On glazed porcelain, the blade decides whether an exposed cut edge looks finished or looks chewed. The MK Diamond MK-415 is a 7-inch continuous-rim wet tile blade built for exactly that work: a super high rim on a thicker core, running wet, cutting clean enough that the edge does not need to be hidden under trim. Tile setters and flooring contractors run it on production jobs where hundreds of cuts have to come off the saw consistently.
Built for
- Cutting glazed porcelain and vitreous tile where a chip-free edge is visible in the finished floor
- High-production commercial tile installations that run a saw all day
- Finish and trim cuts on wall tile, thresholds, and exposed edges
- Any wet tile saw taking a 7-inch blade with a 5/8-inch arbor
- Contractors who would rather buy one blade than grind and polish every cut edge
The continuous rim is the point of difference, and it is a deliberate trade. Segmented and turbo blades cut faster because the gullets clear material aggressively, but that same action chips a glazed face. A continuous rim cuts slower and leaves an edge that needs far less cleanup, which is why contractors on trade forums consistently name continuous rim as the standard for porcelain. On a job where every cut edge is visible, the time saved on finishing is worth more than the time lost at the saw.
This is a wet-cutting blade. Water does two jobs here: it carries the slurry out of the cut and keeps the core from overheating, which is what warps a blade and ruins a cut line. Run it on a saw with a working water feed and keep the reservoir clean. The MK-415 line runs from 7 inches up to 20 inches, so a shop can stay on the same blade series across saw sizes; the 8-inch and 10-inch sizes share the 5/8-inch arbor while the larger sizes step up to a 1-inch arbor.

Frequently asked questions
Can this blade be used dry?
No. The MK-415 is specified as a wet-cutting blade. Running it dry risks overheating the core and ruining both the blade and the cut.
Why a continuous rim instead of a turbo or segmented blade?
A continuous rim cuts more slowly but leaves a far cleaner edge on glazed porcelain. Segmented and turbo blades cut faster and chip the glaze, which costs more time in finishing than it saves at the saw.
What arbor size does it use?
The 7-inch size uses a 5/8-inch arbor. Bushed and special arbors are available from MK Diamond on request.
Will it cut granite or marble?
The MK-415 is specified for porcelain and vitreous tile. MK Diamond builds separate blades for natural stone, so do not assume cross-material use.
How long does the blade last?
MK Diamond does not publish a blade-life figure and neither do the dealers we checked, so we will not quote one. Life depends heavily on material hardness, water flow, and feed rate.
