Sterling SAR SA Semi-Automatic Aluminium Circular Saw
The Sterling SAR semi-automatic range of circular saws are designed for working with aluminium sections and extrusions. All models feature high blade speeds and are semi-automatic operated with a full enclosures for ultimate safety. These machines use TCT toothed cutting blades which are available in a range of tooth pitches depending on the material section and required finish.

The Sterling SAR semi-automatic range of circular saws are designed for working with aluminium sections and extrusions. All models feature high blade speeds and are semi-automatic operated with a full enclosures for ultimate safety. These machines use TCT toothed cutting blades which are available in a range of tooth pitches depending on the material section and required finish. The up-stroking 550 blade has a speed of 3000RPM and comes complete with pneumatic horizontal clamps and 2m of roller track as standard.
Looking to further increase the efficiency in your workshop? Additional roller track for the entry and exit of your saw can help improve efficiency further still. With the roller track in place, workers can quickly and effectively load and unload material. Coupled with measuring systems workers can work faster and more accurately.
Why does Aluminium cutting require Extraction?
The dust from cutting Aluminium is highly flammable. It can ignite spontaneously in air. It will also react with water to generate flammable gaseous hydrogen and heat.
How Dust Explosions Occur
In addition to the familiar fire triangle of oxygen, heat, and fuel (the dust), dispersion of dust particles in sufficient quantity and concentration can cause rapid combustion known as a deflagration. If the event is confined by an enclosure such as a building, room, vessel, or process equipment, the resulting pressure rise may cause an explosion. These five factors (oxygen, heat, fuel, dispersion, and confinement) are known as the “Dust Explosion Pentagon”. If one element of the pentagon is missing, an explosion cannot occur.
Catastrophic Secondary Explosions
An initial (primary) explosion in processing equipment or in an area where fugitive dust has accumulated may dislodge more accumulated dust into the air or damage a containment system (such as a duct, vessel, or collector). As a result, if ignited, the additional dust dispersed into the air may cause one or more secondary explosions. These can be far more destructive than a primary explosion due to the increased quantity and concentration of dispersed combustible dust. Many deaths in past accidents, as well as other damage, have been caused by secondary explosions.
We therefore strongly recommend that any and all Aluminium cutting equipment is supplied with an extraction system of some kind. We have a system set-up for the SRA Upcutting Saw range, speak to a member of the sales team for more information.
