good concrete below ground gets harder and stronger for at least the first 50 yrs
i have the same model of chisel, i can be rough on tools but that is impressive
that sort of concrete needs a good sds for drilling and a good, suitably sized, breaker for chipping and demolition
even more "bitey" tools are available if necessary
my least favourite brickwork to make a hole in was a chum's 1949 vintage flat in london
the gable wall where i needed to make a hole for a boiler flue was triple solid engineering brick with an air gap and very abrasive and solid composte block as an inner skin, nuke proof social housing, and they were second floor up, and the boiler was going in a smallish very solid cupboard
i never even considered making a hole in a floor but curtain rails and plumbing runs were no fun
ace building ,hard to make holes in, did it but the words would have made a pirate blush and i broke 2 drills(drills not bits)
re a new chisel, send youngster to boot sales, flea markets etc to seek out mid victorian stone mason's tools, far superior to modern stuff
it might need sharpening if it has been misused(a slightly skilled job to do it properly) but they fettle up a treat (used properly they self sharpen with use, same as a breaker chisel)
my best pair, inch bar to wedge and 3/4 inch to star 6 point were ace for tunnelling gritstone which is up there with good concrete |
