Fit and compatibility
This blade is made for hand-held grinders. Confirm that your grinder accepts a 4-inch blade on a 5/8-11 threaded spindle and that the guard fits. Other MK-404DV sizes carry different part numbers and some use a 7/8-5/8 arbor, so check the arbor before you order.
Getting the most from the blade
Keep the guard in place, let the blade cut instead of forcing it, and follow your grinder maker's speed and safety guidance. Cutting concrete and asphalt creates dust, so wear eye, hearing and respiratory protection.
