Andis Clipper Blades: Systems, Fit and Replacement

Detachable blades snap off and on by hand. Each blade is a fixed size and you change size by changing blade. This is the standard on grooming machines and on several professional clippers - the UltraEdge and CeramicEdge lines are the ones you will see most often.

T-blades are wider and squared off at the corners, which lets the clipper cut right up to a line. They fit trimmers built for them and are not a substitute for a standard blade on the same machine.

Adjustable taper blades are bolted on and move with a lever on the side of the clipper, changing cut length without swapping parts.

A quick test: if the blade comes off with thumb pressure and no tools, it is detachable. If changing it means a screwdriver, it is a taper blade.

Both are detachable and share the same mounting, so a machine that takes one takes the other. The difference is the cutter material.

UltraEdge is steel throughout - the workhorse, and the cheaper of the two to replace.

CeramicEdge uses a ceramic cutter against a steel still blade. Ceramic runs cooler over long sessions, which matters if you are cutting for hours, and it holds an edge longer. It is also more brittle: a dropped ceramic cutter is far more likely to chip than a steel one.

For occasional use at home, steel is the sensible choice. For a machine running most of the day, the cooler blade earns its price.

Third-party blades sold as Andis-compatible are common and considerably cheaper. Quality varies: some are ground properly and cut indistinguishably from the original, others sit fractionally off and show it as pulling on one side or a blade that heats faster than it should.

The risk is manageable on a home clipper and less so on a machine you rely on. Be wary of listings that claim compatibility with several brands at once - those are built to a common mounting pattern, which is not the same as being made for your clipper.

Most blades that get replaced were not worn out. Work through this first:

• Oil it - a few drops across the teeth with the clipper running. A dry blade pulls, heats and sounds harsh, and oiling fixes it in seconds
• Clean underneath - on a detachable blade, take it off and clear the packed hair between cutter and still blade
• Check alignment - the cutter should sit slightly back from the tips of the still blade and be square across
• Check tension - too loose and it chatters, too tight and it drags and overheats

If it still pulls after all four, the blade is genuinely done. Detachable blades can be professionally resharpened, which is worth doing for a ceramic or a good steel blade and rarely worth it for a cheap one.

Anyone cutting regularly benefits from a second blade in the size they use most. Blades run hot in continuous use, and swapping to a cool one is how professionals avoid burning the animal or client - and it doubles the interval between sharpenings, because heat is what takes the edge off.
