No, this 300mm blade is designed for petrol cut-off saws and has a 20mm bore, which is generally not compatible with standard angle grinders.
The maximum operating speed is 5,100 rpm. Never exceed this speed as it can lead to blade failure.
The blade is designed for general purpose use, but always refer to your petrol saw manufacturer's guidelines regarding wet vs. dry operation for specific materials.
While it is designed for concrete and bricks, it is best suited for general masonry; for heavily reinforced concrete, ensure your saw has the necessary power.
The blade should be replaced when the diamond segments have worn down to approximately 1-2mm or if the steel core begins to show significant damage.
Check that the blade is properly centered on the spindle and the mounting flange is tightened correctly.
The diamond segments may have glazed over; cut into a soft abrasive material like sandstone to re-expose the diamonds.
Check that you are not applying too much pressure; let the blade do the work and ensure proper debris clearing.
Before installation, ensure the saw is powered down and the spark plug is disconnected. Verify that the 20mm bore fits your saw's drive spindle perfectly; never force a blade onto a spindle. When mounting, ensure the directional arrow on the blade matches the rotation of the saw. Regularly inspect the blade for cracks or missing segments before starting work. After use, clear any residual grit from the gullets and store the blade in a dry place to prevent corrosion of the steel center.
