A Disc Cutter (or Concrete Saw) is a handheld power tool designed often used in construction and landscaping for cutting hard materials such as bricks, blocks, pavers, concrete, tiles, natural stone and structural metals and pipework.

Usually handheld, they’ve been a favourite tool of many tradesmen for decades thanks to their ability to cut through tough surfaces with relative ease.

Disc cutters typically use a circular diamond tipped steel blade to deliver fast, precise cuts through tough surfaces.

Disc cutters are used in a variety of industries and for numerous applications such as:
Construction & Demolition: These hard-wearing, high-performing tools are essential to the construction industry and used in projects that require precision cutting through hard materials.
Landscaping: Disc cutters enable the user to create precise straight cuts in a variety of materials such as paving stones, sandstone, concrete slabs.
DIY Projects: Disc cutters can be used by competent DIY enthusiasts for a variety of home improvement projects such as installing a patio or pathway, or installing tile flooring.

An Electric Disc Cutter is a plug-in masonry or concrete saw that delivers powerful cutting performance without the noise, fumes, or maintenance of petrol models.

Evolution’s electric cutters are perfect for indoor and outdoor use, quick setup, and clean operation.

Electric disc cutters are usually lighter, more compact and easier to handle than petrol ones, making them a better choice for general work and projects that require more precision.

They also produce less noise and emissions than petrol disc cutters, making them more environmentally friendly. Electric disc cutters also provide instant torque at all times and don’t require revving up to start a cut.

Petrol-powered disc cutters use a fuel and oil mix that requires mixing before use; they produce more noise, exhaust fumes and are usually heavier and larger than electric disc cutters. They do provide the ability to be used in places where there is no power and the largest petrol models can provide more power than their electric counterparts.

Yes, with the right guidance and safety precautions, disc cutters are straightforward to use. Both DIYers and professionals can operate them effectively. However as with any bladed power tool they can be very dangerous.

Due to the exposed blade and high cutting power, it’s essential to read the manufacturer's manual, follow safety instructions, always wear protective gear, and start with lighter tasks, or seek help from someone with experience if you're new to the tool.

As a minimum, always wear:

• Eye Protection: Safety glasses or goggles or a face shield are crucial to protect your eyes from flying particles.
• Dust Mask: Disc Cutters (particularly if dry cutting) will produce a significant amount of dust. An FFP3-rated dust mask or respirator are required to prevent inhalation of potentially hazardous particles
  Hearing protection:
• Even electric and battery powered cutters can be very loud, so earplugs or ear defenders are important to protect your hearing.
• Gloves: These will help protect your hands from cuts, abrasions, and burns from sparks and hot debris.
  Sturdy Footwear:
• Work boots or sturdy shoes will protect your feet from falling objects and debris.
• Long sleeves and trousers: Can help protect your skin from sparks and flying debris.

Water suppression It’s a system that sprays water onto the blade during cutting to reduce the amount of dust emitted into the air. This keeps the workspace cleaner and improves visibility. Water suppression also cools the blade and extends the lifespan of both the blade and the saw.

Water suppression is a legal requirement on construction sites for health and safety compliance.

The R260DCT-Li, R300DCT+ and the R350DCT models all feature water suppression .

Both the R350DCT and the cordless battery-powered R260DCT-Li feature our new automatic water feed valve for the most efficient water suppression. The automatic valve lets the water flow as soon as the blade starts spinning and cuts the water off when you release the power. There's also an independent flow rate control valve, so you can 'set and forget' to get perfect cuts every time.
The Evolution R300DCT+ includes dual-sided water-fed dust suppression, but not our automatic on/off feature.
All our disc cutters featuring water suppression connect to a hose or pressurised bottle and uses brass fittings for durability.

Dry cutting:

• Relies on the blades rotation to air cool the blade. This generates significant amounts of dust, which can be a health hazard and reduce visibility.
• Can lead to faster blade wear due to heat build up
• Generally faster cutting speeds and easier setup
  

Wet cutting:

• Uses water to suppress dust, reduce friction and cool the blade,
  Improved blade life due to better cooling and lubrication.
• Cleaner, safer, and can result in a better finish
• Wet cutting is preferred for prolonged or indoor use.

All our disc cutters are built for handling these types of projects. The choice of cutter depends on the size of your project, how regularly you will use the saw and whether you are a tradesperson or DIYer.
