Designed specifically for Bartell grinders and other machines equipped with the Slide-Mag fastening system. \u003cstrong\u003eNot cross-compatible with Lavina dot\/button platforms or Husqvarna Redi-Lock systems\u003c\/strong\u003e — confirm your grinder uses Slide-Mag before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Double-segment configuration for tool life and refinement\u003c\/strong\u003e — 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 \u003cstrong\u003elarger \/ heavier walk-behind grinders (25\" and up)\u003c\/strong\u003e where the extra contact patch helps the machine pull weight. For aggressive stock removal on smaller machines, a single-segment 16 grit cuts faster but wears out sooner.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Engineered for soft-to-medium concrete (Mohs 4–7)\u003c\/strong\u003e — Bartell uses a simplified 3-color bond system distinct from the Lavina\/Elite scheme: \u003cstrong\u003ePurple\u003c\/strong\u003e for soft to medium concrete (most slabs fall in this range, Mohs 4–7), Orange for medium to hard, Green for hard to very hard. Bartell includes a Mohs scratch test kit with its tooling sets specifically so contractors can confirm the right color for the job.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e- Step-zero tool for heavy prep jobs\u003c\/strong\u003e — use this before stepping up to 25-grit when the floor has thick coatings or significant surface irregularities. After the 16-grit opens the floor, the typical sequence moves up through 25, 40, and 80-grit metals, then into transitional and resin polishing pads. Since the vast majority of commercial and residential concrete falls in the Mohs 4–7 range, purple is the default bond most Bartell users keep stocked at this grit.\u003c\/p\u003e","brand":"Bartell Morrison (USA) LLC","offers":[{"title":"Default Title","offer_id":52141661290777,"sku":"16PUR2","price":50.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/9803\/7273\/files\/d6d519b1-99a0-4361-89a3-b0f44b0dee77.png?v=1777484816","url":"https:\/\/shop.simiron.com\/products\/bartell-16-grit-double-segment-purple-slide-mag-for-soft-to-medium-concrete","provider":"Simiron","version":"1.0","type":"link"}
