25 Grit Arrow Metal Double Segment - Medium Bond - Right

- Aggressive metal-bond grinding segment in arrow geometry for the first cutting pass — 25 grit is the standard starting point for most surface prep and polishing jobs. The cutting surface opens up the concrete, removes coatings, exposes aggregate, and creates the profile needed for subsequent grinding and polishing steps.

- Arrow segment geometry for fast production rates — the arrow-shaped segments are slanted at an angle that lets the tool scrape and grind simultaneously, delivering an aggressive cut while the angled leading edge sweeps debris away from the work area. Arrow segments are specifically engineered to push through epoxy, glue, mastic, and tough surface material faster than standard rectangular or button segments at the same grit. Particularly suited to jobs that combine coating removal with initial concrete prep.

- "Right" = clockwise rotation — direction matters — arrow segments are direction-locked: the angled leading edge cuts during rotation in one specific direction only. Right-rotation tools are for grinders that spin clockwise (viewed from above). Critical rule for planetary / rotary grinders with counter-rotating heads: order half right and half left to balance the machine. Running all same-direction arrow segments on a counter-rotating machine causes severe walking, unbalanced cut, and accelerated tool wear.

- Double-segment configuration for tool life and refinement — two diamond segments per shoe create more surface contact than a single segment, extending tool life and leaving a more uniform scratch pattern. Best paired with larger / heavier walk-behind grinders (25" and up) where the extra contact patch helps the machine pull weight. Medium bond is balanced for typical commercial and residential slabs (3,000–5,000 PSI, Mohs 5–6) — the default choice when slab hardness is unknown.

- The "coating + concrete in one pass" tool — choose arrow geometry over standard round, dot, or rectangular segments when the job involves residual coatings the slab needs cleared during the first metal-bond pass. The arrow's debris-sweeping action prevents loading on softer coating residue while the diamond cut handles the concrete underneath. After this 25-grit pass, the typical sequence steps up through 50, 70, and 120-grit metals (often switching from arrow to button or round geometries for the smoother cut), then into resin polishing pads.
