The MK Diamond MK-200 8-inch tile blade is the blade a tile setter reaches for when the cut has to look finished, not just fit. It is a continuous rim wet cutting blade built for smooth, chip-free cuts in ceramic, porcelain, marble and other stone, and MK rates the series as excellent on dense floor materials. Part number 137158 is the 8-inch size on a 5/8-inch arbor.
The MK-200 is MK Diamond's standard grade continuous rim wet cutting tile blade, and the continuous rim is the reason it lands on finish work: an unbroken diamond edge leaves no segment gullets to hammer the glaze, so cuts come off the saw smooth enough to set without a second pass on a stone or a grinder. MK rates the series for tile, marble and other stone, and calls it out as an especially strong performer on dense floor materials, which is the category most likely to chip with a cheap blade.
Use Cases
- Straight and diagonal cuts in ceramic and porcelain floor and wall tile on a wet table saw
- Marble, travertine and other dimension stone where a chipped edge cannot be hidden by grout
- Dense pavers and quarry tile that dull a general purpose blade quickly
- Backsplash and bathroom wall tile where the exposed cut edge stays visible
- Remodel and punch-list work where one blade has to cover several tile bodies on the same job
Why this size
The 8-inch size fits compact bench-top and portable wet tile saws that take a 5/8-inch arbor, which is the format most remodelers and one-truck tile crews carry to a job. It is the practical choice for wall tile, small-format floor tile and cut-in work where a 10-inch saw is more machine than the room needs.

Frequently asked questions
What does the 8 mm rim height mean for blade life?
Rim height is the depth of usable diamond above the steel core. At 8 mm the MK-200 carries a full-height rim for its class, so there is real material to wear through before the blade reaches the core. Once the rim wears down near the core the blade is finished and should be replaced rather than pushed.
Can this blade be used dry?
No. The MK-200 is a wet cutting blade. Running a continuous rim blade dry removes the cooling and flushing that water provides, and heat is the most common cause of premature blade failure, showing up as discoloration of the steel core just under the rim. Keep a steady water supply on both sides of the blade for the whole cut.
Why is my porcelain still chipping?
Chipping on hard porcelain usually traces to feed rate, water volume or an unsupported tile edge rather than the blade itself. Slow the last inch of the cut, keep the tile flat against the table and fence, make sure water is reaching the rim and not just the tray, and cut with the finished face up on a table saw so any breakout lands on the back.
Does MK offer other arbor sizes for this blade?
MK Diamond states that special arbors are available on request, and that stock arbors can be bushed down to smaller sizes if you specify that at the time of order. Contact us before ordering if your saw needs a size other than the stock arbor listed above.
