7" Cup Wheel, Arrow, Medium Bond 30 Grit

- Aggressive metal-bond diamond cup wheel for 7" hand grinders — designed for fast stock removal on concrete and masonry. The 30-grit metal-bonded diamonds tear through epoxy, paint, glue, mastic, and surface deformities efficiently, making this a go-to choice for coating removal and slab prep before refinement.

- Arrow segment geometry for fast production rates — the arrow-shaped segments are slanted at an angle that allows the wheel to 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 and glue faster than standard rectangular or turbo segments at the same grit.

- Medium bond for the most common concrete hardness — 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. On much softer concrete, the medium bond will wear out faster; on much harder concrete, it may glaze and lose cutting action. Run a Mohs scratch test if slab hardness is in question.

- 5/8"-11 threaded arbor for direct grinder mounting — fits any 7" hand grinder with a 5/8"-11 threaded spindle, no flange or backing pad required. Always verify the wheel's stamped maximum RPM against your grinder's rated speed before use. Suitable for wet or dry grinding, though dust shrouds plus HEPA vacuum are required for indoor work under OSHA silica standard 29 CFR 1926.1153.

- Specialist tool for coating removal jobs — choose arrow-segment over double-row when the primary task is epoxy, glue, mastic, or paint removal rather than general concrete grinding. The aggressive sweep action excels at lifting and clearing softer coating debris, where standard double-row wheels can clog or burnish. After this pass, the typical sequence steps up through finer cup wheels or transitions to walk-behind floor grinder tooling for the rest of the job.
