Core Drilling

[andf380]

Been using a sparky core drill mainly use it to core holes for the flue only it seems to grab alot and nearly breaks my wrist before i purchased the drill i used a ordinary dewalt hammer drill with a good clutch used that for about 3 years before it finally gave up just thinking of going back to a ordinary dewalt D25213K sds plus hammer drill Just wondered what your thoughts were on core drills

 

[Billy Bob Bob]

sounds like it has no clutch i use the makita core drill

 

[andf380]

Do you have any problem with the makita drill does that ever snatch

 

[Billy Bob Bob]

it does but the clutch kicks in

I have always bought cheap drills for my flue cord drill,the last I bought was about 4 years ago for about £50,jcb drill ,see £90 now,it has had so much hammer (pardon the pun) and still going strong

I have had my Makita drill for years and its paid for itself no end, imho best
to use the drill designed for the job, I remember nearly being thrown off
a ladder core drilling and not using a proper drill.

Thanks for your reply's will probably go for the makita core drill when i bought the sparky i assumed it would have a clutch on it

 

[ratrace]

Which makita one are you using gasman?

 

[Billy Bob Bob]

the 8406 Makita Drills and Fastening / Diamond Core Drilling Machines

 

[ratrace]

Been looking at that myself. Varying reviews on it have left me a bit undecided. Does the clutch tend to kick in quite easy?

 

[Billy Bob Bob]

yes buy only if the bits worn,had min e 4 years so there are probably better ones about now

[plumbster3456]

i got makita and it is very good used to try and core with sds years ago it wrks to an extent then you have to try and core through a thick wall and the sds dont work and sticks and nearly kills you...
makita core gun has paid for itself and plus due to the clutch i wont snap my wrist,,,,

Rubbish hilti dd110 with hilt cores using hilti starter bits no need for pilot holes, bits are 500 mm long so in most cases straight through with no messing around, for deeper holes you just put on an extension. I have mine on fleet hire from hilt including the vacuum which enables dust free coring guaranteed, it costs about 45 quid a month and the cores get re-tipped worth every penny. Never have to core from outside in up ladders because of dust etc. Never seen another tool that compares. If you fleet hire it all maintenance is free and you are never without the tool. The bits are a bayonet fit as well which is dead easy.

 

[gaspastemania]

never had probs drilling flue holes , practiced many a times as an apprentice ,,,,brute force and ignorance

 

[Billy Bob Bob]

oh yes the only way

 

[GQuigley67]

i had to core alot of 4" and 2" holes for 3 toilets i installed few months ago, took me 6 hours was like a chimney sweeper after it! luckily i had ear defenders
