Straight forward and easy to use. Did exactly what I wanted. I only do one oil filter a year.

As usual with Aircraft Spruce, my shipment arrived very quickly. The oil filter cutter was used shortly there after to open and inspect the guts of my oil filter following an oil change. The product is simple and intuitive to use and cleanly separates the top from base of the filter. Id forgotten, however, how much oil was left inside the filter. In the future, Ill separate the two halves inside a plastic bag!

Works very well. It’s larger and more heavy duty than it looks in the picture.

Worked great! Instructions say to put it in a vise but just holding it in my hands I had the filter cut cleanly in less than 30 seconds.

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.

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.
