Tools of unknown types.

As part of a lot obtained some months ago I found three set of toolings whch I have not seen before.

The chuck backplate was mounted to the 125mm chinese chuck but to put on which lathe.

The QCTP has a geometry unknown to me. Any sugestions.

The collet set is not an ER set but what type of collets. Longer than my ER32.

All are unused and in good conditions. Bought from Little Machine Shop, USA some years ago the seller said. Searched the site but could not find them.

I hope for some help as I intend put them up for sale and like to have some information in the ad.

Rest of the lot will be put into good use in my workshop.

Some more photos. Any help to identify them are apreciated.

There a lot of similar collet chucks on the market. They are definitely not ER type collet. They resemble Acura grip or TG collets but my not be compatible with either system.

The toolholders and toolpost are Siegs design, they do different sizes for different size lathes. They work moderately well but are not as good as some of the better quality QCTPs.

The backplate bore looks like 52mm, which (assuming the plug bolts are 20mm diameter on a 75mm PCD) fits the Seig C6/SC6. If the bore is 50mm it fits the Chester DB10 Super.

I think the ones shown are known as Oz collets.

Do the collets belong to what appears to be a milling chuck ? Are they metric or imperil or a mixture

The collets are all part of the box in photo 5. Metric set of 3,4,6,8,10,12,16 mm collets with milling chuck MT3? and spanner. Unused still oiled and in plastic bags.

OZ collets it is, thank you.

Yes, a Sieg design from some years ago. Little Machine Shop is selling Sieg stuff.

I have Emco and A&R QCTPs on my lathes and lot of tool holders, so I will try sell the surplus from the lot. I think they are not in sale anymore so hope to find a chap that still has and use them.
