If it is the pull-back locking system to hold in the chisel, or drill bit, then the locking- clutch mechanism is worn and needs replaced

How do I get a drill bit out of the shaft of my rotary hammer drill snapped in it. No bit showing.


unmount the locking rings pins or ball of the toolholder while chisel is inside its possible make the parts short time hot with a burner not to long (where safety glasses ) and leather apron in case of splinters that can come off . spray some wd 40 on the hot part before use a bench vise to set the chisel in with machine on it and the beveled edge of the benchhammer on the front of the tool holder and with a second hammer beat the other site on the benchhammer to work slowly the machine will come off from the chisel. in most cases the drill guide has been worn out from the chuck in case off a cheap rotary hammer it make no sense to do it all. because it has had it working hours on it.

Can this drill be used as a hammer only for chipping?


if it is an elcheapo drill then it cannot be used for hammering only
it can only be used as a drill or a hammer drill
what you need is an expensive hammer drill ( Ramset or HILTI for masonry work that can accommodate a chisel tool and be used for chipping
however if you want to just chip there are cheap air driven chisels , that will do the job
find a good tool shop and there will be a range of tools that will do what you want

How to chisel


The Bosch 1199VSR Hammer Drill is capable of drilling or hammer drilling at two different speeds but can not hammer or chisel only. To do that you need a demolition hammer or roto/demo hammer tool.

Hi, I hope both of my problems are related. The chisel is "stuck" and won't release. Also, the unit does not "hammer". The motor runs and when I select drill the unit spins. I...


you need to get that chisel out. If it was hammering with it before the end of the chisel might have broken and not coming into contact with the striker, if it did not then the end of the chisel might be damaged not allowing it to seat fully, either way get the chisel out and put in a regular bit and it will probably work.

Do all sds drills have chisel function?


The SDS designation relates more to the type of chuck on the tool for the bits than to the tool/drill itself. There are both chisels and drill bits with SDS-Plus and SDS-Max shanks, SDS-Max being the the larger of the two. As far as the tools go: Demolition hammers will only hammer and can only use pointed chisels, scaling chisels, scrapers, etc, not anything like a drill bit that requires spinning to work. Rotary hammers can hammer and rotate the bits. Rotary hammers have a selector switch with two or three positions; one for hammer only for the above demolition bits, one for rotary hammer for use with carbite tipped drill bits, and some have a position for rotation only. The rotary hammer is a more versitile tool but more expensive because of extra workings inside.

My hilti te-75 drills but is not hammering or will not go into chisel mode whay coud be the problem with it


Have seen this problem with some 'none' HILTI bits which do not fit correctly into the SDS chuck.
Tends to be with larger drill bits which have a wider shank than the SDS connector, the wider shank hits the end of the drill nose which stops the end of the drill bit contacting with the internal hammer.
Solution is to purchase original bits from Hilti. If you have OEM bits and chisel it will be another problem. Hope this helps.

I have a HILTI TE905 breaker and something is seems wrong with the chuck or the chilsal as it keeps falling out of the end and not gripping it. Is it possible to take the chuck apart to see if I can spot...


I have just dismantled my own TE 905 to see why it was dropping the chisels and have found the following:-

1. The chisel is worn and has almost become too small for the chuck. (mesure the thickness of the chisel at both ends of the hexagonal shaft and see the difference)

2. The chuck is worn and will probably need to be replaced.
I phoned Hilti today and was quoted £100 for ONE PART OF THE CHUCK!!!

a. The chuck as a whole can easily be removed by undoing the four torx screws that hold the chuck on to the main body.

b. The chuck can be dismantled by removing the retaining ring that holds the metal outer case in place at the front of the chuck. This is very fiddly and requires some engineering skill, the use of pointed instruments could easily result in injury.

The third fix is the one I am going to use to 'patch up' my old breaker. This involves welding some small amounts of dissimilar weld onto the points of the hexagonal section at the rear of the chisel then grinding them to near enough the original size of the un-damaged section of the chisel.
This will very crudely stop the chisel from passing the ball bearings inside the chuck. PLEASE NOTE THAT ANY HEAT APPLIED TO THE CHISEL WILL CAUSE STRESS AND POSSIBLE FAILURE OF THE CHISEL. ANY MODIFICATIONS OF THIS NATURE COULD RESULT IN INJURY TO PERSONS WORKING AROUND YOU AND ARE NOT RECOMMENDED IF YOU ARE WORKING AT HEIGHT OR WITH PEOPLE BELOW YOU. This is a fix that should only be attempted by competent engineers for use on a DIY or small job basis. Hope this helps.

Stuck chisel


if you have access to a vise I would lock the chisel in it and pull on the release collar and then take a dead blow hammer and "tap" on the drill to try and pull it away from the chisel.
