70 Grit 3" 10 Seg Metal - Medium Bond Red

- Mid-fine metal-bond grinding disc for the second-to-last metal step — 70 grit sits between the mid-range cuts (40, 50) and the final 120-grit refinement, smoothing the scratch pattern left by coarser grits while continuing to expose fine aggregate. Standard step in the metal-bond progression before transitioning to resin polishing pads.

- 10-segment configuration for the 3" Redi-Lock platform — ten diamond segments arranged around a 3" / 80mm Redi-Lock or 2-pin compatible plate, designed to fit Husqvarna PG-series, STI/PrepMaster, Stonekor, and similar small-format grinders. The smaller disc format is sized for edge grinders and compact floor machines where the larger 7"–10" tooling won't fit.

- Engineered for medium concrete — medium-hardness concrete (typically 3,000–5,000 PSI, Mohs 5–6) is the most common slab type found on commercial and residential floors. The medium metal bond is balanced for this hardness to give steady cutting speed without premature wear or diamond glazing.

- Counterintuitive but correct: medium bond is the default starting point — most contractors start a new job here and switch to harder (for soft concrete) or softer (for hard concrete) bonds only if testing or visible wear shows the medium bond isn't matched to the floor. The red color code is the universal industry marker for medium-bond tooling.

- Recommended starting grit for small-to-medium aggregate exposure — when the goal is exposed-aggregate finish at the small-to-medium stone size, 70 grit is the typical starting point per industry guidance. For larger aggregate exposure, start coarser (16 or 30 grit metal); for fine salt-and-pepper finishes, start at 120 grit. After this pass, the typical sequence steps up to 120-grit metal, then into resin polishing pads beginning at 50 grit resin.
