The EDCO 2EC-NG Electric MAGNA-TRAP Dual-Disc Floor Grinder is the industry benchmark for powerful, versatile, and user-friendly concrete grinding and surface preparation in both commercial and residential applications. With a design focused on productivity, safety, and unrivaled versatility, this wedge-less dual-disc grinder is the professional’s tool of choice for smoothing, leveling, coating removal, joint flattening, and preparing substrates for new coverings or coatings.

Product Overview

The EDCO 2EC-NG features a rugged electric drive available in both 115V/1.5 HP and 230V/3 HP configurations, ensuring emission-free operation and consistent torque—ideal for indoor use or environmentally sensitive projects. Its 21.5" (~22") working width and two counter-rotating magnetic multi-tooling discs enable fast, precise grinding across large, open areas or narrower hallways, providing coverage of 400–500 square feet per hour at a 1/32" depth using Dyma-Serts.

Key Features

• Wedge-Less Magna-Trap System: EDCO’s patented slide-on, wedge-less magna-trap tooling removes the hassle of wooden wedges and allows fast changes between Dyma-Serts, Strip-Serts, Magna-Blades, and polish pads—saving time and reducing downtime.

• Level Grinding Technology: The exclusive EDCO Leveling System allows you to adjust machine height, ensuring flat, uniform results and increasing tooling life.

• Counter-Rotating Discs: Eliminates lateral pull, enhancing control and delivering even, straight passes at all operator skill levels.

• Heavy-Duty Dust Shroud: A Velcro dust skirt easily adjusts to any tooling height and fits both 2" and 3" vacuums, delivering jobsite dust management that meets OSHA silica standards.

• Laser-Cut Weight Tray: A built-in tray accepts up to 80 lbs. of extra weight for maximized downward force, faster removal, and easier control on thick coatings or dense concrete.

• Multi-Vac Port: Accepts various hose diameters for compatibility with most commercial vacuums.

• User Ergonomics: Push handle design, balanced frame, and laser-cut tray make this machine easy to transport and operate in both open floors and tight spaces.

• Water Port: Enables wet grinding for high-heat or dust-sensitive jobs.

Technical Specifications

Performance and Advantages

• Versatile Surface Prep: Levels uneven joints, smooths pitted or rough concrete, removes thin set, mastic, adhesives, epoxy, sealers, paint, and other build-ups—making it perfect for resurfacing, coating prep, and restoration.

• Precise Leveling: Adjustable height and extra weight tray allow for flat, even grinding and tailored aggressiveness on every surface.

• Rapid Accessory Changes: Magna-Trap slide-on design allows tooling rotation or swap-outs in seconds—no tools or wedges needed.

• Superior Dust Management: Fully skirted with Velcro dust shroud, plus vacuum and water ports, for OSHA silica-compliant dust control with both wet and dry options.

• User-Friendly: Counter-rotating discs prevent unwanted movement; balanced frame and ergonomic design mean less fatigue and easier handling for new and seasoned operators alike.

Applications

• Concrete Grinding & Leveling: Warehouse floors, retail spaces, industrial plant maintenance, new slab prep.

• Coating Removal: Paint, sealers, epoxy, thin set, mastic—remove old or failed coatings quickly.

• Trip Hazard Removal: Smooth transitions and flatten surface irregularities between concrete slabs or at expansion joints.

• Surface Polishing & Texturing: Use diamond or carbide tooling for coarse grinding, surface honing, or slip resistance.

• Surface Cleaning: Remove soft materials or ice (in cold storage environments or walkways).

Maintenance & Operator Tips

• Pre-Operation: Inspect belt tension, check and tighten fasteners, grease bearings every 50 hours, rotate or replace tooling for even wear, ensure shroud and vac are properly connected.

• During Use: Position grinder at starting point, bring motor to full speed, and lower slowly onto the surface; sweep side-to-side for uniform finish and avoid forcing the machine.

• After Use: Clean skirt, shroud, and vacuum filters; wipe down tooling discs. Store with cord properly wound, shroud attached, and on a flat surface.

• Cord Use: Use a short, 10-gauge, grounded extension cord (max 100 ft) to prevent voltage drop and motor heating.

• Wet Grinding: Attach water supply to port, use as needed for dust control or to minimize heat on dense or polish jobs.
