$The VCT B1 (VCT1535030) is a 350mm silver brazed diamond blade built for the most demanding wet cutting applications on South African construction sites. Designed specifically for old concrete and hard masonry — materials that quickly destroy inferior blades — the B1 combines a silver brazed segment bond with a deep 15mm diamond segment to deliver long-lasting, aggressive cutting performance on the hardest, densest site materials. At 350mm, this blade is designed for floor saws, road saws, and walk-behind cutting machines used in high-production environments such as road construction, civil engineering projects, and heavy-duty demolition work. The silver brazing process creates a strong metallurgical bond between the diamond-impregnated segment and the steel core, ensuring the segments remain securely attached even under the sustained heat and vibration generated during deep wet cutting of old, cured concrete. This is a professional-grade blade. The deep 15mm segment height means significantly more cutting life compared to standard 7mm or 10mm segments — making it a cost-effective choice for contractors and hire companies running high-volume cutting operations. Best For • Old and very hard cured concrete — slabs, footings, foundations, and hardened structures • Clay pavers and hard paving slabs on road and civil construction projects • Hard clay and vitrified clay products • Roof tiles and clay roofing materials • Reinforced concrete containing rebar and wire mesh • Refractory materials used in industrial and furnace applications • High-production floor and road saw operations requiring extended blade life • Civil engineering contractors, road-cutting crews, and plant hire companies Why Silver Brazed? Silver brazing is a high-temperature bonding process that fuses the diamond segments to the steel core using a silver-alloy filler metal. This creates a bond that is well-suited to wet cutting applications, where water cooling reduces blade temperature and allows the silver brazed joint to perform reliably over extended use. For old concrete and hard masonry — where cutting resistance is high and blade temperatures build quickly — wet cutting with a silver brazed blade is the preferred approach. The water suppresses dust, cools the blade, and extends both the segment life and the integrity of the brazed bond, resulting in more cuts per blade compared to dry cutting alternatives on the same material. The 15mm segment height on the B1 adds further value: as the outer diamond layer wears through normal use, fresh diamond-impregnated material is continuously exposed, maintaining cutting efficiency deep into the blade’s working life. Technical Specifications Model B1 Product Code VCT1535030 Brand Vus Cutting Technology Diameter (Ø) 350mm Bore / Arbour Size (B) 25.4mm Segment Height (H) 15mm Segment Type Silver Brazed Max Speed 4,366 RPM / 80 m/s Cutting Method Wet cutting Application Old concrete, hard masonry, clay pavers, reinforced concrete, refractory materials Machine Compatibility The VCT B1 is designed for floor saws, road saws, and walk-behind cutting machines with a 25.4mm (1-inch) arbour — the standard bore size on most 350mm floor and road saws. Always confirm your machine’s maximum disc diameter and rated operating speed before fitting. Your machine’s rated speed must not exceed the blade’s maximum speed of 4,366 RPM. This blade is not designed for use on hand-held angle grinders. For 230mm angle grinder blades, see the Earth THDS7223 and other blades in our construction range. Safety & PPE Wet cutting with a floor saw or road saw at 350mm generates significant hazards. Always observe the following before and during use: • Ensure adequate water supply is connected and flowing before cutting begins — never run a wet cutting blade dry • Wear a full face shield and safety glasses to protect against water, slurry, and debris • Use hearing protection — floor saws and road saws produce sustained high noise levels • Wear waterproof outerwear and rubber boots to protect against cutting slurry • Even with wet cutting, wear an appropriate dust mask when slurry dries on site • Inspect the blade before each use for cracks, missing segments, or damage to the steel core • Never exceed the maximum operating speed of 4,366 RPM • Ensure the blade is correctly fitted and the blade guard is in place before starting the machine$ 350mm Silver Brazed Diamond Blade for Old Concrete and Masonry — VCT B1
