Blastrac 10 in L-Segment Grinding Blade
Blastrac 10 in L-Segment Grinding Blade is a heavy-duty rotary diamond grinding disc engineered for aggressive surface preparation, concrete leveling, and tough coating removal on walk-behind single-head floor grinders. Built with 20 high-grade diamond segments shaped in an angled “L” (chevron) configuration and arranged in a staggered pattern across the face, this tool maximizes cutting efficiency while maintaining a balanced, uniform grind across uneven slabs. The angled geometry of each L-segment shears through stubborn thinset, adhesives, epoxy remnants, and surface high spots, channeling concrete swarf outward to keep the diamond matrix open and cutting freely.
Weighing 6 lbs on a rigid steel backing plate, the disc provides solid downward stability that resists bouncing and reduces chatter during high-production concrete grinding. The mounting plate incorporates multiple precision bolt-hole patterns and a center pilot bore, ensuring secure, direct attachment to standard 10-inch rotary grinder drive plates. Suitable for both wet and dry floor preparation workflows, the 20-segment layout delivers an optimal balance of aggressive stock removal, extended tool service life, and an open mechanical profile ready for subsequent coatings or polishing stages.
Main Features
- 20 Heavy-Duty L-Segments: Angled chevron-style diamond segments shear through coatings and concrete high spots with reduced surface drag.
- Staggered Multi-Ring Layout: Concentric segment arrangement distributes grinding pressure evenly across the 10-inch path to minimize deep swirl marks.
- Universal Bolt-Hole Pattern: Machined with a center pilot bore and multiple bolt holes for secure mounting on standard 10″ grinder drive heads.
- Heavy 6 lb Steel Base: Adds stable downward mass directly over the grinding zone to dampen machine vibration and prevent plate deflection.
- Efficient Swarf Evacuation: Angled segment channels prevent diamond glazing by directing pulverized dust and abrasive fines away from the contact path.
- Wet & Dry Operation: Engineered to perform reliably in dry floor preparation with vacuum dust extractors or under wet grinding conditions.
