Hey! Welcome back to Gear up With Gregg's. My name's Lee and I work on the order desk
here at Gregg Distributors. Today, were going to focus on the nitty gritty, hard work that
goes into masonry hole cutting and how Norton makes it a whole lot easier.
Concrete, brick, limestone, and other hard building materials can wreak havoc on your
tools. That's why Norton designed a diamond core bit that's perfect for drilling holes
in these sturdy materials. These bits have large, laser-welded segments that are made
to hold up to even the toughest of jobs, which is why they're typically used for masonry
projects and construction.
The type of tool you use largely depends on the size of hole you're drilling. If you're
cutting a hole between two and four inches in brick or other soft material, a hand-held
core drill is a portable, light-weight solution. However, if you've got a bigger task at hand,
or if you're drilling in harder material such as concrete, you'll need to look into a core
drilling rig.
Hand-held core drills, like the HHDET 1800 are compact, allowing for easier handling
and ideal results in confined spaces. This core drill features a Smart Electronics motor
from Cardi, which means there will be no over-heating of electrical components in this tool. With
water attachments and a rugged carrying case, the 1800 core drill is the perfect tool for
moving from task to task.
But when you're taking on a big job, the hand-held drill might not cut it. That's when you need
to turn to the DR620 core drill rig. While this tool isn't as ideal in tight spaces,
its versatility is where it really shines. The pivoting column makes drilling on a sloping
surface a breeze, while the ceiling jack and vacuum pump mean that no matter where you
need to drill, your unit is stabilized. With the capability to handle bits from 2 to 10
inches, and a wheel attachment for easy transport, the DR620 can handle any job you throw at it.
Now, there are a few things you want to watch out for when using a core bit or hole cutting tool.
First, it's important to know that just like most heavy-duty diamond saw blades, most core
bits need to be used wet. This means that you need to keep a constant supply of water
on hand to make sure that the hole you're cutting is being flushed of abrasive materials.
This will create a slurry, a mixture of dust and water. Using water not only reduces dust
and lubricates, but it also helps to cool down the tool that's working overtime. However,
don't use too much water when drilling! Too much water will wash away the dust before
it is able to become a slurry. While this might not sound like a bad thing, this abrasive
slurry is what's helping to expose new diamonds in your core bit.
And, since you're likely using water to cool the bit, you'll want to make sure that you're
also using a grounded electrical outlet with the appropriate voltage and GFCI protection.
After all, electricity and water don't exactly mix.
If you are drilling a dry hole, you will want to be sure to pull back every so often to
keep the dust from building up in your hole. If you don't, this might lead to something
called binding. Binding is when the core bit gets stuck in the material you're trying to
drill. This sudden stop can lead to a nasty shock when the drill you're using keeps going
but the core bit stays still. Very often, this results in operator injury.
Then, you want to make sure that the bit is slowly lowered into the cut and that the entire
circumference of the core bit penetrates the drilling surface before adding any additional
pressure. Once the bit has started the hole, use steady pressure on the bit while drilling,
but don't force the bit into the material! And don't stop the flow of water! Otherwise,
the bit might overheat and you'll end up damaging the bit or workpiece.
These core bits can handle some tough jobs and are able to drill through steel-reinforced
concrete, hard bricks, terrazzo, and many more materials. But if you find that the drilling
rate suddenly decreases, you've probably got some dull segments on your hands. This means
you need to replace the bit.
And if you need to replace your core bit, don't worry, we've got a great selection,
ranging from 1 inch to 14 inches in size. Or, if you're just getting started and aren't
sure what size you need, be sure to give us a call, and one of our friendly customer service
staff would be more than happy to help you out.
