450mm Three-Phase Planetary Concrete Grinder Hire
Our 450mm three-phase planetary concrete grinder provides increased productivity for medium and large concrete floor preparation projects.
It is suitable for residential, commercial and industrial applications where a smaller single-phase grinder may take too long. The planetary grinding system provides consistent coverage across the floor, making the machine suitable for coating removal, concrete preparation and polishing applications.
Concrete Grinder Hire Australia can supply the grinder with an appropriately sized H-Class dust extractor, three-phase generator and diamond tooling selected for your particular concrete.
Call 1300 792 207 to discuss your project or request a hire quote.
What Can the 450mm Concrete Grinder Be Used For?
The 450mm planetary grinder can be configured for applications including:
-
Removing epoxy and other floor coatings
-
Removing tile adhesive and carpet glue
-
Preparing concrete for epoxy or polyurethane
-
Grinding rain-damaged concrete
-
Removing surface contamination and weak concrete
-
Correcting uneven concrete and high spots
-
Preparing commercial and industrial floors
-
Grind-and-seal floor preparation
-
Concrete honing and polishing
-
Preparing concrete for new floor coverings
The correct diamonds will depend on the hardness of the concrete, the material being removed and the finish required.
Productive Grinder for Medium and Large Floors
The 450mm grinding width makes this machine more productive than a smaller single-head grinder while remaining manageable on many residential and commercial projects.
It is particularly suitable for:
-
Large garages
-
Residential renovations
-
Retail spaces
-
Restaurants and commercial kitchens
-
Workshops and sheds
-
Offices and showrooms
-
Warehouses and factories
-
Medium-sized coating-removal projects
-
Concrete polishing projects
For small rooms or restricted-access areas, our 250mm single-phase grinder may be more practical. For very large industrial areas, the Husqvarna PG 830 can provide substantially greater productivity.
Three-Phase Power Requirements
The 450mm concrete grinder requires a suitable three-phase power supply.
Before hiring, tell us what power is available on site so we can confirm the required connection. If suitable three-phase power is unavailable, we can supply a compatible three-phase generator as part of the equipment package.
The generator must be correctly sized for the grinder and any supporting equipment. We will help you select the appropriate setup.
H-Class Dust Extractor Hire
Concrete grinding creates hazardous fine dust, so the grinder should be connected to an appropriately sized H-Class dust extractor.
Our hire packages can include:
-
H-Class dust extraction
-
Grinder and vacuum hoses
-
Diamond grinding tooling
-
Dust-management accessories
-
Three-phase generator
-
Setup and operating guidance
Correct dust extraction helps control airborne contamination while allowing the grinder to operate effectively.
Diamond Tooling Matched to the Application
Concrete hardness and surface conditions can vary considerably between projects. Using unsuitable diamonds can cause slow grinding, excessive wear or glazing.
We can recommend tooling for:
-
Hard, medium or soft concrete
-
Epoxy and coating removal
-
Tile adhesive removal
-
General concrete grinding
-
Surface preparation
-
Grind-and-seal projects
-
Concrete honing and polishing
-
Different stages of the polishing process
Our concrete grinding and polishing experience helps ensure you receive the appropriate machine and diamond combination.
Is the 450mm Grinder Right for Your Project?

The area is too large for a 250mm grinder
-
You need to remove a coating efficiently
-
A consistent surface profile is important
-
You are preparing a floor for epoxy
-
You are completing a grind-and-seal finish
-
You are polishing concrete
-
Three-phase power is available

Frequently Asked Questions
What power does the 450mm grinder require?
The grinder requires an appropriate three-phase electrical supply. Tell us what connection is available on site so we can confirm compatibility.
Can you supply a three-phase generator?
Yes. We can supply a correctly sized three-phase generator when suitable site power is unavailable.
Can the 450mm grinder remove epoxy?
Yes. It can remove many epoxy and floor-coating systems when fitted with appropriate diamond tooling. Removal speed depends on the coating type, thickness and condition.
Can it remove tile adhesive and carpet glue?
Yes. The grinder can be configured with tooling suitable for removing various adhesives and preparing the underlying concrete.
Do I need an H-Class vacuum?
An appropriately sized H-Class dust extractor is strongly recommended for dry concrete grinding. We can supply the grinder and vacuum as a matched package.
Are diamond tools included?
Diamond tooling is selected according to the concrete hardness, existing surface and required finish. We will explain the suitable tooling and applicable charges when preparing the quote.
Can the 450mm grinder polish concrete?
Yes. The planetary grinding system can be used for concrete honing and polishing with the correct sequence of diamond tooling.
Is the 450mm grinder suitable for DIY customers?
Because it requires three-phase power and is more powerful than the 250mm machine, suitability depends on the customer, project and site. Contact us so we can determine the safest and most practical setup.
Should I hire the 250mm or 450mm grinder?
The 250mm grinder is generally more suitable for small areas, restricted access and sites with only single-phase power. The 450mm grinder provides greater productivity and more consistent coverage across medium and large floors.
When should I use the Husqvarna PG830 instead?
The PG830 is generally better suited to large commercial and industrial floors where maximum productivity is required. We can compare the expected project time and hire package before recommending a machine.
