Engineered to dominate grueling masonry demolition and masonry restoration applications, this commercial-grade grinding disc features 18 rugged, double-row abrasive diamond segments. It is the premier professional solution for smoothly leveling uneven expansion joints, grinding down thick concrete layers, clearing high spots, and scraping away stubborn residual thinset, mortar, flashing, or epoxy coatings. The specialized diamond grit formulation and optimized matrix pattern deliver an outstanding 50% longer operational lifespan compared to previous generational wheels, ensuring maximum utility and cost savings on the jobsite.\u003c\/p\u003e\n\u003cp style=\"font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; line-height: 1.6; color: #333333;\"\u003eDesigned for seamless compatibility with standard small angle grinders and dedicated concrete surfacing dust shrouds, this 4.5-inch diamond grinding cup wheel operates safely at speeds up to 13,200 RPM. Each wheel undergoes a rigorous factory precision-balancing process that drastically reduces axial wobble and operational chatter. This crucial vibration reduction reduces hand-arm fatigue during prolonged structural grinding sessions while protecting your angle grinder's internal motor bearings. Built with a universal 5-hole cooling and extraction geometry, it optimizes airflow to expel harsh silica dust instantly when paired with a dust collection vacuum, supporting a cleaner, highly productive wet or dry environment.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; line-height: 1.6; color: #333333;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e18-Segment Double Row Configuration:\u003c\/strong\u003e Maximizes cutting contact for rapid, aggressive material removal while leaving a flat, smooth, polished finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50% Longer Service Life:\u003c\/strong\u003e Advanced premium diamond pattern matrix technology extends operational longevity versus previous-generation cups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Balanced Engineering:\u003c\/strong\u003e Drastically reduces rotational wobble and tool chatter, delivering low-vibration operation to reduce user fatigue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated 5-Hole Dust Design:\u003c\/strong\u003e Provides optimal continuous airflow cooling and efficient vacuum debris extraction when paired with a dust shroud.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Market Height Profile:\u003c\/strong\u003e Industry-standard thickness ensures flawless fitment with an extensive assortment of surfacing dust collectors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Wet or Dry Application:\u003c\/strong\u003e Performs with outstanding reliability in both dry dustless setups and wet aggregate profiling jobs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Machine Compatibility:\u003c\/strong\u003e Engineered explicitly for 4-1\/2\" hand grinders with a standard 7\/8-inch unthreaded center hole arbor fitment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul style=\"font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; line-height: 1.6; color: #333333;\"\u003e\n\u003cli\u003e(1) DC4518 4-1\/2 In.

Heavy downward pressure creates excessive heat buildup that can glaze over the diamond segments and score the concrete. Maintain a light, sweeping horizontal motion and keep your dust extractor running at peak CFM to continuously cool the cup through the built-in ventilation holes, maximizing segment life and keeping the surface clean.\u003c\/p\u003e","brand":"BOSCH","offers":[{"title":"Default Title","offer_id":52162643951927,"sku":"DC4518","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/files\/Bosch_DC4518_4-1_2_Inch_Double_Row_Segmented_Rim_Diamond_Cup_Wheel_Angle_Grinder_Concrete_Surface_Grinding_Disc_Surface_Prep_7_8_In_Arbor.jpg?v=1779115500","url":"https:\/\/www.1toptools.com\/products\/bosch-dc4518-4-1-2-inch-double-row-segmented-rim-diamond-cup-wheel-angle-grinder-concrete-surface-grinding-disc-surface-prep-7-8-in-arbor","provider":"1 Top Tools","version":"1.0","type":"link"}
