AOOSEDOO Oil Filter Cutter for Canister Filters — Aluminium tool fits up to 5-3/4" diameter, replaceable blade

The AOOSEDOO Oil Filter Cutter is an adjustable aluminum cutting tool that cleanly opens canister-style oil filters up to 5-3/4" diameter for quick interior inspection.

When you need to see what a used oil filter trapped—metal shavings, sludge, or contaminants—this purpose-built cutter gives a clean, controlled slice so you can inspect the element and make informed maintenance decisions. Built from 6061-T6 aluminum with a sharp replaceable blade and a disc-shaped support platform, the tool is designed to hold common car, truck, boat, and small-engine filters steady while cutting, reducing mess and minimizing effort.

How does this cutter make cutting oil filters easier?

The cutter’s disc platform centers and supports the canister so the filter won’t shift during cutting, and the spiral feed rod drives the blade smoothly around the circumference. A precision blade requires only modest torque to slice through the casing, producing an even opening for inspection.

• Disc-shaped platform for secure, centered support
• Sharp, purpose-made cutting blade for smooth cuts
• Thick spiral rod resists bending under torque
• Adjustable clamping range for many filter sizes

What sizes and filter types are compatible with the tool?

The AOOSEDOO cutter adjusts to accommodate canister-type oil filters from approximately 1-3/4" up to 5-3/4" in diameter, covering most automotive, marine, tractor, and small aircraft piston filter sizes (with noted preparation). Scales on the body are reference marks and do not affect function.

• Fits common canister oil filters 1-3/4"–5-3/4" diameter
• Suitable for cars, trucks, boats, tractors, and many small engines
• Aircraft piston filters require removal of the central stud before cutting
• Scale on tool is for reference only

How durable and serviceable is the cutter?

Manufactured from lightweight, oil-resistant 6061-T6 aluminum, the cutter resists corrosion and stays rigid under use. The spiral feed rod and blade assembly are built to withstand repeated twisting; blades can be replaced when dull to keep cut quality high.

• 6061-T6 aluminum body for strength and corrosion resistance
• Robust spiral rod resists bending during operation
• Replaceable sharp blade for continued performance
• Compact, lightweight design for easy storage and transport

What comes with the tool and how is it used safely?

The package includes the AOOSEDOO oil filter cutter and a double-ended AN wrench to assist with adjustments and operation. Use steady, controlled rotations and secure the filter before cutting; remove any filter studs on aircraft piston filters first and follow basic workshop safety—gloves and eye protection recommended.

• Includes cutter and a double-ended AN wrench for adjustments
• Secure the filter on the disc platform before cutting
• Remove aircraft piston filter stud prior to cutting
• Wear gloves and eye protection for safe operation

Who is this for: The AOOSEDOO Oil Filter Cutter is aimed at home mechanics, professional technicians, fleet maintenance teams, marine mechanics, and hobbyists who perform routine oil analysis or want a clean, reliable way to inspect canister-style filters. If you need a portable, durable cutter that handles a broad range of filter diameters and simplifies filter teardown for inspection or diagnostics, this tool is designed to deliver consistent, low-effort cuts with minimal mess.
