Core drills

[gasmanrob]

Lame why don't you invest in a bolt on unit? Then all you need to to is wind a lever in and let the drill do the work ok it's an investment but protection of yourself plus you seem to get a lot of these stone walls. Look what you've done to get baffles out of oil boilers regarding your rig...

the wall I cored on friday wouldnt have been suitable to get a rig attached imho, they are great on flat concrete on the ground but a beggar to attach to an unstable victorian wall. not sure where you coming from with oil boiler baffles?

Cores are no good for this sort of wall.


I used to dig these sort of walls out by hand in half the time. Once you've broken through the first build up, dig all the crap out with a long cold chisel and with your hands in there. Then just pop a hole through the last bit with a metre long bit and lump hammer the outside in. Jobs a goodun!

I used to fit oil boilers non stop down in Cornwall and this method worked best every time.

good in theory, but round here you'd end up with a new window if not a door! Any movement and the whole wall starts to collapse round your ears, having tried all methods, slow n steady with a core n drill is the only way I have found to work sensibly. I gave up hammering out huge rocks years ago when I first converted my place into apartments.

Thought you had a rig with a hoist for removing the plates out of Aga's due to a bad back

Good in practice as well, worked all around Devon and Cornwall, including North Devon!

Has anyone ever had the clutch replaced on a Makita 8406. Had mine about 5-6 years now and rang the local stockist last year about a service and they told me to throw it in the bin and buy a new one as it isn't worth it ???

I had the Makita 8406C core drill and it did me good service over the years I had it. Repaired it a few times but last year it gave up the ghost. I bought the Milwaukee DD2-160XE drill and it's streets ahead of the Makita. Rips through a wall in less than half the time of the Makita.

Thanks for all the replies and advice guys. It's much appreciated.

I decided to get the milwaukee drill and the Marcross ccu850 drill bits.

The drill arrived today just in time to do a few holes. 2x2 inch holes and 1x5 inch.
It all works a treat. The easiest and fastest holes I have drilled. The 5 inch one was at a 45 degree angle through a solid outside wall, made of very hard bricks, and it did it no problem at all.
I am still covered in dust though!

Vacuum duck taped to the wall next to your hole always helps but dosnt get everything

That day my vacuum was having a day off so I was down to using a broom. I tried taping that to the wall but it was not really the same :tounge_smile: I was indoors too which didn't help

Give these guys a call...

Which Hilti core drill do you use i am looking to get a second hand one. I have been using and abusing the Makita 8406 for the past 7 years and the clutch is just starting to go.
