FAQs

What is a rock saw?

A rock saw is a heavy-duty cutting machine designed to slice through hard materials such as rock, stone, asphalt and concrete.

This revolutionary attachment typically mounts to machinery like excavators, skid steers or compact tracked loaders, using a large circular blade to make precise, straight cuts.

How does a rock saw blade differ from a diamond saw blade?

A tungsten rock saw blade and a diamond saw blade are designed for different cutting conditions, and each has clear strengths when matched to the right application.

A rock saw blade uses tough tungsten carbide teeth that cut by chipping and shearing material away. This cutting action makes tungsten blades highly effective in softer to medium-hard rock, limestone, sandstone, asphalt and mixed ground conditions. They deliver faster cutting speeds in these materials, cope well with variable substrates and debris, and are generally more cost-effective to purchase and maintain.

On the other hand, a diamond saw blade cuts by grinding through material using synthetic diamond crystals bonded into the cutting edge. This gives diamond blades exceptional abrasion resistance and makes them perfect for very hard materials like granite and reinforced concrete, where consistent hardness and precision are key.

In short, tungsten blades excel in productivity and versatility across softer and mixed materials, while diamond blades are best suited to continuous cutting in very hard or heavily reinforced surfaces.

What applications is a rock saw used for?

Rock saws are generally used in industries where accuracy, depth control and clean edges are essential, such as civil construction, earthworks, and quarrying.

Common applications include:

• Trenching for utilities such as water, gas, electrical and fibre
• Cutting asphalt and concrete for roadworks and repairs
• Quarrying and stone cutting
• Precision trenching in rock or highly compacted material

A rock saw’s ability to cut deep, straight lines makes it ideal for projects where precision reduces rework and material waste.

How do I choose the best rock saw for my project?

Choosing the right rock saw depends on several factors, including:

• Cutting depth required (e.g. 450 mm vs 600 mm)
• Material type (rock, asphalt, plain or reinforced concrete)
• Host machine capabilities, including hydraulic flow and pressure
• Job frequency and scale, such as occasional trenching versus daily civil works

Matching the rock saw’s hydraulic requirements to your machine is crucial. An undersized setup will reduce performance, while an oversized attachment may damage your equipment.

What hydraulic flow is required?

Adequate hydraulic flow ensures the saw’s blade maintains cutting speed and avoids stalling under load.

The required hydraulic flow varies according to cutting depth:

• 450 mm cutting depth: 60–90 litres per minute (L/min)
• 600 mm cutting depth: 80–130 litres per minute (L/min)

What hydraulic pressure is required?

The hydraulic pressure required for effective cutting depends on the depth:

• 450 mm cutting depth: 175–242 bar
• 600 mm cutting depth: 207–275 bar

Operating below these pressure ranges can lead to poor cutting performance and excessive wear on the blade.

What hydraulic power is required?

Hydraulic power combines flow and pressure to deliver cutting force. Requirements are as follows:

• 450 mm cutting depth: 27 kW
• 600 mm cutting depth: 31 kW

Ensuring your machine can supply this level of power is critical for safe, efficient operation and consistent cutting results.
