Re: What's this called?

Next up on 'What's it Called!? the big red gnarly thing.



I want some more of these, but haven't the foggiest what to search/ask for.

They have tip ends a bit like circular saw blades if that helps.

Re: What's this called?

Sorry for the late response...

The shoulder I make to be 1.65mm deep and the diameter to be 22mm. That's from a 750w standard smaller-sized angle grinder.

On our big-Bosch-monster (still m14) the shoulder is perhaps a little less deep, more like 1.5, and the diameter is a tad under 20mm (0.3mm less or something, it would be designed for a 20mm hole).

Hope this helped.

Re: What's this called?

with regards to the red things my best guess would be that they're some sort of oversized biscuit cutter, large 2 tipped slot cutter or similar router tool.

what dimensions are they?

Re: What's this called?

@ Ellis, excellent! Thanks for the detailed response.

@ Jonny, I think you're right, although I've never known any to be this size! Stuggling to find others.

They are 5mm wide and 155mm tip to tip.

its probably not from the food industry as they have to uses stainless for pretty much everything cos they cant have paint or rust contaminating the food

Re: What's this called?

Got another What's it called?!

Those bearings people put at the front of their robot so the chassis doesn't run on the ground, but instead on the ball? I need a couple, but can't figure out their name to search for them.

Cheers!

Re: What's this called?

Excellent, thanks.

I searched T-bots for Ball Caster and it brought up nothing (despite ball caster quite clearly being in the name of several products) stupid crappy search function.

Looks like the ones I need are out of stock. I did find these though:

Bit pricey......

I'll now search for BTUs.
