Most site cutting happens where there is no water hookup and no time to rig one. The MK Diamond MK-404D is the MK supreme grade high speed line for exactly that situation, and part number 136770 is the 10-inch size. MK describes the series as a general purpose, high speed blade for concrete and masonry materials, and it is laser welded for dry cutting. Masonry contractors, general contractors and remodelers put this size on hand-held cut-off saws, circular saws and small table saws for everyday work: concrete, brick, block, plaster and stucco, cut fast, with the saw carried to the work rather than the other way round.
Built for
- Hand-held cut-off saw and circular saw work on brick, block and concrete
- Trimming block and brick to fit on a wall that is already going up
- Cutting openings and chases through plaster and stucco during remodels
- Punch-list and repair cutting where setting up water is not practical
- General contractors who want one blade that covers most masonry on site
What sets this blade apart
The useful thing about a dry rated blade is that it is not restricted to dry cutting. The industry rule runs one way only: a dry blade can be run wet, but a wet blade cannot be run dry. So this blade covers the water-fed setup as well, and adding water on a long cut is the cheapest way to extend its life. Where dry cutting does cost you is heat, which is why technique matters more than it does on a wet saw: work in intermittent passes and let the blade spin free in air between cuts so the core sheds heat. The laser welded segments are the joint that makes dry running safe in the first place, and the 10mm segment height is the usable diamond depth that determines how long the blade stays in service.

Choosing the right size in this series
MK publishes the MK-404D across a wide range, from 4-inch up to 20-inch. Several diameters exist in more than one width and arbor, and a trailing letter in the part number marks an arbor variant rather than a different blade, so ordering by MK part number is the reliable way to get the arbor you need.
Frequently asked questions
Can this blade be used with water?
Yes. A dry rated blade can be run wet and will usually last longer for it, because water carries away the heat that wears a blade. The reverse is not true: a wet-only blade must never be run dry.
How do I get the most life out of a dry cutting blade?
Cut in intermittent passes rather than one long plunge, and let the blade run free in air for a few seconds between passes so it can cool. Continuous dry cutting is what overheats a core and causes premature segment loss.
What arbor does part 136770 use?
MK Diamond publishes part 136770 with a DM-5/8-inch arbor, .090-inch width and a 10mm segment height. Check the arbor on your saw before ordering, since this series is published in several arbor variants.
What materials does the MK-404D cut?
MK lists it as a general purpose high speed blade for concrete and masonry materials, covering concrete, brick, block, plaster and stucco. For extremely hard refractory brick or for granite and stone, MK publishes dedicated series with bonds matched to those materials.
Does dry cutting create a dust problem?
Yes, and it should be planned for. Dry cutting masonry produces significantly more airborne dust than wet cutting, so dust extraction on the saw and respiratory protection are the normal precautions on an enclosed or occupied site.
