DRY CARBIDE CORING v DRY DIAMOND CORING
INTRO (NICK) Alright, I'm sure you know there are
Carbide Coring Bits and Diamond Core Bits but many of the most common questions we get
are around which core bit to use and what tools work with each.
They've both been around for years and frankly, sometimes they're a pain in the ass.
I'm Nick with Ohio Power Tool, let's talk about Carbide and Diamond Core Bits.
V/O (NICK) Typically carbide core bits go into
rotary hammer drills and diamond core bits go into specialty core drills, either hand
or rig mounted.
Most professionals have a hammer drill and not everyone has a core drill so sometimes
the application can be troublesome.
but don’t worry we’ve got some options for you we’ll talk about in a second.
(NICK) Coring is time consuming.
well, time consuming if you're not coring anything tougher than cinder block.
Of course you want a smooth core and not blow out the concrete on the other side....
Annd that's a good segway into talking carbide.
Don't get me wrong, Carbide is a great solution!
It cuts well, long lasting and an overall great accessory for simply making a hole in
concrete.
However, it’s pounding the concrete the same way your chisel pounds the concrete when
you want to remove it, when it comes to coring, there are several solutions.
(NICK) When coring into poured concrete, you'll inevitably hit rebar or steel.
This will actually chip off the carbide segments, causing a much larger headache.
If your segment pops off, now you're trying to cut through steel and carbide...
Good luck with that one buddy.
(NICK) The way around this is you core all the way to the steel or rebar, stop and switch
your bit out to a Rebar Cutter in drill only mode, knock that out, then put your carbide
bit back in and continue coring.
It works and will save your carbide core bits, great!
There is another option, Diamond Core Bits, and you don’t need to but a $1400-$2500
specialty core machine to use it.
(NICK) We carry quite a few of solutions to diamond coring, wet core, dry, threaded barrel,
etc from Diamond Products Core Bore and Dytec.
There are many advantages to each type of coring, and eventually we'll do some in depth
coverage of core drill bits.
For now, let's focus on dry coring with a diamond bit because if you are comparing to
Carbide we really are comparing to dry coring.
Unlike the carbide, Diamond bits can continue through that steel or rebar without need of
switching it out.
This is because the bits are not pounding the concrete they are technically grinding
it, so grinding metal works pretty much the same.
As you can imagine, that saves time, which is important if each hole takes 10-15 minutes
and you’ve got multiple to do.
But that isn't the only benefit with Diamond Coring, as you'll also gain quality.
Often the pounding of the hammer drill has some not great consequences on the ack of
the hole as well, it’ll blow out and you’ll have a mess.
Running utilities into someone’s finished basement this is not a great look.
With Diamond there is no pounding, since you’re grinding you'll get a nice clean core without
the risk of blowing out the back end.
(NICK) Most of our customers know this but maybe haven’t invested in a core drill yet
so make due with they hammer drill and carbide core bits.
Did you know you can still use a diamond core bit with a hammer drill now?
Yea..
It's real.
Diteq made an adapter for SDS-Plus or SDS-MAX and It works fairly well but only if your
drill has a rotate only mode.
All SDS-Plus have this mode but thats not the case with all SDS-MAX. so you'll want
to check that out first.
Of course it’s great to have a dedicated core drill but if you’re not coring everyday,
just wouldnt make sense.
OUTRO (NICK) There is nothing wrong with coring
carbide, we just want to let everyone know there are options.
Often it doesn’t matter what the back side of a hole looks like.
Either way, we're here to help!
