Obliterate Thick Concrete Layers and Prep Rough Surfaces Faster with Extended Diamond Durability

Achieve immaculate surface preparation and rapid material removal with the Bosch DC4518 4-1/2 Inch Double Row Segmented Rim Diamond Cup Wheel. 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.

Designed 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.

Key Features

• 18-Segment Double Row Configuration: Maximizes cutting contact for rapid, aggressive material removal while leaving a flat, smooth, polished finish.
• 50% Longer Service Life: Advanced premium diamond pattern matrix technology extends operational longevity versus previous-generation cups.
• Precision Balanced Engineering: Drastically reduces rotational wobble and tool chatter, delivering low-vibration operation to reduce user fatigue.
• Integrated 5-Hole Dust Design: Provides optimal continuous airflow cooling and efficient vacuum debris extraction when paired with a dust shroud.
• Optimized Market Height Profile: Industry-standard thickness ensures flawless fitment with an extensive assortment of surfacing dust collectors.
• Versatile Wet or Dry Application: Performs with outstanding reliability in both dry dustless setups and wet aggregate profiling jobs.
• Universal Machine Compatibility: Engineered explicitly for 4-1/2" hand grinders with a standard 7/8-inch unthreaded center hole arbor fitment.

Specifications

Pro-Tip: When using the DC4518 segmented cup wheel for dry surface leveling, let the weight of the angle grinder do the work instead of pushing down hard. 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.
