Diamond Core Drill

[Phil]

I see Screwfix have some of the Sparkys in stock now, £139 for 1100W or £179 for 1250W. Can't help thinking the 850W Makita is more powerful though as I've used both.

I use a Makita 2450 standard sds hammer drill not on hammer with a core of up to 127mm through brick. The clutch slips sometimes but at least you dont loose your arm. I have had the drill for 3 years and use mexco core. If the core sticks alot use water from a squeezy bottle to lubricate.

I have used the makita extensively for severla years, they are brilliant. Had two fail on me in probably 5 years, possibly usng it 4 or 5 times a week on average. One the clutch went, the other started spraying an oily substance out of the vents all over the place. was not particuarly that day. Other than that, faultless.

do u think its a bit of a risk tamz ??? it could be gubbed eh ? what is this brand new with warranty? about £100 quid more ? ??? is this one of the best around ???

 

[mcniven]

tamz, iv spoke to the guy from the link u gave me, £140 is that worth it aye ????

They have a lifetime warranty. I have had mine for about 3 years and have severely abused it to the point where it is so hot i can't touch the body. It still does the job perfectly. 90% of the work i do is in tenements drilling through solid stone walls up to 42" thick (fireplace cupboard out).
Even if it was gubbed which is highly unlikely it would still be better than most so called core drills. If you are doing a lot of heating time is money. Use an inferior core machine and i would have the hole cored the boiler hung and flue done before you were through.
They are the best machines available for the money and better than many more expensive ones. Before i bought it i was going through a core gun every 3 - 4 months and i have tried just about every make out there. I was about to spash out £800 on a hilti when this was recommended to me by a diamond driller. It really is a good machine and has been worth every penny. If mine died tomorrow i would buy another (well maybe the DDM3).

Buying 2nd hand is always a risk but a second hand beemer is usually better than a new vauxhall. The one on your link looks in better nick and has not been abused much (it is quite clean and not many marks on).

Can an adaptor be bought to fit a normal chuck on the DDM2?

 

[tamz]

Don't know. It is too heavy to use as a normal drill and has no hammer. It is a dedicated diamond drill.

 

[Phil]

Interesting, no hammer function?, in a way I'm glad I didn't buy one then although I was tempted. I bought the Makita in the end (hasn't arrived yet) after months of pondering which one to get. I have loads of Makita tools and so far they all been fantastic so I have no reason to buy another brand.

With a chuck I could use it for other things, like when I forget my sds drill and have to mix plaster with my cordless drill.
