It is used for friction cutting of cold carbon and alloy steels, usually multiple parts.

Large Friction Saws:

It is generally used for friction cutting of cold carbon and alloy steels in multiple parts. Thinner tooth pitches used to create frictional heat during cutting. High pressure cooling and cleaning of teeth and generous body cooling are vital for the operation of the blade.

Blade Materials:

POWERBLADE Carbon, Manganese Steel, normalized body 22 HRC and flame hardened teeth 48 to 54 HRC. Tough, crack-resistant blade body combined with hard, wear-resistant teeth to provide significantly longer blade life between sharpenings compared to medium carbon manganese steel blades.

Size Range:
  • 1000 mm to 2400 mm diameter (39 to 94 inches)
  • 6 mm to 16 mm thickness (0.236 to 0.63 inch)
  • Tooth Pitch 5 mm to 28 mm (0.2 to 11/8 inch)
Tooth Profiles:
  • Standard profile is 60° Dowel used for both hot and friction cutting
  • Special thread form for special applications
  • 60°Dowel, friction cutting steel pipe
  • Handsaw teeth – solid bars and logs
  • XLR and Skip thread – hot cutting jumbo beam
Blade Body Profiles:

Flat Ground – Normally recommended for solid sticks and logs

Knife Body Profile - Flat Ground

Hollow Turned – Normally recommended for profiles and beams

The blades are precisely machined, balanced and tensioned to ensure even stability, vibration-free operation and accurate cutting at speeds from 4267 to 7620 m/min (14000 to 25000 ft/min).

Small Diameter Friction Saws:
  • 350 mm to 1200 mm diameter (14 to 47 inches)
  • Used for friction cutting of small steel pipes and sections.
Materials:

Chrome Vanadium Steel or Tungsten Molybdenum Steel is usually over 600 mm (24 inches). Hollow profile for clarity. Standard dowel or special thread forms.
