Hammer drill keeps slipping into hammer mode

a) is usually coloured black and comes on a roll while (b) usually comes in a blue can.

In this case the answer appears to be (a)

I had a B&D drill which did that - but the speed change. Wedged the 'button' in place with a matchstick under it. Which held it in the one position.

My 13mm Bosch has a similar problem. *Hammer* action is fine. *Drill* only gives light hammer action which wrecks drill bits.

I think I caused the problem by using a reduced shank 25mm carbide tipped bit. Plenty of drill only tools in the workshop so I haven't tried a repair.

Given the price I'd be inclined to suggest a black bin bag, but if you do want to keep it for drilling only, you could perhaps push it in and secure it by filling the gap with araldite (or perhaps decorators filler, silicone, no more nails from a gun).

For quickness/cheapness I would just stick a bit of gaffa tape over it, maybe with a small piece of wood to jam it in position.

Superglue? :-)

I'm proud of you, you truly have joined the group :-)

Btw, I concur.

A bit terminal that one. what about a bit of spring steel secured by a self tapping screw which can be swivelled to block the bit of the square hole where the button moves to. Brian

I could actually do that, since I have another, heavier drill that also has hammer action. Meanwhile I took Dave Plowman's advice and jammed in a sharpened-off matchstick, which stayed in for all the holes I needed to drill.

That's not a bad idea! I'll have to see whether the plastic body is thick enough to take a screw in that region.

I tried tape already, but it slips off too easily.

Permanent!

I DO want the hammer action sometimes. Although as I've said elsewhere, I have another, heavier drill I could use. Trouble is, that drill weighs a ton, being 40 years old, German, made of aluminium, not plastic. I bought it while working in Germany in the 1970s.

Mine worked for years like that. And was easily removed/replaced to change gear.

Unlike glue or whatever.
