A chipped edge on a box of porcelain tile costs more than the blade that caused it. The MK Diamond MK-215 is a premium-grade continuous rim wet cutting blade built for exactly that problem: it produces a smooth, chip-free edge on tile, marble and dense stone where a segmented or turbo blade would leave a ragged cut that has to be hidden or thrown away. This is the 8-inch size, part number 131631, with a .060-inch kerf and a 5/8" arbor.
Built for
- Porcelain and ceramic floor and wall tile, including dense, hard-bodied porcelain.
- Marble, granite and other natural stone tile where edge quality is visible in the finished job.
- Finish cuts and exposed edges that will not be covered by trim, bullnose or grout.
- Miter and rip cuts on most 7-inch and 8-inch wet tile saws.
- Tile and stone shops that need a repeatable, chip-free cut rather than a fast rough cut.
Why a continuous rim, and why premium grade
A continuous rim has no gullets - the diamond edge runs unbroken around the blade. Segmented and turbo blades cut faster because the gaps clear material and air-cool the core, but every gap is an interruption that hammers the tile edge as it passes. On soft materials that is invisible. On glazed porcelain it produces the chipping that ruins a finish cut. The MK-215's unbroken rim keeps the edge in constant contact, which is what delivers the smooth cut this blade is known for.
The trade-off is that a continuous rim has to be cooled by water, not air. The MK-215 is a wet cutting blade only. Running it dry will overheat the core, glaze the bond and end the blade's useful life quickly - so a tile saw with a working water pump or reservoir is a requirement, not a suggestion.
Premium grade in MK's lineup sits above the standard tile blades in diamond concentration and bond quality. In practice that shows up as more cuts before the blade slows, and as consistent performance on dense floor materials that dull a cheaper blade after a few boxes of tile.

Frequently asked questions
Can I use this blade dry?
No. The MK-215 is a wet cutting blade only. A continuous rim has no gullets to move air through the cut, so water is the only cooling path. Running it dry will overheat the core and glaze the bond, ending the blade's life very quickly.
Why choose a continuous rim over a turbo or segmented blade?
A continuous rim gives the smoothest, most chip-free edge because the diamond edge never leaves the material. Turbo and segmented blades cut faster but their gullets chip glazed surfaces. Use a continuous rim for finish cuts and visible edges, and a faster blade for rough cuts that will be covered.
What arbor does this blade use and can it be changed?
This part is supplied with a 5/8" arbor. Stock arbors can be bushed down to smaller sizes, and special arbors are available on request - specify what you need at the time of order.
Will it cut porcelain without chipping?
Yes, that is the blade's main purpose. The MK-215 is rated for smooth, chip-free cutting on tile and other stone materials and performs well on dense floor materials. Feed rate still matters - forcing any blade through hard porcelain will chip it, so let the blade cut at its own pace.
What is the difference between premium and standard grade MK tile blades?
Premium grade uses higher diamond concentration and a better bond than standard grade. The practical difference is cut life and consistency on dense material: a premium blade keeps cutting cleanly through more tile before it starts to slow.
