Diamond Blades
Selecting the diamond blade type and grade defines how the blade will perform both in cutting speed and blade life. Selection of the proper diamond blade consists of:
Material to be Cut
Type of Saw Being Used
Horsepower of Saw
Hardness Characteristics of the Material
Performance Expectations
Factors for sawing economy:
Type of Blade
Depth of Cut
Sawing Speed
Characteristics of the Material Being Cut
Blade Speed
WARNING
Operating saw blades at rotational speeds greater than those specified by the manufacture can cause blade damage, and may injure the user or others in the operating area.
A diamond blade’s performance is directly connected to specific peripheral (rim) speeds.
The following shaft rotational speeds have been factory set to ensure optimum blade performance:
•SP118 18” Capacity - 2,836 RPM.
BLADE PLACEMENT
WARNING
Failure to thoroughly inspect the diamond blade for operational safety could result in damage to the blades or the saw and may cause injury to the user or others in the operating area.
