Disston Precision provides manufactured custom saw blades & steel parts of the highest quality. These photos demonstrate the care and steps taken to provide precision steel products.
This image shows a Disston friction
circular saw blade with an 84 inch
O.D. being repaired by welding
for a U.S. steel mill.
When raw material is received
from the mill, we often use an
to cut saw blades’ outer
and inner diameters.
This image shows the flame cutting
of a saw blade. We also use plasma,
laser, and water jet when needed.
All work is completed in-house
in our Philadelphia, PA manufacturing
facility using time honored
methods - since 1840.
This image shows our CNC drilling machine to drill holes in die cutting plates. Hole accuracy is +/- 0.010 inches. We are not limited by number of holes or configuration.
This image shows our austentizing furnace on the left. Steel product moves out of the furnace and along the conveyor to the oil quench tank. This process increases hardness of the steel up to 62 HRc. View more on Heat Treating.
