In the preparation and polishing of concrete surfaces, the design of metal bond diamond tools is crucial for achieving desired grinding results. While the bond and grit size impact the tool's effectiveness, the physical shape, or segment design, influences grinding efficiency, wear patterns, and adaptability to various surface types. Recognizing these differences enables contractors to optimize their processes for improved efficiency and finish quality.

Arrow-shaped segments are often utilized for aggressive grinding and removing coatings. Their pointed design focuses pressure on a small area, allowing for quick cutting into hard surfaces or the removal of tough materials like epoxy or paint. This makes arrow segments grinding tools particularly effective during the initial grinding phases or when significant material removal is required in a short timeframe.

Rectangular or bar segments provide a more uniform and consistent grinding effect. These shapes distribute pressure evenly across the surface, making them ideal for medium grinding or smoothing after aggressive removal. They help minimize scratch depth and are frequently used to prepare floors for finer grit levels or polishing stages. Their uniform wear pattern also enhances the longevity of the tool.

Round or button segments are generally used for light grinding or honing. These tools create minimal scratching and are excellent for refining surfaces or working with softer concrete. Due to their smaller contact area, round segments grinding discs can closely follow surface variations, yielding better results in detailed areas or around edges. However, they are less effective for heavy material removal.

Some tools feature a combination of different segment shapes on a single plate, allowing for both grinding strength and surface refinement in one step. For instance, a mix of arrow and rectangular segments can enable a tool to grind aggressively while still achieving a relatively smooth surface finish. The choice of configuration depends on the specific goals of the job, whether it involves coating removal, leveling, or preparing for polishing.

Choosing the right segment shape goes beyond just material removal; it also involves considerations of efficiency, consistency, and surface readiness. By aligning the tool shape with the specific task and condition of the concrete, professionals can enhance performance and prolong the lifespan of both the tools and the flooring system.
