Magnetic Grinding Shoes

Magnetic grinding shoes offer a fast, tool-free segment change system for professional concrete grinding contractors across Australia and internationally. Compatible with a wide range of floor grinding machines, they deliver consistent cutting performance for grinding, coating removal, and surface preparation on hard-to-soft concrete.

Our range covers multiple segment shapes – including rectangle, hexagon and button – across super soft, soft, medium and hard options and grit sizes from 16 to 120. Whether you're removing a heavy coating or refining a surface before polish, there's a segment matched to your concrete and application.

For heavy coating and epoxy removal, pair with our PCD Diamond Tools.

Magnetic grinding shoes are a key part of concrete grinding tools, used for surface preparation, coating removal, and floor grinding. Designed for quick-change magnetic plates, they allow fast installation and minimal downtime on site.

Double W Segment Faster cutting with increased surface contact, stable grinding performance and improved cooling. Super Soft, Soft, Medium, Hard 16, 30
Double Hexagon Segment Controlled, consistent grinding with smooth scratch refinement for mid-stage surface preparation. Soft, Medium, Hard 60
Double Button Segment Fine surface refinement with smooth scratch patterns, ideal before polishing. Soft, Medium, Hard 120

  • What Are Magnetic Grinding Shoes?

    Magnetic grinding shoes are quick-change diamond tooling segments for floor grinders fitted with a magnetic plate system. Unlike bolted segments, they swap in seconds without tools - reducing downtime on site and keeping your crew moving between setups.

  • Choosing the Right Bond

    Matching bond hardness to your concrete is the single biggest factor in tool performance and life:

    • Soft bond (SSB / SB): Best for hard concrete and high-MPA surfaces
    • Medium bond (MB): Ideal for general-purpose grinding
    • Hard bond (HB): Suitable for soft or abrasive concrete

    Wrong bond = glazing, poor cut rate, and premature wear. When in doubt, start softer and adjust.

  • Grit Guide for Concrete Grinding

    Grit determines how aggressively the segment cuts and the scratch pattern it leaves:

    • 16 / 30 grit: Aggressive grinding and coating removal
    • 60 grit: Surface preparation and scratch removal
    • 120 grit: Fine grinding before polishing

    Always work coarse to fine - skipping grits costs time and finish quality.

  • Segment Types

    Magnetic grinding shoes come in different segment designs to suit various applications:

    • PCD tools: For aggressive coating removal (epoxy, glue, paint)
    • W segments: Fast cutting and efficient debris removal
    • Hexagon segments: Controlled grinding and smooth finish
    • Button segments: Fine surface refinement

    Choosing the right segment improves performance and finish quality.

  • Machine Compatibility

    Magnetic grinding shoes are designed for floor grinders equipped with a magnetic quick-change tooling plate, allowing operators to swap diamond tooling in seconds — no bolts, no tools, less downtime on site.

    Commonly used on Lavina 16X, 20N, 25G, and 30G series grinders, as well as EDCO Magna-Trap, Onfloor, Diamatic, and Blastrac and Vortex machines fitted with compatible magnetic systems.

    Compatibility depends on your grinder's tooling plate configuration. Not sure? Contact us before ordering and we'll point you in the right direction.

    Note: Husqvarna floor grinders use the Redi Lock system — see our Redi Lock Grinding Shoes for native-fit tooling.

Frequently Asked Questions

Can magnetic grinding shoes remove epoxy and glue?

Yes. Depending on the coating type and thickness, magnetic grinding shoes can be used for coating removal and surface preparation. For heavy epoxy, paint, glue, or waterproofing removal, PCD grinding shoes are often the most effective option.

What are magnetic grinding shoes?

Magnetic grinding shoes are quick-change diamond tooling segments used on floor grinders fitted with a magnetic plate system. They allow operators to change tooling in seconds without bolts or tools, reducing downtime and improving productivity on site. Magnetic grinding shoes are commonly used for concrete grinding, coating removal, and surface preparation.

What machines use magnetic grinding shoes?

Magnetic grinding shoes are compatible with many floor grinders fitted with magnetic quick-change tooling plates, including selected Lavina, EDCO Magna-Trap, Onfloor, Diamatic, Blastrac, and Vortex machines. Compatibility depends on your grinder's tooling plate configuration. If you're unsure, contact us before ordering and we'll help identify the correct tooling for your machine.

Which bond should I use?

Super soft and soft bonds suit hard, dense concrete with high MPa ratings. Medium bond is ideal for general-purpose grinding on mid-range concrete. Hard bond works best on soft, abrasive, or porous concrete. Using the wrong bond causes glazing and reduces tool life significantly.

What grit should I start with?

Start with 16 or 30 grit for aggressive grinding, coating removal, and heavy stock removal. Move to 60 grit for surface preparation and scratch refinement. Use 120 grit for fine grinding before polishing. For best results, always progress from coarse to finer grits.

What is the difference between magnetic and Redi Lock grinding shoes?

Magnetic grinding shoes use a magnetic quick-change plate system that allows tooling to be installed and removed without bolts or tools. Redi Lock grinding shoes use Husqvarna's proprietary quick-change locking system. Because the two systems use different mounting designs, they are not directly interchangeable without a compatible adaptor plate.

Do you ship magnetic grinding shoes internationally?

Yes, we ship worldwide from our Australian warehouse. For large or urgent international orders, contact us before ordering to confirm availability and freight options.

What is the difference between W shape, hexagon and button segments?

W segments are designed for aggressive grinding and fast debris removal, making them ideal for surface preparation. Hexagon segments provide controlled grinding with a consistent scratch pattern and smoother finish. Button segments are typically used for lighter grinding and surface refinement before polishing.
