DiamondSure brand Diamond Core
Drill Bits, also know as Diamond Hole Saws, are used to
drill glass, ceramics, porcelain, ceramic and porcelain tile,
limestone, slate, marble, granite, stone, and fiberglass.
Just add water for lubrication.
Old fashioned
Spear Point carbide bits no longer work
on
the new type of super-hard floor, counter and wall tiles.
Diamond
Drill Bits are the solution. |

Info of Core Drills
<Click

Core drill bits have a hollow
center and cut a circle in the material to create a hole. This
results in a hole the size of the drill and a smaller "plug"
or "core" which comes from the center. Diamond
core drill bits are available in sizes from 5/64" to 5-1/2"
(outside diameter). The metric manufactured size of each
diamond drill bit is also shown below (mm), along with the exact
inch measurement.
Diamond drill bits are easy to
use, however, there are many special techniques which are different
from standard steel-bit drilling. Diamond drill bit usage
can also vary depending upon the diamond drill bit type and the
specific manufacturer. To assist our customers, we have
compiled a detailed Drilling Tips & Techniques section. |

SPEED KILLS: |
Reduced drill
speeds, low drill pressure and increased use of water lubrication
will extend drill bit life considerably. |
|
|
|
.
Because diamond drill bits
are used to drill in extremely hard materials, it is very important
to use proper drill pressure to keep from overheating the drill
bit. Excessive pressure is merely converted to heat energy
and can burn up a bit very quickly.

* WARNING: |
Drill press arm leverages hand pressure by a
factor of about
6 to 8. So 2 lbs. of hand
pressure on the drill press arm will apply about 14 lbs of pressure
to the drill head. |
All diamond core drills have
shaft sizes of 3/8" or less, for use in standard drills.
For detailed drill bit size information (total length, shaft
length and bell length) - See drill size

IMPORTANT
Diamond drill bits require
the use of proper lubrication, correct
drill speed
and proper pressure. Drilling methods and techniques
vary significantly depending upon the material being
drilled.
Not for use on Concrete or with Hammer-Impact Drills,
or for depths beyond about 1/2"

Blunt
Nose Solid Diamond Drill Bits
Electroplate Bonded Solid Tip Diamond Drills
For drilling glass, stained glass, china plates
& fiberglass!
Blunt Nose Diamond Drill Bits
work with any drill - just add water for lubrication. Glastar
brand Diamond Drill Bits are much easier and safer to use than
old-fashioned spear point steel drills and don't chip the work
material. Blunt Nose Diamond Drill Bits are basically glass
drill bits for use primarily to drill glass, stained glass, china
plates or fiberglass. The solid point bits are not designed
for drilling ceramic or porcelain tile, floor tile, limestone,
slate, marble, granite or other stones. Glastar Blunt Nose
Drill Bits are designed to be used at high speeds up to 10,000
rpm.
Since Blunt Nose bits have a
solid rounded tip, they are slightly easier to start when drilling
on a curved surface, such as a bottle, when compared to using
a Core drill bit, above. However, since Blunt Nose bits
drill out the complete hole, they also drill more slowly than
the Core bits and they are generally not used on the super hard
abrasive materials such as ceramic or porcelain tile, floor tile,
limestone, slate, marble, granite or other stones. Blunt
nose bits are available in three sizes, 1/8", 1/4"
and 3/8". Core drill bits are resommended for drilling
in these materials ans are available from 1/8" to 4"
in the section, above. See also Diamond
Core Drill Bits and How to Use Diamond
Drill Bits.
