DiamondSure brand Pro-Sintered
Diamond Drill Bits are also know as Sintered Diamond Core
Drill Bits or Sintered Diamond Hole Saws. These
are professional quality, heavy-duty diamond drill bits designed
for use on ceramic tile, porcelain tile, limestone, sandstone,
marble, granite, quartz and other stone, plus bricks, masonry,
concrete block, and concrete. Water must be used for lubrication.
Sintered diamond drill bits are
not very effective for glass type materials or softer stone materials
such as slate and are not recommended for use on glass or
slate. Bonded diamond bits are much more effective
for those types of materials. See DiamondSure
Bonded Diamond Drill Bits |
|
Sintered diamond drill bits have
the diamonds embedded into the metal of the drill bit tip rather
than merely "bonded" to the tip as with bonded diamond
drill bits. As the tip wears down on a sintered diamond
drill bit, new diamonds come to the surface.
Sintered diamond drill bits are
heavy-duty bits designed for long life. Generally, sintered
bits will have a long life of 20 to 30 or more times the life
of a bonded diamond drill bit, if used properly. The heavy-duty
design provides long life when drilling in very hard materials
such as porcelain tile, granite and hard stones.
There are some disadvantages.
Sintered bits are more expensive than bonded diamond bits and
the thick heavy-duty tip causes them to drill more slowly than
thin-wall bonded diamond drill bits. However, for highly
repetitive drilling in hard mateirals, the higher cost of the
Sintered Diamond Drill Bits is well worth it because of the much
longer drill bit life. Sintered bits are also necessary
for drilling beyond about 1/2" deep as the heavy-duty design
can withstand the severe heat of deeper drilling in hard materials.
Diamond drill bits are easy to
use, but many drilling techniques are different from standard
drilling. To assist our customers, basic Instructions are presented below and we have also
compiled a detailed Drilling Tips &
Techniques section. |

Raise the drill bit up slightly
every 30-40 sec,
to allow water to penetrate to the drilling tip. |
|
|
Proper drilling speed, pressure
and lubrication are necessary to keep the bit from over heating
when drilling in very hard materials. |

|
Do not use with a hammer impact
drill. |
|
Note: |
Pro-Sintered Diamond drill Bits
are 'hollow' drill bits. They are sometimes called a 'core
drill' or 'hole saw' style drill bit. However, the two
smallest sizes - 1/8", and 3/16" are actually 'solid'
tip drill bits since their very small size does not allow for
a center hole. |

Pro-Sintered
Drill Bits - Water Lubrication
Water must be used for lubrication.
There are many ways to lubricate the drilling, as explained in
our Drilling
Tips & Techniques page.
It is important to "pump"
the drill every 30-40 seconds, to allow water to seep to the
drilling tip area. Merely raise the drill bit slightly
to allow water to flow to the tip and keep the tip from running
dry. This simple technique helps keep the drill bit from
overheating, extends the bit life considerably and helps avoid
causing "heat fractures" in the work material.
Simple lubrication methods include
drilling under water in a cake pan or tub, using a small clay
"dam" around the drill hole area or even using a spray
bottle to spray water directly into the drill slot. These
simple lubrication methods are very effective when used properly
and they work well for most drilling applications.
Another effective lubrication
method and the one used by many professionals, is to use a Water
Swivel, also know as a Water Feed System.
All DiamondSure Pro-Sintered
Drill Bits have a shaft size of 10mm. Our water swivel
section includes the DX-902 Swivel with a 10mm Collet, designed
for use with drill bits that have 10mm shafts, such as the DiamondSure
Pro-Sintered bits. See: Water Swivel Devices
IMPORTANT
Diamond drill bits require
use of proper lubrication,
correct drill speed and proper pressure.
Drilling methods and techniques can vary significantly
depending upon the specific material being drilled.

Starting a Hole
Saw / Core Drill and
Using A Center Pilot Starter Bit
Starting a hollow core drill
/ hole saw style drill bit can sometimes be difficult.
Our Drilling
Tips & Techniques section discusses the various starting
methods.
Method 1: To start drilling, you can usually
hold the tip in place with your fingers while running the drill
at a very slow speed. Once the bit has created a slight
'groove', the drill bit will remain stationary on it's own.
Method 2: For smaller drill bits, you can
also hold the drill at a 60 degree angle while running the drill
at a very slow speed. As the drill bit begins to drill,
slowly tilt the drill bit up to vertical. Once the bit
has created a slight 'groove', the bit will remain positioned.
Method 3: A template can be made by drilling
a pilot hole, the size of the diamond drill bit, in a piece of
soft wood or plastic. Hold the template in place over your
drilling area and use the 'pilot hole' to hold the drill bit
in place when beginning to drill. You can also use a "V"
on the edge of a starting template to help hold many sizes of
core drill bits.

It is very important to use proper
drilling techniques to keep a diamond drill bit from over heating
and to avoid causing "heat fractures" in the material
being drilled. Proper drill speed, low pressure and good
water lubrication are very important factors. |

leverage hand pressure by a factor of about 6 to 8. So
2 lbs of hand pressure on the drill press arm can apply up to
16 lbs of pressure to the drill head. |
