I'm going to get slated but....

[polo1]

I've managed to get a 450mm SDS (10) masonry bit jammed solid, going up at an angle above a door frame. I think it has got stuck at some reinforcing in a lintel. I have about 50mm still showing, but can't get the bl**dy thing to move. It's in a domestic property and the lady of the house ain't best pleased.
Any suggestions as to how I might retrieve the offending item ( and yes, I feel like a right t*t!)??????

at least he'll have a clean bit.

I was drilling down through my foundations for a water pipe and got TWO 1m drill bits stuck down the hole under the cupboard, I was, eventually, after about a days drilling, able to get them out by drilling beside the bit with a smaller bit (that was how I got the second one stuck) and it is amazing how much clearance you need to get the bit out. Oh yes and spinning a masonry drill bit beside another bit, one tends to catch in the flutes, two tends to wear out the flutes.

I did the above about 20 years ago in an electrical cupboard in a large building got both drill bits stuck and there still there

I managed to get an armed chasing bit stuck tight down the back of some skirting last week tried everything to get it out! Hammer grips etc. ended up putting a 16mm bit down the side of it with the SDS to give it room to wiggle out.

I got one out on a similar situation by lifting a board in the house, so we could turn then hit the end of the bit while someone turned it the same way outside with grips, took a while , the actual problem was the drill had gone up the edge of lintel so it was effectively screwed in until the lad jammed it solid

Been there got the T-shirt and found the best course of action without destroying everything is some large pipe wrenches, a no'10 sds bit has a excellent shaped base to purchase on with a wrench now depending what has jammed it it will either work free or snap at its weakest point
P.S. hope your not drilling through a lintel especially a pre-stessed one... seen them explode before on a demolition site when the digger damaged it.

Off topic but related to Darkwoods post,
I used to build and install moulds for prestressed concrete T beams mostly these moulds were 75m long and upto 5m wide each wire had 1 1/2 tonnes of pressure placed on them via hydraulic ram each beam usually had 5 wires , the wires passed through a 3" steel plate at each end and were held by a small locking device gripping the wire,
when these failed the result was the captive wire lock would have roughly the same energy as a rifle round and the wall behind had perfect holes straight through engineering brick and into sandbags!

I find using grips the best method, just get them on the end and rock them back and forth both ways unitil it loosens, best to learn how to use a drill though, always pull the drill out of the hole every so often to remove dust to avoid jamming lol.

half a pound of semtex would be quicker.

Say that you need to get something from the van and drive off !!

Something you routinely carry around?

I almost had this issue a week or so ago going through an outer wall down into the porch when the cu was, lifted a flood board and pointed the drill at quite a steep angle downwards, it was a 600mm 10mm bit, sds, it was squealing like it had touched the edge of metal.

I managed to just get enough back up to connect to the drill, to get it out.
