My SDS (Lucky Screwfix Hedgehog) has started making a loud chattering noise, there seems to be a lot of play on the bits sliding in and out of the SDS chuck, and it's not chiselling as effectively as it did.

Has it passed over the rainbow bridge to the great toolshed in the sky?

Has it been greased?

Not since it left the Lucky Hedgehog factory in July 2013. I don't remember any instructions about greasing.

I suppose for £50 and 7 years it doesn't owe me anything.

Wasn't there a plastic tub of grease in the case/box?

Dip your bit a few times & try it before you bin it?

My green Bosch rattles a bit if there is little or no pressure on the
bit and the action is not very effecctive. Comes a point as you
increase pressure that it suddenly "tightens up" and works as it
should.

No.

Will do if I can find some grease. It goes in okay, it just doesn't seem to be gripped by the SDS mechanism in the usual way. It's captive and locks for turning, but rattly.

Might be worth flushing and working "chuck" with WD40 or similar first.
And/or blowing out with an air line if you have one.

If it's never been greased there may be a lot of grit and dust in there.
They do need to be lubricated IMHO.

Graphite lubricant?

The outer part of the *chuck* mechanism went astray on mine, ( kango,
but the tool retention must be the same) revealing a captive steel ball
retained by a spring loaded sleeve.

I haven't bothered to get spares and occasionally the ball drops out.

All sds drills work that way. The action doesn't really start working
until there is slight pressure on the bit. The drill mechanism hits the
bit forward and you pushing the bit into the work piece pushes the bit
backwards to be hit again by the drill mechanism. If not drilling into
anything the mechanism pushes the bit as far forward as it can and then
retracts back but nothing is pushing the bit back into the chuck
therefore on the next cycle the mechanism is not hitting the back of the
bit (or is just lightly tapping the fully extended bit).

I've often found situations (like nibbling something away) where a
return spring would be useful. I try to use my hand but an external
clip-on sprinq would better - never thought of it before but it should
be easy to knock-up something suitable.

Grease seems to be the norm in spite of the fact that it will collect
abrasive dust (although also it provides something of a seal). Graphite
is not the best product for high loads, moly disulphide is better.

Not having any of those, I've tried a squirt of beard oil. It smells nice :-0

It's a bit less rattly, but as it suddenly started rattling, I think something inside is broken. Nothing's fallen out though.

It's a shame as Screwfies have stopped that model and all the others are bigger/heavier/pricier. 3.5kg was just right for what I need it for.

CV boot grease. Most garages have loads of spare sachets.
