The 14-inch size is the workhorse diameter on most walk-behind pavement saws, and this is MK Diamond's Premium Grade blade in it. The MK-705W is rated one tier above the Standard 700W on MK's published asphalt chart and runs on the same 8 to 20 horsepower, 1-inch arbor platform. Stepping up from 12 inches to 14 inches buys depth of cut, which is what utility and street crews need when a trench has to clear the full mat in one pass.
Built for
- Full-depth utility and trench cuts in asphalt pavement for water, sewer, gas and fiber crews.
- Street openings, patch boxes and saw-cut layout ahead of a mill-and-patch repair.
- Squaring off failed pavement on parking lots, drives and paving jobs before removal.
- Municipal and DOT street department work on walk-behind and cart-mounted wet saws.
- Rental fleets that need a known asphalt blade for the 8 to 20-horsepower saws they already rent out.
Use Cases
The single most expensive mistake in pavement sawing is running the wrong blade in the wrong material. MK Diamond says so directly in its own blade manual: the most frequent problem it sees is a user cutting the wrong material with the wrong blade. Asphalt is abrasive and it loads a cut differently than cured concrete does, which is why MK builds a separate asphalt line and rates the MK-705W as Better on asphalt in its published application chart.
One caution worth reading before you order: MK does not recommend the MK-705W for asphalt over concrete. That job is a different blade in MK's lineup (the 600 series combination blades). If your cut will punch through the mat and into a concrete base, ask us and we will point you at the right part instead.
Getting full life out of it
This is a wet-cutting blade. MK is unambiguous that wet cutting blades can never be run dry, and publishes a water rate of 2 to 4 gallons per minute delivered evenly to both sides of the blade. Water does three jobs at once: it cools the steel core, it keeps the dust signature down, and it flushes the fines out of the kerf. Contractors describe the same thing in their own words - water helps the fines wash out of the cut and makes the blade last.
The two failure modes crews complain about most are both avoidable. A blade that stops cutting has usually glazed over from being forced; MK's guidance is to let the blade cut rather than push it, so fresh diamond keeps exposing. A blade that dies with segment still on it has usually been undercut, where slurry grinds away the core beneath the segments. More water, shallower step-down passes and staying out of the sub-base are the standard fixes.

Frequently asked questions
Why choose a 14-inch blade over a 12-inch?
Depth of cut. A larger diameter reaches deeper on the same saw, which matters when a trench or street opening has to clear the full asphalt mat in one pass rather than two. The tradeoff is that it asks more of the saw.
Can it be run dry?
No. MK states that its wet cutting blades can never be used dry. Feed 2 to 4 gallons of water per minute evenly to both sides of the blade.
Will it cut through to a concrete base?
MK marks the MK-705W as not recommended for asphalt over concrete. If your cut will reach a concrete base, that is a different blade in MK's lineup. Contact us before ordering and we will confirm the correct part.
What horsepower saw does this need?
MK publishes an 8 to 20 horsepower range for the MK-705W family, which covers common walk-behind and cart-mounted wet saws. An underpowered saw will lug and glaze the blade instead of cutting it.
What is the difference between Standard and Premium grade here?
MK's chart ranks the MK-700W Good on asphalt and the MK-705W Better. MK does not publish what physically differs between them, so we will not claim a bond or diamond concentration. What MK does publish is the ranking and the wider size range on the premium family.
