Sandwich Diamond Segment For Granite Block Cutting

A sandwich diamond segment adopts a three-layer composite structure: two outer layers with higher diamond concentration and harder metal bond, plus one softer, lower-concentration middle layer. When cutting stone, the middle layer wears away faster than the outer layers. This automatically forms an in-built water channel to cool diamonds and discharge stone dust, while the outer diamond layers keep performing the cutting work. At HuiceTools, we precisely match the wear rate of each layer for stable cutting performance.

A single-layer diamond segment has one uniform bond and diamond concentration across the whole segment, with no self-formed groove. The sandwich type is three-layer structured. It creates an automatic cooling groove during cutting, runs with less vibration, delivers cleaner cuts and maintains more consistent cutting speed. Single-layer segments are simpler and cheaper, but tend to heat up faster and produce more chipping on hard granite.

The middle layer uses a softer metal bond with lower diamond concentration. It abrades preferentially under cutting friction, while the two outer cutting layers wear much slower. The differential wear creates the middle groove automatically. This is the core design feature, not a defect.

It is mainly designed for hard, abrasive natural stone. Typical materials include granite, basalt, gabbro and hard quartzite. HuiceTools can adjust the segment formula to fit different hardness and abrasiveness of stone.

No, it is not limited to granite. It also works well on basalt, gabbro and other hard igneous stones. But it is not the first pick for soft stone or reinforced concrete, where other segment types perform better.

Technically it can cut marble, but it is not the optimal choice. Marble is soft and less abrasive. The sandwich groove structure brings limited benefit here; single-layer segments are usually more cost-effective for marble cutting.

It is widely equipped on quarry block saws, multi-blade gang saws, bridge saws and silent saw blades for granite block processing. These machines require continuous, high-volume cutting of hard stone blocks.

Not recommended. Its core advantage comes from the water channel formed by the middle groove. Without water cooling, the diamond grains will overheat, graphitize and blunt rapidly, leading to short service life and risk of segment burning. It is designed for wet cutting.

It is sintered metal bond, mixed with iron, copper, tin, cobalt and other metal powders. The outer layers and middle layer use different bond formulas to control their respective wear speed. HuiceTools develops exclusive bond recipes for quarry cutting.

It forms auto cooling and swarf removal grooves, reduces cutting vibration and stone chipping, maintains steady self-sharpening, runs straighter with less blade wobble and delivers high efficiency on hard granite. It also produces lower cutting noise than ordinary single-layer segments.

Service life depends on granite hardness, abrasiveness, cutting speed, water supply and machine condition. On medium-hard granite for quarry block cutting, well-formulated sandwich segments from HuiceTools offer longer lifespan than regular single-layer segments under the same working conditions. We can provide reference life data based on your local stone sample.

Yes. HuiceTools is a professional diamond segment manufacturer with rich R&D experience. We support full customization: segment dimension, layer thickness ratio, diamond concentration, bond formula and shape to match your saw blade and stone.

For large granite block cutting in quarries, sandwich segments are excellent for balanced cooling, low vibration and stable straight cutting. Arix segments adopt ordered diamond arrangement for faster cutting speed. If your priority is stable cutting, less chipping and long life, choose sandwich segments. If you pursue maximum cutting speed, Arix is a better option. HuiceTools supplies both types for quarry clients.

High concentration suits soft, highly abrasive granite for longer life. Lower concentration gives faster cutting speed on extra-hard, less abrasive granite. The two outer cutting layers usually carry the main diamond concentration while the middle layer keeps low concentration for fast wear. Our technical team at HuiceTools can recommend the right concentration after knowing your stone type and cutting target.
