Which tool and cutter grinder

Hi,

I don’t post much on here. Mostly just browse through the goldmine of information posted by forum members.

I’m possibly interested in a tool and cutter grinder to sharpen drill bits and maybe end mills etc. I don’t really want a project to build like a worden of quorn, so was looking at maybe a deckel clone. There are two different types on the Warco website. Do any members on here have one of these units or could perhaps explain what the differences are between them? Also the pros and cons of each?

One of the universal grinders from Warco comes in two versions. 5C and R8. My mill is R8 so I could use my mill collets. Would this be a good idea with the grinding dust? The 5c collet version goes up to 28 mm. The R8 one goes up to 20mm. Would it be worth getting the 5C version at the increased cost of another set of collects just for the extra capacity?

The other universal grinder uses unnamed type of collets which only list 4, 6, 8, 10, 12mm. I’m guessing this might be the deckel type collets. Warco don’t list any additional collets on their website. Does anyone know if this machine is limited to 12mm?

Any thoughts of personal experiences with either machine welcome.

Many thanks,

Darren

Hi Darren

I have an Alexander single lip cutter grinder which I use to sharpen drills using the 4 facet method. This machine is a Deckel clone and uses the "Deckel" type collets. I have been able to get collets from ebay sellers, the maximum available seems to be 5/8". The od of the collet shank is 20 mm so the wall thickness is about 2mm for that size. These collets are sometimes referred to as "U2" collets. Finally these collets have a buttress thread for the closing nut. A bit of an overkill perhaps as vee thread would surely suffice?

Use the collets you have, R8. They're cheap enough if they get worn due to the dust (not that I think they would). It's highly unlikely that you'd be sharpening a cutter larger than would fit in an R8 collet isn't it, so is it really worth the expense of another collet system?

But really my suggestion is a project, not a Quorn or Worden but the Acute. Very quick to build.

I quite fancy making one of the EE Acute devices but the kit has a £48 postage price tag. I'm very tempted to get the electronic drawing set and give it a go though...

IIRC when I bought mine his local agent (see his website) was importing them in batches and dispatching in the UK.

Thanks John. I hadn't spotted that! I've sent an email to Tania to see if she has stock and to check the costs.

I enjoyed your build posts by the way!

Thanks Henry, it was fun to build.

Just had a quote from EE's UK distributor - its £16 dearer than bringing it over from Australia! I think I need to check this one a bit more...

That's probably to cover transport costs and import duties, which you'll have to pay if purchasing from Aus.

Import duties maybe but the transport cost is £48 which is included in the comparison cost Rodger. As I said a bit of an investigation required both for that and comparing the material cost if I go down the drawing download route.
