Multitool Chucks- Lidl Parkside

[Brian Reay]

I have several Dremel 'clones' and have replaced the collets with small
chucks off Ebay on 2 of them without any issue- they seem to be the same
size as the Dremel shank (or quill, if that is appropriate for a hand
held drill) and therefore the most common. (8mm dia from memory but
certainly significantly larger than the other common size, at this scale.)

I bought a third, rechargeable, one from Lidl recently which has a
smaller diameter shank- after measuring it, I took it to be the other
common size of 7mm x 0,75. However, after some supplier issues, when one
finally arrived this morning, it is a 'gnats' too small to fit.


There only seem to be two sizes- to fit 8mm and 7mm shanks (or quills),
with the same thread pitch (0.75), so I don't think it is measurement
error.

Has anyone successfully replaced their collet(s) with a chuck on the
Lidl Parkside (especially the rechargeable) multitool, please, and can
advise the size they used.

TIA

Brian

(Why a third one? for a portable took kit.)

While not the Lidl kit my neighbour had the drill chuck on his genuine
Dremel jam solid so he removed it and bought a replacement off ebay
which didn't fit. I had read that some of the Dremel chucks are 9/32 x
40 TPI and mentioned it to him so he tapped the new chuck out with a
9/32 x 40 TPI Model Engineer thread tap and now it fits perfectly on his
Dremel. He said it tapped easily as it wasn't hardened. I expect 9/32 x
40 could be confused with a 7mm thread as it's 7.14mm x .63mm pitch.

Interesting, thank you.

While I'm certainly not disputing your comment- isn't is odd a European
item, probably made in the Far East, uses that thread size? Are such
this things common?

I don't know how long Dremel have been going, but Blighty only went
metric in 1965. So British stuff which began before then was all
originally imperial.

Quite often things just haven't changed, eg Myfords etc are largely
imperial. If there is an installed user base out there the temptation to
just keep using the same manufacturing tools must be considerable.

A lot of electrical stuff changed about then too, becoming metric, but
you will still find imperial niche stuff, eg lamp holder threads, often
but by no means always made by the same company or it's successors since
pre-1965.

Ooops, Dremel is US not UK. But it is a standard which is widely used,
like BSP threads are widely used on Euro, US, Japanese and Chinese air
hoses even when the actual end connectors are not BSP.

I think the US are largely still using NPT for their pipe fittings while
the ISO pipe thread is based on BSP just metricated. NPT and BSP are
close but not compatible although a gas installer I've spoken to said
the smaller sizes IIRC 1/2" and smaller are usable with suitable
sealants if you have to mix standards.

The UK hasn't always made things to inch sizes, a guy I know was looking
at a Scammell gearbox designed around 1935 and while the main dimensions
were inch the bearings were metric. He tracked down the designer who was
still alive at the time and asked him why the use of metric bearings in
a inch designed gearbox and he was told price. Apparently as rolling
element bearing were developed in  Europe they were always more common
in metric dimensions and so cheaper.

Yes in general, and so even for air hoses, but: experiment, I put "air
hose npt" into US ebay and got 5K items, while "air hose bsp" gave 2.5k
items.

I don't know why, but "international" air hoses often have BSP ends.
They may well have some other fitting on top of the BSP one, but the end
of the hose often has BSP fittings.

It's an unofficial standard, happens to be British Imperial. And, as you
say, the most common size, 1/4 BSP, mates with 1/4 NPT if you use a bit
of teflon tape (which you pretty much have to use anyway).

...

AFAIK that's true though metric and BSPT do appear. To add to the
confusion the NPT standard was previously Briggs Standard Pipe
Threads, and you use R, from the German Rohr (=pipe).
