Woodworking cutter blade

[ms08]

I am asking for friend who is trying to source a replacement blade for what is a nibbling tool fixed into an angle grinder. It is just under two inches in diameter.
Does anyone know it's technical name or where it could be sourced - no markings on it other than limited to 20,000 rpm....

Many thanks

Probably called a 'wood carving disc'

Arbortech make them + loads of Chinese copies.

This is a bigger one:

Arbortech Turbo Scraper

The Arbortech TURBO Scraper™ is the ideal choice for woodworking projects that demand precision and accuracy Think of this powerful disc as a turbocharged upgrade to a conventional hand scraper. Specifically engineered to cut at a negative angle, it...

IIRC there was a hoo-hah a few years ago and similar discs were banned on safety grounds (the ones with chainsaw teeth on the periphery, but it may have been broader - You can still get them on Amazon though!)

It doesnt look like a nibbling tool blade to me (for metal), as Misterg says it looks like a cheap knock off of the arbortech woodcarver.
There were a lot of these with chainsaw chain welded to a disc & they were rightly banned, too many bad accidents with people chomping big lumps out of themselves. The arbortech gear is much better designed with antikickback humps between the teeth etc & negative rake teeth.
Some of the cheap chinese copies were lethal & a violent kickback was a real possibility. I have an arbortech one with the three carbide teeth & it is a scary tool to use, the blade is quite heavy & it removes wood at a terrifying rate, it has a supplied guard that really should be used but not many do.
I dont use mine often at all, its one of those tools that sits in the back of the cupboard & best place for it.

As above, Arbortech are the original and best. Be wary of the clones.

Review of some options here:

Another outside possiblity is one suggested elsewhere by 8ob, a 'carbide cluster blade'.

There is a variation of those carving discs that use carbide inserts and if I was buying one thats what I would choose.
The arbotech ones use a fixed carbide blade and when it gets blunt it is a proper pain to sharpen.

Thanks for the replies - not sure how old the blade is but will point him in the direction Arbortech tools - he uses it for getting into tight spaces/curves when carving animals.

Arbortech also do a mini version that could be useful for this. See their website.

The Arbortech disc i have has replaceable circular teeth that can be rotated & changed if necessary. Held in with a torx fastener.

Didn't know that Arbortech did them too. Only saw the Chinese ones on aliexpress.

Looks like a lot of the hand held biscuit cutter blades that are used for cutting slots in edges of boards etc & inserting super dry beech biscuits & wood glue .

IIRC my biscuit cutter blade is 100mm in dia with tungsten cutter tips

eBay item number:236109976213 for a genuine Einhell refurbished blade for a tenner each .

i just touch all of my carbide cutting blades up on the grinder using a green stone . only takes a few minutes just on the tips it dont have to be that accurate your only taking a midges d,ick off

The image shows 6 chainsaw type teeth, 3 turned up, 3 turned down. It's not carbide teeth.

It should presumably sharpen up alright if you follow chainsaw geometry.
