Deep production cuts in asphalt are where blade choice stops being a detail. At 26 inches a blade is reaching most of the way through a full depth pavement section, and every inch of that cut is abrasive material actively eroding the bond. The MK Diamond MK-710W is the Supreme grade of MK asphalt blades, carrying the heaviest diamond concentration in the asphalt line, and this is the 26-inch size in the narrower 0.155-inch kerf. It is built for the road, highway and utility contractor running a high horsepower wet saw on long cuts.
Use cases
- Full depth roadway and highway cuts on asphalt pavement
- Long trenching runs for utility installation and repair
- Patch boundary cuts on large scale street and airfield maintenance
- Production asphalt sawing where blade life per cut governs the cost of the job
Kerf and why this one is narrow
MK Diamond publishes the 26-inch MK-710W in two widths, this 0.155-inch blade and a 0.187-inch version. A narrower kerf removes less material, which means the saw expends less energy per foot of cut and the blade tends to advance faster for a given horsepower. The wider kerf buys rigidity and a longer wearing segment, which matters on the deepest and most demanding cuts. If your saw is at the lower end of its power range, the narrower blade is usually the one that cuts better; if you are cutting to full depth all day on a large machine, the wider one generally lasts longer.
Grade and horsepower
MK Diamond grades its blades by diamond concentration in three tiers, Standard, Premium and Supreme. Supreme is the top tier and is intended for high production work on saws with the power to use it. MK rates the 710W series for saws in the 12 to 25 horsepower range. A Supreme grade blade on an underpowered saw is a poor investment, because the extra diamond can only pay for itself when the machine can drive the blade at the rate it is designed to cut.
Wet cutting
The W designation marks this as a wet cutting blade. Water cools the core and flushes asphalt cuttings out of the kerf, which matters more in asphalt than in most materials because the fines are sticky and will pack a dry cut. The saw must deliver a continuous supply of water to both sides of the blade for the whole cut.

Frequently asked questions
What is the difference between the 0.155-inch and 0.187-inch 26-inch blades?
Kerf width. The 0.155-inch blade removes less material and generally advances faster for a given horsepower. The 0.187-inch blade is more rigid and carries a wider wearing segment, which suits the deepest and heaviest production cuts.
Does this blade require water?
Yes. The W designation marks it as a wet cutting blade, and the saw must supply continuous water to the blade throughout the cut.
What does Supreme grade mean?
Supreme is the top of MK Diamond three grade structure, above Standard and Premium, and denotes the highest diamond concentration. It is intended for high production cutting on saws with sufficient horsepower to drive it.
What size saw does this blade need?
MK rates the 710W series for saws in the 12 to 25 horsepower range. Confirm your saw accepts a 26-inch blade on a 1-inch arbor and falls within that power range before ordering.
How deep will a 26-inch blade cut?
Depth of cut is set by the saw rather than the blade, since the flange and guard determine how much of the blade can enter the material. Check the maximum depth published for your machine at a 26-inch blade diameter.
