Need a big drill the only thing what worries me is how much blow through from either inside or outside
Yes, I would turn the hammer action off for the last few inch. Nothing worse than seeing bricks all shattered outside.
I have the big Hilti rotary hammer with safety cut out if bits jam.
So it should be easy for it

I used to use a makita sds max with tct core bits. It used to fly through but you had to drill through from either side as the blow out was huge.
I can remember drilling straight through from an upstairs flat and my mate was working downstairs outside just below where I was working and he had 4 bricks fall down just to the side of him. He had a few choice words for me but still asked to borrow my drill.
Now if it is too hard for a diamond bit the hammer and chisel come out (or kanga for granite)

The pc850 diamond cores don't work with an SDS drill, they are for use with core drills that have a SOFT hammer action like the Milwaukee or the latest Marcrist (DDM1). An SDS drill has far too much impact for a diamond core drill.

No then, it would ruin the diamond pieces as the stuff that holds them in is soft
they do sell diamond cores for hammer action and ive not seen anything that says it has to be a certain drill

diamond cores need high revs, sds are too slow hence why they use tct cores, shouldnt really intermix the two, scare over my eye is a result of sds and diamond core cock up!!

I use a 400mm drill bit in my core drill and pilot with a 10mm first, not had one move yet that that wasnt more than 5mm
I spoke to Marcrist yesterday and the confirmed that the PC850 cores should NOT be used with the hammer action of an SDS drill, they are designed for use with a core drill and soft hammer eg the DDM1.
"PC850 Dry Diamond percussion cores will work on most manufacturers’ percussion drilling machines, and have been launched in conjunction with the new Marcrist DDM1 compact lightweight diamond drilling machine."

never believe the **** behind the counter (apart from Ray, who knows more than most in front) slow speed, poor clutch and high torque equals broken wrists, split foreheads or dislocated thumbs, only speaking from experience of one, seen the others and talked to manufacturers as to the reason!
or you could refer back to posts that dear old Tamz was included in, where he spouted forth on his years of experience on this matter amongst the other many topics.

Spoke to the rep later on today, they've had one on test for twelve months in the field with no problems.
If it breaks I'll just return it, they won't know it's been on an sds.
