Engineering Excellence
High-Performance Specialist Diamond Saw Blades
DURO specialist diamond blades are engineered to perform where standard general-purpose discs fail. Developed in close collaboration with civil engineering contractors, industrial demolition crews, and municipal rescue teams, our specialist blade range combines high-concentration synthetic diamond grit with cobalt-titanium bond matrices and laser-welded segment joins.
Every blade in the DURO specialist lineup undergoes field validation across challenging cut-off applications including heavily reinforced concrete with high-density rebar, ductile iron water pipes, green concrete, abrasive asphalt overlays, granite curbing, and multi-layered structural metals.
Vacuum Brazed Rescue & Steel Blades
Engineered with vacuum-brazed synthetic diamond grains exposed directly along the steel core rim and segment flanks. Designed for rapid emergency rescue cutting, structural steel demolition, and mixed-material substrates.
- Cuts steel section, iron pipe, timber, plastic, rubber, and masonry with one blade
- Eliminates blade shattering associated with conventional bonded abrasive wheels
- Constant cutting depth throughout full operational service life
- Compatible with high-speed cut-off saws and hand-held angle grinders
Heavily Reinforced Concrete Blades
Formulated with a soft, free-cutting metallic bond matrix paired with premium grade synthetic diamonds. Designed to continuously wear away at an optimal rate to expose fresh diamond edges when encountering heavy steel rebar mesh.
- Keyhole slant slotting for rapid swarf clearance and lower thermal friction
- 10mm to 15mm high laser-welded segments preventing segment detachment
- Optimized for floor saws, track saws, and high-power hand saws
- EN 13236 compliance verified through oSa audited test procedures
Asphalt & Abrasive Substrate Blades
Utilizes ultra-hard matrix bonds combined with deep-drop segment technology to withstand continuous contact with highly abrasive silica sand, asphalt aggregates, and green concrete.
- Undercut protective segments safeguard the weld seam against core wear
- Dual-purpose formulas available for alternating asphalt-over-concrete cuts
- Reduced vibration core design extends arbor shaft bearing lifespan
- Available in wet and dry sawing configurations up to 500mm diameter
Ductile Iron & Refractory Brick Discs
Specialized diamond concentration tailored for utility pipe installers, foundry workers, and kiln maintenance teams cutting tough cast ductile iron and dense furnace refractory linings.
- Specialized electroplated and vacuum-brazed hybrid edge geometries
- Prevents pipe pinching and severe blade binding during trenching
- High feed rate with minimal operator hand-arm vibration strain
- Tested under strict ISO 9001 quality management protocol
Global Safety & Quality
oSa Certified Manufacturing & ISO Standards
Safety compliance is non-negotiable when operating high-speed power tools and heavy floor sawing equipment. All DURO diamond blades are produced in manufacturing facilities holding active membership in the Organization for the Safety of Abrasives (oSa®), ensuring rigorous auditing against EN 13236 safety standards.
Our management processes are integrated under ISO 9001 (Quality Management), ISO 14001 (Environmental Responsibility), ISO 45001 (Occupational Health & Safety), and ISO 27001 (Information Security). For overseas distributors and procurement buyers, this guarantees batch-to-batch consistency, full material traceability, and dependable export documentation.

Technical Guidance
Specialist Blades FAQ for Buyers & Engineers
Answers to common technical, safety, and specification questions from industrial procurement teams.
DURO specialist blades feature laser-welded diamond segments, cobalt-titanium alloy bonds, and oSa safety certification, ensuring consistent cut velocity, reduced segment loss, and full compliance with international safety standard EN 13236.
Hard, non-abrasive materials like granite and heavily reinforced concrete require a soft matrix bond that wears evenly to expose fresh diamond grains. Soft, highly abrasive materials like asphalt and green concrete require a hard matrix bond with undercut protection to prevent segment stripping.
Yes, DURO supplies global wholesale partners with customized bore sizes, segment heights up to 15mm, tailored diamond concentrations, and private-label branding.
Laser welded segments join pre-formed diamond/metal matrix blocks to the steel blade body for deep cutting in concrete and masonry. Vacuum brazing fuses raw diamond crystals directly onto the blade core rim and flanks, creating an exposed, aggressive cutting surface capable of slicing through metals, plastics, wood, and mixed construction debris without segment loss.
