REFINA PD 23.2 9" Twin Handle Diamond Floor Grinder

The REFINA PD 23.2 is a heavy-duty 230mm diamond floor grinder designed for professional floor preparation where speed, control and a consistent finish matter.

Powered by a 1.5kW direct-drive motor and weighing 42kg, the PD 23.2 combines the weight needed for effective grinding with a stable twin-handle design that gives the operator excellent control across larger areas.

With a preparation rate of up to 40m² per hour, it’s a serious step up from handheld grinding when you're tackling larger areas of concrete, screed and existing floor finishes.

Depending on the tooling fitted, the PD 23.2 can be used for everything from general concrete grinding and levelling to removing latex, adhesive residues, coatings and other stubborn surface contaminants.

An adjustable dust hood and rubber skirt allow the grinder to be connected to a suitable professional dust extractor, helping control airborne dust and keep the working environment cleaner.

The machine is supplied with a 230mm general-purpose 40-grit diamond grinding disc, so it's ready for general concrete and floor preparation work straight out of the box.

Why We Stock It

Floor preparation is one of those jobs where having the right machine can completely change the day.

For smaller areas, a handheld grinder makes perfect sense. Once the floor area starts increasing, however, spending hours working bent over a smaller machine becomes slower, harder on the operator and less efficient.

That's where the PD 23.2 earns its place.

Its 230mm grinding width, 42kg operating weight and twin-handle design make it a proper professional floor preparation machine for contractors who regularly need to grind, level or remove material across larger areas.

More importantly, it isn't limited to one job. By changing the diamond or PCD tooling, the same machine can be configured for different preparation tasks.

One machine. Different tooling. A lot of floor-preparation problems covered.

Compatible Tooling

One of the biggest advantages of the PD 23.2 is its versatility.

Different 230mm diamond and PCD grinding plates can be fitted depending on the material you're trying to grind or remove.

Suitable tooling is available for:

• General concrete grinding

• Aggressive surface removal

• Latex removal

• Adhesive residue removal

• Paint and coating removal

• Epoxy removal

• Fine grinding

• Surface finishing

Choosing the correct tooling allows the PD 23.2 to go from general-purpose concrete grinding to much more aggressive removal work without needing an entirely different machine.

Choosing Your Voltage

The PD 23.2 is available in 110V and 240V versions.

110V: Designed for professional site use and requires a suitable 20A power supply.

240V: Suitable for use from a standard 13A supply.

Please select the required voltage before ordering.

Dust Extraction

For the best results, we recommend using the PD 23.2 with a suitable professional dust extractor.

Correct dust extraction doesn't just help keep the working environment cleaner. It also helps maintain grinding performance by removing airborne and loose material from around the grinding head.

For professional floor preparation, we'd always recommend matching the grinder with an appropriately rated dust extraction system.

The Willow Tree View

The PD 23.2 isn't the machine we'd recommend for somebody who occasionally needs to grind a small area.

That's what handheld grinders are brilliant at.

This is for the floorlayer or contractor who regularly looks at a larger preparation job and thinks:

“I don't want to do all of that on my hands and knees.”

The wider grinding area, machine weight and upright working position make much more sense when preparation becomes a significant part of the job.

Add the ability to change tooling for different substrates and removal tasks, and you've got a machine that can become a genuine workhorse in a professional floor-preparation setup.

Built for proper preparation. Chosen for real jobs.
