Unusual but useful workshop tools

Air powered nibblers are a good hoot but the bits are vicious and get everywhere. You also need compressed air of course....

.

These are certainly 'unusual' .............. No idea what you would use them for though.

Drilling round corners perhaps.?

They are made from "common obtanium" as opposed to "unobtanium".

I have never seen a drillbit that wouldn't snap before becoming that sort of spaghetti impersonation. Are those chinese ebay seller making them of mild steel now?

If you abuse your tools you can't complain about quality.
Anyone who uses a cheese drill on metal is asking for trouble. They should be used only for making the holes in cheese.

May be better to have the shank yield rather than shatter, if only from a safety point of view.

IIRC, "genuine" Allen keys are claimed to twist in plastic deformation at least 1/2 a turn before the finally snap. There is also the possibility of stopping before snapping once you've spotted that the thing has gone plastic.Requires good control of the tempering process of course.

In the case of drills, you need most of the spirals to be hardened so you can resharpen them. Some of these cheese drills appear to be somewhat less than ideally hardened and tempered. They have the snazzy coating but beauty appears to be skin deep here. Where did you get them, Nick_G?

Oh they are not mine.

It's just a picture I saw upon another forum that I thought would provide a light note. Perhaps not the best place for me to have posted them as I don't want them to take the thread off topic from genuine interesting tools.

Dad bought a set of( "High Quality English Made" twist drills from an advertiser in the wood working magazine he subscribed to, they ended up just like the ones in that photo.
