350mm Silver Brazed Multi Material Diamond Blade — VCT B1 (VCT15M30350)

The VCT B1 (VCT15M30350) is a 350mm silver brazed multi material diamond blade built for contractors and cutting crews who work across a variety of site materials and cannot carry a different blade for every substrate. Where the specialist VCT blades in this range are optimised for a single material type — old concrete, asphalt, or new concrete specifically — the VCT15M30350 is engineered to perform across the full spectrum of hard, abrasive, and mixed construction materials encountered on South African building and civil sites.

The alternating turbo segment design — clearly visible in the close-up image with its tall and short segment profile — is the key to this versatility. The alternating segment heights create a combination of aggressive cutting teeth and open gullet sections that deliver fast cutting on hard materials while maintaining cooling airflow and debris clearance across softer and more abrasive substrates. This makes the VCT15M30350 a genuinely capable general-purpose 350mm blade for mixed-material sites.

Manufactured under the Vus Cutting Technology house brand with a 15mm silver brazed segment for extended cutting life, this blade is the practical on-site solution for contractors who need one dependable 350mm floor saw blade that handles whatever the job throws at it.

Best For

• Mixed construction sites where multiple material types are cut in a single shift
• Hard and abrasive products including hard aggregate asphalt
• New concrete and old concrete, including hardened slabs and foundations
• Clay pavers and hard paving slabs on road and landscaping projects
• Hard clay and vitrified clay products
• Roof tiles and clay roofing materials
• Reinforced concrete containing rebar and wire mesh
• Refractory materials in industrial applications
• Contractors and plant hire companies who supply one blade type for a wide range of cutting jobs
• Sites where simplifying blade inventory and reducing changeover time is a priority

Alternating Turbo Segment Design — Versatility Built Into the Blade

The distinguishing feature of the VCT15M30350 is its alternating turbo segment profile, visible clearly in the close-up Image 4. Unlike the uniform segment height of standard segmented blades, the alternating design places tall cutting segments between shorter ones in a repeating pattern around the full circumference of the blade.

This geometry achieves two things simultaneously. The taller segments act as primary cutting teeth, making aggressive contact with the material and doing the majority of the cutting work. The shorter segments between them create open channels that function like extended gullets — allowing air circulation, heat dissipation, and debris ejection during the cut. This balance between cutting aggression and thermal management is what allows a single blade to perform acceptably across a wide range of materials rather than being optimised exclusively for one.

On hard, dense materials like old concrete and reinforced slabs, the tall segments provide adequate cutting force. On more abrasive materials like asphalt and clay pavers, the open cooling channels prevent overheating that would otherwise cause premature wear. The result is a blade that adapts to the material rather than requiring the material to be matched to the blade.

Multi Material vs Specialist Blades — When to Choose Each

The VCT B1 multi material blade is the right choice when cutting flexibility matters more than absolute optimisation for one material. Here is a guide to help choose:

• Choose VCT15M30350 (Multi Material) when: You are cutting across multiple material types in a shift, you want to simplify blade inventory, or you are doing short runs on a variety of materials and a specialist blade change is not practical.
• Choose VCT B1 VCT1535030 (Old Concrete / Hard Masonry) when: You are cutting large volumes of old, hardened concrete or hard masonry exclusively and want maximum cutting efficiency on that specific material.
• Choose VCT B1 VCT1535080 (Asphalt / New Concrete — Silver Brazed) when: You are cutting asphalt or freshly poured green concrete exclusively and need deep draft undercut protection for sustained high-volume asphalt cutting.
• Choose TH15ALW350 (Asphalt / New Concrete — Laser Welded) when: You are cutting asphalt or new concrete in high-production environments and require the stronger segment bond and dry-cut flexibility of laser welding.

Technical Specifications

Machine Compatibility

The VCT B1 (VCT15M30350) fits floor saws, road saws, and walk-behind cutting machines with a 25.4mm (1-inch) arbour — the standard bore size on most 350mm / 14-inch floor and road saws used on South African construction sites. Always confirm your machine’s maximum disc diameter and rated operating speed before fitting. Your machine’s rated speed must not exceed 4,366 RPM.

This blade is not suitable for use on hand-held angle grinders. For 230mm angle grinder applications, see the VCT C1 230mm Segmented Diamond Blade in the VCT construction range.

Safety & PPE

Operating a 350mm diamond blade on a floor saw or road saw requires strict safety compliance at all times. Always observe the following:

• Ensure adequate water flow is connected and running before cutting begins — do not run this blade dry
• Wear a full face shield and safety glasses throughout the operation
• Use hearing protection — floor saws and road saws produce sustained high noise levels
• Wear waterproof outerwear, rubber boots, and cut-resistant gloves
• Wear an appropriate dust mask — even with wet cutting, silica-laden slurry dries on surrounding surfaces
• Inspect the blade before every use for cracks, missing segments, or steel core deformation
• Never exceed the maximum operating speed of 4,366 RPM
• Ensure the blade guard is correctly fitted and the blade is properly seated on the machine spindle before starting
• Keep bystanders clear of the cutting area and comply with site safety signage requirements
