YOU WILL NOTICE THE DIFFERENCE
Small, subtle differences in the characteristics of the glass cutting wheel and in the pressure ultimately applied to the glass surface can have a substantial effect in the success of the score, the quality of the cut edge, and minimizing your scrap rate. Selecting the best wheel geometry is only part of the success formula; only consistency of all of the critical dimensions score after score, wheel after wheel will allow you to optimize your process.
MacInnes PRO-SCORE® wheels perform with consistency because:
- There is a unique marriage of tungsten carbide grade and a tightly controlled tip finish at the cutting edge
- All dimensions are held within extremely tight tolerances
- All axle holes are polished to produce smooth movement
while scoring
- Each and every wheel is mounted and tested on glass to insure reproducible performance

MATERIAL AND CUTTING SURFACE FINISHES |
MacInnes Tool Corporation uses a specially
formulated ultra fine-grain tungsten carbide
exclusively for both glass cutting wheels and axles.
Harder and much more wear resistant than steel, this
proprietary grade has been sintered under high
pressure to maximize transverse rupture strength
(resistance to fracture) and to retain its edge
longer than conventional carbide. PRO-SCORE® wheels
can be resharpened without sacrificing quality of
score.
Pro-Score® carbide wheels are offered in three
surface finishes suitable for a range of glass
formulations and cutting conditions. |
 |
Regular (220 Grind)
is the first choice for the vast majority of applications
offering a good blend of traction and durability.
|
 |
Coarse (180 Grind)
should be considered for irregular surfaces or work-piece
geometries such as lamp tubes. Ease of application is
improved but at the sacrifice of resistance to wear.
|
 |
Polished
should be considered to achieve the highest quality and
strongest edges for mirror glass, solar (heat absorbing)
glasses, coated and various specialty glasses. |

Inspections for dimensional conformance are made at each
step in the manufacture of the wheel assuring our customers
of consistent quality from wheel to wheel, shipment to
shipment.
Since the included angle is so critical in demanding high
volume glass production or fabrication, technicians at
MacInnes Tool continuously check the angle using state of
the art microscopy and video inspection techniques to make
sure the angle is accurate and centered on the wheel. In
addition, each and every wheel is painstakingly mounted and
used to actually test cut glass. You are assured of getting
a quality wheel that cuts smoothly, straight and without
"skips."
There is an optimum combination of wheel angle, wheel size
and surface finish for every piece of equipment, every
application. MacInnes technicians will work with you to
determine what works best in your equipment. We do not
subscribe to the theory that "one size fits all" or that
five degrees angles increments are adequate. Over fifty
years we have been in the business of manufacturing tools
for cutting glass. The geometries in the table on the
preceding page have proven to be the most popular. We stock
each of these items to support our general customer base
without any additional charge.
