Checked with magnet? First thing I did. Clink. I think my collet is better finished although it is hard to tell with photos. I will try to remember to take a picture of mine tomorrow. Modifying the collet. Lucky I have the dremel collets but will have to check how well they work. I have some diamond burrs but they are 1/8 inch shaft.

A picture of the two collets. This was one of my first shots in anger with my new SLR. It is a lot more complex to use than the old Film ones languishing in the cupboard. Take me a while to learn it fully.

I take it the one on the left is from the air grinder ?
The one on the right looks to have a longer tapered section on the screw cap end ?
Angles look a bit different.
How well does the Dremel one fit ?

Steamwhisperer!!!!
This is my receipt - show it to Bunnings to match price!!
regards Ned
Note: these were reduced by varying amount to get to this price. Ticket was orange clearance - Original price $44.00 - 33.00 - 24.00 when I bought it. same in other Bunnings in Newcastle/Maitand/Lake Macquarie stores. - I think that they are changing suppliers and shifting old stock.

Thanks Rob for the heads up. I had this little unit delivered recently. I'm sure I will find many uses for it.
I already have a couple of Dremels, but this air grinder feels so much better in the hand and more powerful.
I have only started it up and had a short play with it. I normally use it to "high flow" throttle bodies. With the slim body it will make that job easier.
Cheers,
Bill

Should be good for that sort of work.
It seems that everyone thinks "Dremel" for this sort of work, and these air powered units slip under the radar.
Probably a marketing thing, and not everyone has an air compressor.
The fact that these can't be burnt out and are dead easy to mount on a tool post make them a winner IMHO.

Grinder on eBay
This old school item may be of interest to someone looking for a pencil type micro grinder. So far it's cheap.

After a fruitless search at Bunnings and being a cheap skate , I bought a budget grinder from "Melbourne Tools" - Grinding Stones AIR DIE Grinder Wrenches Tool Combi SET ALL Grinding KIT | eBay
I notice that the CTC 4 bearing model comes with both a 2 and a 3mm collet. I imagine the Melbourne special is accompanied by a lone 3mm. Now here's the thing, I have a Grobet USA catalogue, 24 pages of which are devoted to jeweller's burs BUT they are 2.4 mm (3/32") shanked. Quality German and Swiss burs are available on Ebay but again smaller shanked - Setting Burs FIG413 Jewelers Burs Stone Setting Jewelry BUR SET 024 050 12 Piece | eBay
Has anyone had a go at making a miniscule collet for one of these grinders?

Bob, my CTC pencil grinder set came with a spare collet in size 3/32", as well as the 3 mm collet fitted in the unit.
They look pretty easy to make - it's a very simple design.
Also slightly OT I was in Bunnings at Mile End and I see they have the next size up die grinder (with lever throttle control) with a set of grindstones for $20.
This is the same price I got one from CheapAuto a while back.
They are quite a good unit for the money. I use it for cutting with a thin friction disc. They use a lot of air though.
Worth a look.
Rob
