Product Overview
Cutting open a used oil filter can reveal metal, bearing material, sealant, or other debris before a small warning becomes a major engine failure. It is useful after a rebuild, during racing maintenance, after a low-oil-pressure event, or whenever the filter’s contents matter.
The cutter supports the filter body while an adjustable cutting wheel slices the shell without sending abrasive saw debris into the media. It is an inspection tool, not a can opener for pressurized or hot filters. Drain the filter completely and use hand and eye protection.
Key Features & Performance
- Adjustable range for 2-3/8 to 5-inch filter diameters

Frequently Asked Questions
Q: Why cut a used oil filter open? A: The media can show metal or other debris that helps assess internal engine condition.
Q: Does the tool fit filters larger than 5 inches? A: No. The listed working range ends at 5 inches in diameter.
Q: Will a hacksaw give the same result? A: A saw can add its own metal debris, which makes the inspection harder to trust.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
