What are these for?

Help identifying these would be appreciated. They are thread m10 on the end

Thanks Colin

Special made internal wrenches, but I can't imagine what for!

Thread insert tools? Can’t quite work out with the numbers on the one I can see, first ought they may be insert tools or tang break off but the length doesn’t equate or the long grooves on the diameter.

Internally threaded router bits.

Like these

I thought 'chipboard' straight away. Then wood work.

Hello,

Not sure they are router cutters, but they might well be "slot mortise bits," generally used in the furniture making industry, as opposed to the Joinery manufacturing industry.

I think the KITY range had a slot mortise attachment.

Mark.

The one in you hand has M10 on it, are they threaded for mounting?

They could probably be either, but those don't look (to me) like they have end cutting ability that I think a slot morticer would need (but there are probably more types than I know about).

M10 internal seems to be used on all sorts of industrial routers (hand or bench), morticers, etc.. Seems common for automated routers for PVC window frame construction.

Have a look for 'Rotox' cutters: (Example )

(Other makes using the same fixing are available).

Thanks everyone. So it looks like they are for wood working. I'll stick them on a shelf somewhere and forget that I have them!!
