what is a diamond wall saw blade

Diamond wall saw blades are large diamond circular saw blades designed for installation in wall saws cutting machine (floor  saws machine, wire saw cutting machine) and for cutting vertical surfaces such as concrete, reinforced concrete, and masonry(Horizontal walls can also be cut).

 

I. Core Definition and Features

 

Diamond wall saw blades are large, specialized diamond circular saw blades designed for efficient, smooth, and deep cuts on vertical surfaces such as walls and bridge piers.

 

Compared to smaller saw blades used in handheld saws, they offer several distinct advantages:

• Large Diameter: Diameters typically range from 600mm to 1400mm or even larger to accommodate varying cutting depths.
• Thick Base(thick steel body): The steel base is thicker(4.0 to 6.5mm) and more robust to withstand significant torque and prevent deformation when cutting deep grooves.
• Huice Company can customize the production of diamond wall saw blades with a segment thickness of 4.0mm to 6.5mm for customers.
• Highly Professional: The segment formula (diamond concentration, base hardness) and structural design are specifically optimized for the characteristics of the wall material.

 

 

 

II. Main Components

 

1) Steel Base(steel body):

• This is the skeleton of the saw blade, typically made of high-strength, high-toughness alloy steel.
• The base has heat sinks/silencers to dissipate heat during high-speed rotation, reduce noise, and aid chip removal.
• The core of the base is the mounting hole, which must be precisely matched to the size and type of the wall saw spindle.

HuiceTools has rich experience and high cost-effectiveness in producing high-quality diamond wall saw blades for multiple brands.

 

 

2) wall saw blade Diamond Segment:

• This is the part that performs the cutting task and is welded to the edge of the base.
• Diamond Grains: Industrial-grade synthetic diamonds, used as the abrasive material.
• Matrix Material: An alloy sintered from metal powder (typically cobalt, copper, iron, tungsten carbide, etc.) that encapsulates and secures the diamond grains. The matrix's hardness and wear resistance are crucial; it must wear at an appropriate rate to continuously reveal new, sharp diamond edges.

Huice Company produces uniformly distributed(arix diamond segment, matrix diamond segment) diamond segment wall saw blades, which cut smoothly and efficiently. Long service life. OEM for multiple brands in Europe, America, Southeast Asia, and the Middle East. Stable performance and high cost-effectiveness.

 

 

III. Key Technologies and Types

The core technology of wall saw blades lies in their "segment formula," the combination of diamond and matrix. Different types of saw blades are selected depending on the material being cut:

 

1) For soft materials (such as asphalt, soft brick, and porous concrete):

• Soft matrix: Wears faster, allowing new diamonds to be quickly exposed and maintaining a sharp edge.
• Larger diamond grit: More aggressive and faster cutting speed.

 

2) For hard materials (such as hard concrete and granite aggregate):

• Hard carcass: More wear-resistant, preventing the cutter head from wearing out too quickly due to the abrasiveness of the hard material.
• Finer diamond grit: Provides smoother cuts and longer life.

 

3) For reinforced concrete:

• This is the most common application. The cutter head formulation needs to balance cutting capabilities for both concrete and rebar.
• The carcass needs to be sufficiently tough to prevent shredding or excessive wear when cutting rebar.
• A medium-hard carcass and high-strength diamonds are typically used.

 

4) For reinforced/high-strength materials:

• Carcasses containing ultra-hard particles such as tungsten carbide are used to counteract the wear of the rebar and extend its life.

 

IV. Key Points for Selecting a Wall Saw Blade

Choosing the right wall saw blade is crucial for ensuring efficiency, cost, and cut quality:

1. Diameter: Determines the maximum depth of a single cut. Typically, choose a saw blade that is 25-50mm larger than the desired cutting depth to allow for cooling water and chip removal.
2. Aperture: This must be identical to the spindle diameter of the wall saw equipment. Common options include 40mm and 50mm.
3. Choosing a professional and experienced diamond wall saw blade manufacturer, such as Huicetools, will result in higher cost-effectiveness and safety.
4. Blade Type/Composition: Choose based on the materials you most commonly cut (ask the supplier or refer to the product manual).
5. Water-Cooled vs. Dry Cutting:

• Most wall saw blades are water-cooled, requiring a continuous water supply to cool the diamonds (to prevent overheating and burnout) and suppress dust. This is standard and environmentally friendly practice.
• Dry cutting is rarely used: it is only used for specific, small, shallow cuts and is significantly detrimental to blade life.
• Huice Company customizes dry cut diamond wall saw blades for customers. Dry cut diamond wall saw blades require higher strength and toughness of the steel base(steel body,substrate), so the price of dry cut diamond wall saw blades is slightly higher.

V. Application Scenarios

 

Diamond wall saw blades are widely used in:

• Building renovation: opening doors and windows, and expanding spaces.
• Municipal engineering: demolition and reconstruction of roads and bridges.
• Tunnel construction: creating passageways and ventilation openings.
• Accident rescue: quickly creating rescue routes through walls after earthquakes and fires.
• Equipment Installation: Opening holes for large pipes and ventilation systems.
