Electroplate
Bonded Diamond Core Drill Bits
DiamondSure brand Diamond Drill
Bits, are also know as Diamond Core Drill Bits, Diamond Hole
Saws or Bonded Diamond Drill Bits. They are
used to drill glass, ceramics, porcelain, ceramic tile, porcelain
tile, limestone, slate, marble, granite, light stone, and fiberglass.
Water is required for lubrication when drilling.
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. |
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 bit and a smaller "plug"
or "core" which comes from the center. The Diamond
Drill Bits are available in sizes from 5/64" to 5-1/2"
(outside diameter). The metric manufactured size of each
bit is also shown below (mm), along with the exact inch measurement
of each of the bits. |

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 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 drill bits 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 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 used primarily on glass, stained
glass, china plates or fiberglass.
These solid point bits are not
designed for drilling 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 solid tip drill
bits drill out the complete hole, they also drill more slowly
than the hollow core style 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. Hollow core style drill bits are recommended
for drilling in these very hard materials and are available from
1/8" to 4" in the section, above. See also Diamond Core Drill Bits and How
to Use Diamond Drill Bits.
