The MK Diamond MK-705W 14" Premium Grade Asphalt Blade is built for crews cutting utility trenches, pavement patches, and curb repairs in asphalt on a daily basis. It is MK Diamond's Premium-grade wet asphalt blade, one step below their Supreme-grade MK-710W line, and is sized to fit any 14" walk-behind or handheld cut-off saw rated in its 8-20 hp range.
Built for asphalt, not general demolition
Asphalt behaves differently under a blade than concrete or masonry. Because asphalt is petroleum-bound, friction heat can make it turn viscous, and a hot blade can pinch, melt, and stall mid-cut. The MK-705W is a wet-cutting (W-series) blade for exactly that reason - a steady water flow keeps the segments cool and flushes softened asphalt out of the kerf instead of letting it re-bond to the blade. Typical jobs include:
- Utility and pipe-repair trenching through asphalt roadway and parking lot surfaces
- Square, clean-edged pavement patches ahead of a mill-and-fill or pothole repair
- Curb and gutter cuts where a straight, chip-free edge matters
- Daily production cutting for paving and utility contractors running walk-behind flat saws

Frequently asked questions
Should I cut asphalt wet or dry with this blade?
Wet. The MK-705W is a wet-cutting design, and asphalt itself calls for it: as the blade heats up, asphalt can soften and pinch the segments, stalling the cut. A steady water flow keeps the blade cool and clears melted material from the kerf.
What size saw does the MK-705W 14" fit?
Any 14 inch walk-behind flat saw or handheld cut-off saw rated in the blade's 8-20 hp range.
What is the difference between Premium and Supreme grade for asphalt blades?
MK Diamond positions the MK-705W Premium grade as its mid-tier asphalt blade and the MK-710W Supreme grade as its top tier. Premium grade suits regular trenching and patch work; Supreme grade is built for crews running daily, high-volume production cuts and wanting longer segment life.
Will this blade cut asphalt over concrete?
The MK-705W is built for straight asphalt. For composite asphalt-over-concrete cuts, MK Diamond makes a dedicated MK-625W line engineered for that layered material.
How do I know when the segments need replacing?
The MK-705W ships with 12mm segments. Laser welding keeps the diamond layer bonded to the core through the blade's life, so replace it once segment height is worn down near the steel core or cutting speed drops noticeably with adequate water flow.
