Diamond core drilling is a common technique in the mining industry for extracting core samples. It is ideal for geotechnical work in semi-consolidated/cemented rock to hard rock environments. Downward pressure and high rotation rates advance drill bits that are faced with diamond impregnated steel.
What is a diamond core drill?
Diamond Drilling is a form of core drilling which uses a rotary drill with a diamond drill bit attached in order to create precisely measured holes. As diamond is the hardest naturally occurring material in the world, it is ideal for creating openings in a range of materials including concrete, metal and glass.
What are diamond core bits used for?
A diamond drill bit is a helpful tool when it comes to making holes in hard non-wood surfaces such as ceramic, porcelain, glass, stone, marble and granite. Diamond drill bits get their extra cutting power from little pieces of diamond powder embedded in them.
How long do diamond core bits last?
Varying with application, an average electroplated diamond core drill/bit will last you 80 to 120 holes. Whereas a conventional metal bond (sintered) diamond drill should last you about 1,200 holes. And a diamond drill with SMART CUT™ technology will last more than 2,000 holes.
Will a diamond core bit cut rebar?
Diamond core drilling is a high-speed, high-production method of drilling in concrete, stone, asphalt or masonry structures. … Core drills cut easily through rebar, allowing the holes to be placed wherever it is most suitable.

Is Diamond drill bits real diamond?
The makeup of these drill bits consists of real diamond powder, pressed onto the steel using this very high pressure. Diamond, being the hardest substance, still maintains its heavy cutting power after the process, and the drill bits come in different sizes.
Are diamond drill bits any good?
They are the best drill bits for rock, DIY or craft projects and for the professional tradesman. Diamond drills for tiles is a must and will drill holes far easier and with a smoother cut than any other tile drill bits.
Why can diamond be used as drill bits?
Heavy-duty drill bits – such as those used in the oil exploration industry to drill through rocks – are made with diamonds so that they stay sharp for longer. Diamond is insoluble in water. It does not conduct electricity.
How Can I drill a hole in glass without breaking it?
To prevent glass damage, you must drill a starter hole at the marked point.
- Place the point of the drill at the center of the marked point on the glass.
- Pour a few drops of lubricating oil on the area around the drill tip and glass.
- Beginning at low speed with medium pressure, drill a small starter hole into the glass.
How do you get a core bit unstuck?
To Remove a Stuck Bit
Then place two hex nuts on the rod and lock them against one another so that they in turn lock themselves to the rod. Turn the nuts with a wrench which will turn the rod which will in turn push against the concrete core, pulling the bit from the hole without damaging it.
How deep can a core drill go?
Core drilling can make holes from three-fourths of an inch, up to about six feet in diameter. Depths can reach sixty feet.
Is it OK to drill through rebar?
Drilling through concrete that has reinforcing bars in it doesn’t mean you will hit the rebar so in one sense, any hammer drill or rotary hammer with a bit designed for concrete will do the job, unless you actually hit a rebar.
