18-inch (Ø450mm) MHT Professional Silver Brazed Segmented Diamond Blade

18-inch ($\varnothing$450mm) MHT Professional Silver Brazed Segmented Diamond Blade is a heavy-duty, commercial-grade cutting disc designed for large-scale masonry, roadwork, and structural concrete cutting. Built for high-depth penetration, it is intended primarily for floor saws (walk-behind saws), heavy bench masonry saws, and high-capacity petrol cut-off saws.

Technical Specifications

Key Performance Characteristics

• High-Strength Silver Brazed Joints: Silver-alloy soldering provides high tensile and torsional bond strength between the diamond segments and the heavy alloy steel core to withstand deep, high-torque cutting forces.

• Deep U-Gullet Slots: Generous spacing between the perimeter segments allows rapid flushing of heavy concrete slurry and prevents thermal stress or core warping during long straight runs.

• Aggressive Cutting Speed: Industrial synthetic diamonds embedded in a hard-wearing metal matrix deliver efficient cutting feed rates through dense aggregates and steel rebar.

Core Applications

1. Concrete Construction: Reinforced concrete slabs, heavy expansion joint cutting, precast concrete beams, and foundation walls.

2. Roadwork & Paving: Asphalt overlays, asphalt over concrete, concrete road beds, and heavy granite/concrete kerbs.

3. Block & Structural Masonry: Large limestone blocks, dense stone lintels, and thick concrete retaining walls.

Safety & Operational Guidelines

• Mandatory Water Coolant: Silver-brazed blades must be operated with continuous water pressure. Running an 18-inch silver-brazed disc dry will melt the braze, causing rapid segment detachment and severe machine or operator hazard.

• Flange & Pin Alignment: On floor saws, ensure the locking pin fits securely into the blade’s drive pin hole to prevent slippage on the arbor.

• In-Line Straight Cuts: Avoid twisting or forcing the machine during deep passes to prevent core bending or side-wall binding.
