutter works great, but you need the cutter, for automotive also, because some filters have different heights to them, all in all a great product.

Works well. Tip: Keep a little pressure on the top of the filter, towards the cutting wheel as the oil filter is turned. This keeps the wheel pressing against the side of the filter and tracking a straight cut.

Heavy duty, solid aluminum. The quality is what youd expect for a $46 tool

Works as advertised, includes the accessories required to adapt from female to male threaded filters

Perhaps I should have realized this beforehand, but the oil filters I need to cut have male threads on them that prevent the filter from sitting along the bottom of the tool so it can reach the cutting wheel. To cut a filter, as a result, I have to first hacksaw off the male threaded portion, which I have to be careful about to avoid introducing metal particles into the filter, so its not quite as streamlined a process as I expected it would be. Once the filter threads have been cut, the tool works well, but it is really designed for filters with female threads instead.

your service and shipping was excellent but it is not a very good product. Not easy to use because it doesnt have a way to hold the filter in the proper position. It did cut the filter but was not an easy task. When turning the cutter it comes off the filter.

Q: Where can I get a replacement cutting wheel for this Aviation Oil Filter Cutter?

We have the replacement cutting wheel listed in the "Accessories" tab on this web page. It is part number 12-21396 and is available to order.

Q: Will this aviation oil filter cutter work with the oil filters on a Rotax 912?

Yes, it will.

Q: Will this cutter open automotive oil filters?

We do not have any information on the use of this cutter with auto filters.

Q: Does this cutter come with an adapter to open filters with a male thread such as the CH48110-1 ?

This comes with a standoff that you would have to use to cut a male filter.

Q: How does this cutter work for male thread such as CH48110-1?

In short, the threaded stud on the filter is hollow, so one of the studs that come with this oil can cutter gets installed and hollow part of the threaded stud on the filter goes over the stud on the tool and then proceed as normal to cut the filter.
