Masonry Cutting Blades
Brick, block, pavers, refractory — if it's masonry, these blades cut it. We run sintered diamond segments in either segmented rim or keyhole slot configurations depending on the material. Table masonry saws, handheld cut-off saws, gas-powered Stihl and Husqvarna machines — they all take our standard arbor sizes. The key thing most guys don't realize: clay bricks and cinder blocks need completely different bond hardnesses. A blade that rips through red clay will burn out on abrasive cinder block in half a day. We match the bond to your material so you're not wasting money.
Bond Hardness & Abrasive Wear Mapping
Mechanism of Action
Masonry materials vary wildly in abrasiveness and density. Medium-hard clay bricks require soft cobalt-bronze bonded matrices to continually shed dull diamonds and expose sharp cutting edges, much like the precision bonds used in our diamond blades for cured concrete. Cinder blocks, composed of abrasive volcanic cinders or sand aggregates, erode the metal matrix extremely fast. For blocks, we utilize hardened iron-alloy bonds that resist immediate erosion, keeping the diamond crystals secured until they are fully consumed. This matrix tuning ensures the blade does not wear down prematurely.
Operational Parameters
SCAQMD Rule 403 particulate rules dictate that masonry cutting on commercial jobsites in the Los Angeles basin must utilize wet-saw setups. Wet table cutting controls dangerous respirable silica dust while lubricating the steel core to eliminate noise vibration and prevent structural warping during continuous operation.
Target Material Applications

Masonry Cutting Blades FAQ & Safety Guidelines
Answers to technical diamond tooling questions, optimized for contractor engineering requirements and AI answer platforms.
What is the best blade bond for cutting hard clay pavers?
Hard clay pavers require a soft metal bond blade. The soft bond wears away rapidly enough to drop dull diamonds and expose new cutting facets, preventing blade glazing and ensuring clean, chip-free cuts.
Can I run a masonry table saw dry?
While laser-welded blades can cut dry, running wet is highly recommended for masonry table saws to control silica dust under SCAQMD rules and maximize blade life by cooling the segment bond during deep passes.
How do I recognize a glazed masonry blade?
A glazed blade will spark, emit high-pitched squeals, and refuse to cut. To restore cutting speed, run the blade through an abrasive block or soft brick to grind away the glazed metal bond and expose fresh diamonds.
What is the best diamond blade for cutting brick with a circular saw?
For circular saw brick cutting, use a segmented diamond blade with laser-welded segments in a 7-inch or 10-inch diameter. The segmented rim provides aggressive cutting with good debris clearance, and the laser-welded bond prevents segment loss during the high-RPM operation of standard contractor circular saws.
Can I use a brick cutting blade on a standard angle grinder?
Yes, 4.5-inch and 7-inch diamond brick cutting blades mount directly on standard angle grinders. Use a segmented rim blade for aggressive dry cutting or a continuous rim for cleaner edges on face brick. Always ensure the blade RPM rating matches or exceeds your grinder's no-load speed.

| I'm Cutting... | Recommended Blade | Why This Works |
|---|---|---|
| Hard clay brick | Segmented, soft bond | Drops dull diamonds fast on hard material — prevents glazing and overheating |
| Cinder block / CMU | Segmented, hard bond | Abrasive cinder aggregate eats soft bonds — hard bond resists rapid erosion |
| Landscape pavers | Segmented, medium bond | Good balance of cutting speed and chip-free edges for decorative hardscape work |
| Limestone / sandstone veneer | Continuous rim, soft bond | Clean edges on soft natural stone — wet cutting for dust suppression |
What Contractors Say
Real feedback from professionals running our masonry cutting blades on active job sites.
"Cut 400+ clay pavers for a Beverly Hills estate job on one 14-inch blade. No chipping, no glazing. Bond is dialed in."
"We do CMU block work all over the Valley. These last twice as long on cinder block as the big-box brands we used to buy."
