IDENTIFYING THE
PROBLEM |
The need to drill holes in tile, range from
mounting a grab bar or a shower door in a tiled bathroom or installing a towel
rack on a tiled kitchen wall to drilling hundreds of holes to bolt down pews on
a newly tiled church floor.
There is a common misconception that almost
any masonry drill bit can drill any tile (it just takes a little longer to
drill hard tile). This is still the advice you might get in some tile stores
and home improvement centers. But with the increasing popularity of tile, there
are now many more types of tile available, some being 30% stronger than granite
and impossible to drill with carbide or masonry bits.
Based on the
number of inquires we have received on how to drill holes in tile over the last
few years and the reports of many disappointing results with "masonry" bits, we
undertook a drilling study to evaluate the existing tools available and
determine if there was a need for a new tool specifically designed to drill all
types of tile.
After drilling thousands of holes in hundreds of
different types and makes of tile and testing every bit that was recommended to
do the job by the knowledgeable people in the field, we came to the following
conclusions which led to the development of the 'TILEBIT'.
|
CONCLUSION |
Tiles that are marked, identifying their
durability or class/PEI rating normally are difficult or impossible to drill
with masonry bits. (Tiles made for applications not requiring a high rating are
normally not labeled.)
In general, the drillability of tile decreases
as the tile's hardness, breaking strength, and abrasive resistance increases
and its water absorption rate decreases.
1. Masonry carbide insert bits, including the
spear point - "Glass & Tile" bits and "Hammer Drill" bits perform only
marginally in drilling...
A. Class/PEI III tile. B. Tile of Mohs
hardness 5. C. Tile with a Water Absorption of 5% and D. Tile with a
breaking strength of 200 lbs.
2. These masonry bits perform
unsatisfactorily in drilling...
A. Tile Class/PEI IV and above B. Tile of
a Mohs hardness 6 and above C. Tile with a water absorption of 4% and below
(Which includes all vitreous and impervious tiles) D. Tile with a breaking
strength of 275 lbs and above and E All porcelain tile.
3. Because there was no universal bit to drill all types of
tile, Barrett Diamond Products developed the 'TILEBIT' designed to drill ALL
TYPES OF TILE
"faster-easier-cheaper". |
HOW TILE IS
RATED |
Tile is rated by how well it performs in a given
application. The AMERICAN NATIONAL STANDARD
INSTITUTE (ANSI) has established standards and has set forth their standard
specifications ANSI A 137.1 for 8 categories. |
 Typical box markings for tile rating.
The specification categories are:
|
| Abrasion resistance |
Glaze hardness |
| Breaking strength |
Water absorption |
| Thermal shock |
Frost resistance |
| Craze resistance |
Coefficient of friction |
|
The standards that can help indicate
drillability:
|
| Abrasion resistance; ASTM C-1027-84 |
| Glaze hardness; MOHS HARDNESS |
| Breaking strength; ASTM C-648 |
| Water absorption; ASTM C-373 |
