The Marcrist AS750 asphalt blade is built for cutting asphalt and green concrete quickly and cleanly. If you have spent any time cutting road surfaces or freshly laid material, you will know that not every blade is up to it. Asphalt is abrasive and sticky by nature, and undercutting is a genuine problem that can write off a blade well before its time. The AS750 addresses this directly with a drop segment design that keeps the core protected and extends blade life considerably.
Marcrist is a well-regarded name in the diamond blade market, and the AS750 sits firmly in the professional end of their range. The high precision armoured core gives it the structural rigidity needed for sustained cutting under load, while the 10mm diamond segments provide both depth and durability. It is compliant with EN 13236, the European standard for diamond products used in hand-held and walk-behind machines, which matters on sites where equipment certification is checked.
What Makes the Marcrist AS750 Asphalt Blade Worth Using
One thing that genuinely makes a difference on site is noise. Blade noise is one of those things you stop noticing until you use something quieter, and the AS750 is designed with reduced noise during operation. Not silent, obviously, it is still a diamond blade cutting tarmac, but noticeably less punishing than a lot of the competition.
The self-cooling design is equally practical. Heat is the enemy of any diamond blade, and asphalt generates plenty of it. The AS750 can be used wet or dry, so you have the option to run water if you are working somewhere that allows it, or run dry when site conditions make wet cutting awkward. Either way, the blade is designed to manage heat rather than just tolerate it.
Available in a Range of Sizes
The AS750 comes in a wide range of diameters from 300mm right up to 600mm, with multiple bore sizes including 20mm, 22mm and 25mm. Whether you are running a smaller cut-off saw or a larger floor saw, there is a size to suit. The marcrist as750 asphalt blade is backed by a performance and money back guarantee, which is the sort of thing that reads as a throwaway line until you actually need to use it.
If you are regularly cutting road surfaces, carriageways, or laying drainage through tarmac, this blade is a sound choice. It does the job efficiently and lasts well when used correctly.
Pro Tip: Always uncoil your water supply hose fully before wet cutting and keep the flow consistent throughout the cut: intermittent water flow is a common cause of premature segment wear on asphalt blades.
The Marcrist AS750 is used primarily for cutting asphalt road surfaces, car parks, footpaths and driveways. It handles green concrete well too, which makes it a useful blade during groundworks and drainage installation where fresh concrete and tarmac are both present on the same job. Road repair gangs, utilities contractors and groundworkers are the main users, typically running the blade on petrol cut-off saws or electric floor saws depending on the job size.
It is also used on highway maintenance work, expansion joint cutting, and patching operations where a clean, defined cut edge is needed. The range of bore sizes means it fits a broad selection of machines without the need for reducers in most cases.

Not suitable for: Not suitable for cutting cured concrete, granite, or masonry. For those materials, a blade specified for hard aggregate or stone cutting will perform significantly better and last longer.
Fit the correct bore size for your machine and check that the blade diameter does not exceed the machine's rated capacity. Ensure all guards are in place before starting. If cutting wet, get the water flow running before the blade contacts the material, not after.
Let the blade reach full speed before starting the cut. Apply steady, consistent forward pressure and allow the blade to do the work rather than forcing it. On asphalt, aggressive downward pressure causes heat build-up and segment wear faster than most people expect. Keep cuts in a straight line where possible and avoid twisting the blade in the cut.
After use, run the blade briefly on a soft abrasive surface such as a sand and cement block if the segments feel glazed over. This re-exposes the diamond matrix and keeps the blade cutting freely.
Check the blade diameter and bore size match your machine's specifications before fitting
Mount the blade securely with the arrow indicating direction of rotation matching the machine's spindle direction
Ensure all blade guards are correctly fitted and secure
If wet cutting, start the water supply flowing before the blade contacts the surface
Bring the blade to full operating speed before beginning the cut
Apply steady, even forward pressure and let the blade cut at its own pace
Keep the cut line straight and avoid any lateral force or blade twist in the kerf
After cutting, allow the blade to spin down fully before setting the machine down
If segments appear glazed, dress the blade on a soft abrasive block to restore cutting performance
Can the Marcrist AS750 be used on cured concrete as well as asphalt?
It is rated for asphalt and green concrete. Cured or hardened concrete is a different material with harder aggregate, and using an asphalt blade on it will wear the segments down quickly. If you are cutting cured concrete, you need a blade specified for that purpose.
Which bore size should I order for my cut-off saw?
Check your machine's arbor size before ordering. The AS750 is available with 20mm, 22mm and 25mm bore options. Most Stihl and Husqvarna petrol cut-off saws use a 20mm bore, but always confirm against your machine's manual rather than assuming, as fitting a blade with the wrong bore is a safety issue.
The Marcrist AS750 uses a sintered diamond segment construction with a 10mm segment height, bonded to a high precision armoured steel core. The drop segment configuration is the key design feature, lowering the risk of core undercutting in abrasive materials like asphalt. The blade meets EN 13236, the harmonised European standard for diamond tools used on hand-held and machine-guided power tools, covering both safety and performance requirements.
