Helix Grind and Scrape Plate for Efficient Floor Work
National Flooring Equipment Helix Grind and Scrape Plate
Product Overview
The National Flooring Equipment Helix Grind and Scrape Plate is a versatile tooling accessory designed for the Helix planetary concrete grinder. With its flexible tooling arrangement, the plate allows contractors to switch between aggressive surface removal and more controlled grinding, polishing, or sanding applications.
The plate can operate with tooling mounted directly to it for active grinding and scraping, or with the satellite assembly installed for passive planetary grinding. Its Morflex couplers help the tooling follow floor contours while reducing shock transferred to the operator and machine.
This makes the Helix Grind & Scrape Plate a useful foundation for contractors who need one tooling system to handle multiple surface-preparation tasks.

National's documentation specifies that the plate is intended for machines capable of accepting a 16-inch plate with a standard 3¼-inch hub and includes three satellite plates.
Active Grinding and Scraping
The Grind & Scrape Plate can be used without the satellites for active/direct grinding, scraping, removal, and surface preparation. National describes this configuration as quicker and more aggressive than passive planetary grinding.
Compatible tooling can include:
Metal-bond diamonds
Carbide tooling
PCD tooling
Directional tooling
This configuration is particularly useful when the priority is aggressive material removal or creating a stronger concrete profile before a new coating.
Passive Planetary Grinding
With the satellite assembly installed, the Helix can operate in a passive planetary configuration. Tooling attached to the free-spinning satellites can produce a more controlled and random scratch pattern across the floor.
This setup is useful for applications where the operator wants to refine an existing surface rather than perform the most aggressive possible removal. National also describes the passive configuration as suitable for polishing and sanding without leaving the same type of swirl pattern associated with some conventional setups.
Morflex Couplers
The plate incorporates Morflex couplers designed to provide flexibility between the tooling assembly and floor surface.
These couplers allow the tooling to follow floor contours, helping maintain more consistent contact in low areas. They also help reduce shock transmitted back into the machine and operator during use.
Flexible Surface-Preparation Platform
One of the main advantages of the 402757 plate is its ability to accommodate different tooling approaches. A contractor can configure the Helix for:
Aggressive coating removal
Concrete grinding
Adhesive or material scraping
Surface preparation before coatings
Polishing
Sanding
General concrete profiling
National's Helix system supports a range of tooling, including PCDs and metal-bond diamonds, allowing the machine to be configured according to the material being removed and the desired surface profile.
Satellite Tooling
The plate includes three satellite plates that can be attached or removed using cotter pins. This allows operators to change between active/direct tooling and passive planetary tooling without replacing the complete machine.
The satellite arrangement is also useful when working with diamond tooling for surface refinement and polishing applications.
Quick Mounting System
A sliding latch is incorporated into the plate to make mounting and dismounting more convenient. This helps reduce setup time when changing tooling configurations for different stages of a flooring project.
Before changing tooling, however, the Helix should always be powered down and disconnected according to the manufacturer's safety procedure.
Typical Applications
The Helix Grind & Scrape Plate is suited to professional surface-preparation work such as:
Concrete grinding
Coating removal
Adhesive removal
Concrete profiling
Surface preparation before coatings
Carbide scraping
PCD scraping
Polishing
Sanding
Refinishing and renovation projects
The appropriate tooling should be selected based on the material, substrate hardness, desired removal rate, and required final surface profile. National specifically notes that tooling choice for coating removal depends on the coating, concrete underneath, and desired result.
Compatibility
The 402757 plate is designed for the National Flooring Equipment Helix grinder. National lists the Grind & Scrape Plate as included equipment on the Helix, and its current Helix documentation identifies the machine as a 16-inch planetary grinder.
The plate is also described in National's tooling documentation as suitable for machines large enough to accept a 16-inch plate with a standard 3¼-inch hub.
Important Operating Notes
Before installing or changing tooling:
Disconnect the Helix from electrical power.
Remove the safety key according to the operating procedure.
Allow recently used tooling to cool before handling it.
Wear appropriate gloves when handling tooling.
Keep hands and fingers clear of pinch points.
Inspect magnets, couplers, satellites, pins, and mounting hardware before use.
Make sure tooling is properly secured before operating the machine.
Use appropriate dust collection for the material being removed.
Select tooling appropriate for the substrate and desired surface profile.
National's Helix manual specifically warns that tooling can become hot during operation and should be handled from the sides while keeping fingers clear of pinch points.
What Is Included?
The 402757 Helix Grind & Scrape Plate assembly includes:
Grind & Scrape Plate
3 satellite plates
Morflex coupler components
Satellite attachment hardware/cotter pins
Sliding-latch mounting arrangement
The exact tooling segments used for a particular grinding, scraping, or polishing application are selected separately according to the job requirements.
Why Choose the Helix Grind & Scrape Plate?
The National Flooring Equipment 402757 Helix Grind & Scrape Plate gives contractors a flexible tooling platform instead of limiting the Helix to one surface-preparation method.
Its combination of direct/aggressive grinding capability, passive planetary operation, magnetic tooling, Morflex couplers, and removable satellites makes it suitable for projects ranging from tough coating removal to concrete preparation and finishing work.
