4. Diamond grit: D427 or D301

5. Dry grinding is used in small cutting job, Wet grinding is recommended for long working life.

Notice for safe grinding:

Safe operating practices must be part of every grinding wheel user’s operation. The greatest efficiency and lowest overall abrasive cost can be realized only if proven care and use techniques become standard practice.
• Be sure to read any safety material/ guidelines provided with the abrasive product.
• Always check the wheel for cracks or damage before use.
• Before mounting the wheel, use a tachometer to measure the spindle speed.
• Ensure the mounting flanges, backplate or adapter supplied by the machine manufacturer are properly used and kept in
good condition. ANSI Safety Requirement B7.1 provides wheel mounting requirements.
Check mounting flanges for equal and correct diameter.
• Never use a grinding wheel with a rated speed less than the grinder.
• Always mount, true and dress the wheel in conformance with the guidelines published in the ANSI Safety Requirements B7.1.
• Ensure the correct wheel guard is in place before starting the wheel. Allow the wheel to come up to full operating speed before
starting to grind for a minimum of one minute, and stand out of the plane of rotation.
• NEVER use a high speed air sander as a portable grinder.
• NEVER exceed the maximum operating speed marked on the wheel being used. The following formula may be used to calculate wheel speed:
SFPM = Spindle Speed in RPM x Wheel
Diameter in inches x .262
• Avoid dropping or bumping the wheel.
• When not using the wheel, store the wheel in its original packing materials
