The EDCO Magna-Trap® 10″ Turbo Grinder – TG-10G is a high‑production gas‑powered concrete grinder designed for aggressive surface preparation, coating removal, and concrete leveling on medium to large projects. With a 10" working width, the TG‑10G can grind approximately 400–500 sq ft per hour at 1/16" depth per pass using diamond tooling, making it up to four times faster than conventional floor grinders.

Overview of the EDCO Magna-Trap® 10″ Turbo Grinder – TG-10G

The Magna-Trap® 10" Turbo Grinder (TG‑10 series) is EDCO’s dedicated turbo grinder platform, available in gas (TG‑10G), electric (TG‑10E), and propane (TG‑10P) power options. The TG‑10G model is the gasoline version, built around a 13 HP Honda engine and EDCO’s Magna‑Trap accessory disc system to tackle tough concrete surfaces quickly.

EDCO markets the TG‑10 as four times faster than conventional grinders, thanks to its 10" turbo disc, high RPM, and optimized weight and balance. It grinds wet or dry, includes a standard vacuum port for dust control, and comes standard with a rigid head assembly (flex head optional on certain configurations).

Magna-Trap® Turbo Grinder Head and Tooling

At the heart of the TG‑10G is EDCO’s Magna‑Trap® turbo grinder head and Multi‑Tooling Disc system.

• 10" Magna-Trap Accessory Disc:

  • Accepts EDCO Magna‑Trap Dyma‑Dots and other Magna‑Trap diamond tooling for grinding, profiling, and light removal.

• Multi-Tooling Disc with carbide pockets (newer packages):

  • Allows you to bolt tungsten carbide scrapers directly onto the disc for aggressive coating and mastic stripping before or during grinding.

Magna-Trap tooling is held magnetically or mechanically on the disc, enabling fast change‑outs and the flexibility to combine different segments and carbides as needed. This modular system is what allows the TG‑10G to perform multiple surface prep tasks with a single machine.

Rigid vs Flex Head Assembly

The EDCO Magna-Trap® 10″ Turbo Grinder – TG-10G is offered primarily with a rigid head assembly, while flex head assemblies are options on some TG‑10 models.

• Rigid head assembly (standard on TG‑10G):

  • Ideal for grinding high spots, expansion joints, joint curls, bridge decks, and rough, uneven concrete surfaces where a flat, aggressively cutting head is required.

• Flex head (optional on certain TG‑10 models):

  • Slightly more forgiving on wavy floors and may be preferred for certain finishing applications.

Most gas TG‑10G units sold for heavy surface prep and removal come with the rigid head, as it maximizes contact, production, and flatness correction.

Rounded Shroud, Edge Grinding, and Dust Control

The Magna-Trap® 10″ Turbo Grinder incorporates a rounded shroud design around the grinding head.

Key benefits:

• Edge grinding: The rounded shroud design allows you to grind within 1/2" of any vertical surface (walls, columns, curbs), reducing edge‑grinding time and additional tooling needs.

• Dust control: The rounded shroud, combined with the standard 2"–3" multi‑vacuum port, helps capture dust more effectively when connected to a suitable dust collector.

Being able to grind close to walls while maintaining dust control is critical on interior projects and occupied spaces, and the TG‑10G’s shroud design is a key feature for both OSHA silica compliance and productivity.

Leveling Kit and Operator Comfort

Modern Magna-Trap TG‑10 grinders, including the TG‑10G, feature EDCO’s leveling kit and improved bearing design.

• Rear wheel‑mounted leveling kit:

  • Lets you easily adjust the grinder disc or multi‑accessory plate height from the rear with a turn‑style knob.

  • Ensures different height diamond accessories can be leveled for even wear and maximum productivity.

• Benefits of proper leveling:

  • Even tooling wear, longer life.

  • Better floor finish with uniform scratch patterns.

• Tapered roller bearings with improved seals:

  • Provide longer life and less maintenance by keeping dust and slurry away from critical bearing surfaces.

EDCO also notes that the TG‑10 design results in less torque on the operator compared to some older grinder styles, improving comfort and control during long shifts.

Typical Applications for the TG-10G Turbo Grinder

The EDCO Magna-Trap® 10″ Turbo Grinder – TG-10G is built for tough concrete surface prep jobs:

Common applications:

• Concrete grinding and leveling:

  • Removing high spots, joint curls, and uneven slabs.

  • Smoothing rough concrete surfaces and bridge decks.

• Coating, adhesive, and mastic removal:

  • Using carbide pockets and scrapers mounted to the Multi‑Tooling Disc to remove glues, coatings, thinset, and mastics before final grinding.

• Surface profiling:

  • Preparing concrete for coatings, sealers, overlays, and self‑leveling underlayments by creating a specified CSP (concrete surface profile).

• Edge and perimeter grinding:

  • Grinding within 1/2" of walls and vertical surfaces reduces the need for additional edge grinders.

The TG‑10G is frequently used by surface prep contractors, flooring installers, concrete repair specialists, and rental houses due to its combination of production speed, versatility, and gas‑powered mobility.

Gasoline Power Advantages (TG-10G vs Electric/Propane)

The TG‑10 family includes electric (TG‑10E), propane (TG‑10P), and gas (TG‑10G) models. The TG‑10G offers several advantages where gasoline power is acceptable:

• No power cords: Greater mobility, ideal for exteriors, large open areas, and sites without convenient 230V electrical service.

• High horsepower: 13 HP Honda engine provides strong torque and maintains RPM under heavy load.

• Fast setup: No need to locate or wire special outlets; just refuel and go.

Electric TG‑10E units are preferred for indoor, low‑emission environments with available 230V power, while propane TG‑10P blends internal combustion with lower emissions for some interior work. The TG‑10G is the best choice for outdoor, heavy‑duty grinding where maximum freedom of movement and power are required.

Productivity and Performance Summary

EDCO, Runyon Surface Prep, and other distributors consistently highlight the TG‑10’s production capabilities:

• 10" working width: Efficient for medium‑sized projects while remaining maneuverable around obstacles.

• 400–500 sq ft/hr at 1/16" cut depth: Four times faster than conventional grinders under typical conditions.

• Up to 1/8" per pass on tough materials: Turbo grinder design and proper tooling allow deeper passes where needed (noted for some TG‑10 electric/gas specs).

This combination of speed, depth capability, and edge access makes the EDCO Magna-Trap® 10″ Turbo Grinder – TG-10G a proven workhorse for demanding concrete surface preparation.
