What it is

Replacement grinding wheels for Casfuy nail grinders, listed for the N10, N30, N50, N60 and N65, and explicitly not for the N90.

Why the negative compatibility matters

Most spare-part listings tell you what they fit. This one also names a model it does not fit, which is the single most useful sentence a spare-part listing can contain — and it is the reason this part is worth a page.

Change it on performance

A grinding drum stops cutting long before it looks worn. When a job that took five minutes takes ten, and the nail warms up more than it used to, the drum is finished. Working on with a glazed drum is how animals learn to hate grinders.

Keep one in the box

A spare drum costs a fraction of the tool and removes the temptation to carry on with a spent one.

The questions owners ask

How do I know the drum is spent?

The job takes longer and the nail heats up more. A glazed drum polishes rather than cuts, and the heat is what makes an animal refuse the next session. Change it on performance, not on appearance.

Will it fit my Casfuy?

If it is an N10, N30, N50, N60 or N65, yes. Casfuy states plainly that it does not fit the N90, which is the kind of negative information that saves a return.

Can I use a generic drum?

Sometimes — the diameters overlap across brands. The failure mode is a drum that runs eccentrically, which vibrates, and vibration is exactly what animals object to. Test a generic on a spare afternoon, not on a nervous dog.
