The blade decides the cut. Knowing the three main diamond blade types lets you match the blade to the material and stop chipping tile.
Continuous-rim blades
A solid, gap-free diamond rim gives the cleanest, chip-free edge — the go-to for porcelain, ceramic and glass. Run it wet for the best finish and longest life. This is the blade most tile pros reach for first.
Turbo-rim blades
A serrated rim with vents cuts faster than continuous while staying fairly clean. Good all-rounder for porcelain and harder materials when you want speed without big chips. Can run wet or dry in short bursts.
Segmented blades
Gaps (“teeth”) between segments clear debris and cut fast and aggressive — ideal for concrete, pavers, brick and stone, but they chip tile, so they're not for finish cuts on porcelain.
Match blade to material
- Porcelain & glass: continuous-rim, wet.
- General porcelain/stone, faster pace: turbo.
- Pavers, concrete, stone slabs: segmented.
Care = clean cuts + longer life
Keep the blade cool (water), don't force the cut, and dress a glazed blade on a dressing stone to re-expose the diamonds. A clean blade outperforms a pricier worn one. See our tile saw buying guide and shop blades in the tiling tools collection.
FAQ
Best diamond blade for porcelain? A continuous-rim blade run wet — it gives the cleanest, chip-free edge.
Continuous or turbo? Continuous for the cleanest finish; turbo when you want more speed and can accept a slightly rougher edge.
Why is my blade chipping tile? Often a segmented blade on porcelain, a worn/glazed blade, or cutting dry — switch to a continuous-rim blade and keep it wet.
