Masonry contractors reach for an 18 inch MK-10 when they are cutting brick all day on a table saw and the blade they have been using keeps glazing over on the hard, dense units. MK Diamond describes the MK-10 as a soft matrix blade built for fast, efficient cutting and long life on all types of brick, and it calls out harder brick specifically. That soft bond is the whole point: a softer matrix releases worn diamond and exposes fresh cutting edge instead of polishing smooth, which is what kills a general-purpose blade in hard clay brick.

Choosing a brick blade
Bond hardness is the decision that matters on brick, and it runs opposite to intuition: hard, dense material wants a soft bond, and soft, abrasive material wants a hard bond. MK bonds the MK-10 soft precisely because fired brick is hard. A soft matrix keeps shedding worn diamond so fresh edge is always exposed, instead of polishing over into a blade that rubs rather than cuts. If your cutting is mostly block or cured concrete rather than brick, MK publishes the MK-30 for brick and block together and the MK-50 for concrete block, and either will outlast an MK-10 in that material.
Safe operation
This is a wet-cutting blade and it must be run with a continuous water feed. Running a wet blade dry is the single most common cause of segment loss, core warping and a scrapped blade, and it also puts respirable crystalline silica into the air. Water does two jobs at once: it carries heat out of the core and it knocks the dust down at the cut. Confirm your saw's arbor matches the blade before mounting, seat the blade flat against the flange, and never exceed the maximum operating speed stamped on the blade.
Frequently asked questions
Will the MK-10 cut concrete block as well as brick?
It will pass through block, but it is not the right tool for it. MK bonds the MK-10 soft for brick. On block and cured concrete a soft bond wears away much faster than it needs to. MK publishes the MK-30 for brick and block together and the MK-50 for concrete block, and either will outlast an MK-10 in that material.
Can I run this blade dry?
No. The MK-10 is a wet-cutting segmented rim blade. It needs continuous water at the cut to carry heat out of the steel core and flush the slurry. Running it dry will cost you segments and can warp the core.
What arbor does the 18 inch MK-10 use?
One inch. MK publishes the 18 inch and 20 inch MK-10 with a 1 inch arbor, and the 10 inch version with a 5/8 inch arbor. Check your saw before ordering, since the two are not interchangeable without a bushing.
How much diamond am I actually buying?
The MK-10 carries a 10 mm segment height. That is the depth of diamond-bearing segment available to wear down before the blade reaches the core and is finished.
Discount Cleaning Products is an authorized MK Diamond dealer. We stock the contractor blade lines rather than drop-shipping whatever a marketplace listing happens to carry, so the part number you order is the part number MK prints in its own catalog. Our US-based team can confirm arbor size, kerf and horsepower fit against your saw before you buy, and can help you match bond hardness to the aggregate you are actually cutting.
