  • What Are Redi Lock Grinding Shoes?

    Redi Lock segments are natively compatible with Husqvarna floor grinders and can also be used on HTC, Vortex, Satellite, Terrco, and other floor grinding machines with a compatible adaptor plate. Available in a range of segment shapes, bond hardnesses, and grit sizes — matched to your concrete type and application for maximum performance and tool life.

  • Choosing the Right Bond

    Getting the bond wrong is the most common mistake in concrete grinding. Match your bond to your concrete hardness:

    Super Soft bond (SSB ): Best for hard concrete and high-MPA surfaces.

    Soft Bond (SB): Hard concrete
    Medium bond (MB): Ideal for general-purpose grinding
    Hard bond (HB): Suitable for soft or abrasive concrete
    Super Hard (SHB):Very soft or highly abrasive concrete surfaces

    Using the correct bond helps maintain cutting performance, reduces glazing, and extends tool life.

  • Grit Guide for Concrete Grinding

    16 grit: Aggressive grinding, coatingand glue removal

    30 grit: Coating, glue, and adhesive removal
    60 grit: Surface preparation and scratch refinement
    120 grit: Fine grinding before polishing

    For best results, start coarse and work your way up.

    For heavy coatings or epoxy, it is recommended to start with PCD diamond tools before switching to coarse grit redi lock grinding shoes.

Frequently Asked Questions

What are Redi Lock grinding shoes?

Redi Lock grinding shoes are quick-change diamond tools used on floor grinders for concrete grinding, coating removal, and surface preparation. They are widely used with Husqvarna and compatible machines.

Which bond should I use for concrete grinding?

Soft bonds are best for hard concrete, while hard bonds are used for softer or abrasive surfaces. Choosing the correct bond helps prevent glazing and improves grinding performance.

What machines are compatible with Redi Lock grinding shoes?

Redi Lock grinding shoes are designed for Husqvarna floor grinders and can also be used with adaptor plates for other machines such as HTC, Vortex, Satellite, and Terrco.

When should I use PCD grinding tools?

PCD tools are used for aggressive removal of coatings such as epoxy, glue, and paint. They are typically used before switching to standard grinding segments.

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

Redi Lock grinding shoes use Husqvarna's quick-change locking system, while magnetic grinding shoes attach to magnetic adaptor plates. Both allow fast tool changes, but compatibility depends on your grinder and tooling setup. Contractors often use converter plates to run magnetic shoes on non-magnetic machines.

How many grinding shoes do I need per grinder head?

Most floor grinders require one grinding shoe per tooling position. For example, a three-head grinder typically uses nine grinding shoes, while larger planetary grinders may use eighteen or more. Always refer to your machine manufacturer's recommendations.

What grit should I start with for concrete grinding?

The starting grit depends on the condition of the floor and the amount of material that needs to be removed. 16 grit is commonly used for aggressive grinding and coating removal, 30 grit for general surface preparation, 60 grit for scratch refinement, and 120 grit for fine grinding before polishing.

How long do Redi Lock grinding shoes last?

Tool life depends on the concrete hardness, bond selection, grinder weight, and operating conditions. Using the correct bond for the concrete is the most important factor in maximising grinding performance and extending tool life.

Do you offer bulk or wholesale pricing on Redi Lock segments?

Yes. Paddle Wholesale Australia supplies Redi Lock grinding shoes to contractors, flooring specialists, and equipment hire companies. Trade and bulk pricing may be available depending on quantities and product selection.

What segment shape should I choose for concrete grinding?

Different segment shapes are designed for different grinding applications. Arrow segments provide aggressive cutting action and fast material removal, making them ideal for opening concrete, removing high spots, and heavy surface preparation. Star segments offer a similar aggressive cutting action to arrow segments, but with the added advantage that they can run in both directions, unlike directional arrow segments. Rectangle segments are a versatile choice for general concrete grinding and surface preparation. Hexagon segments provide controlled grinding and efficient debris removal, while button segments are commonly used for finer grinding and surface refinement. PCD tools are designed specifically for aggressive removal of coatings such as epoxy, glue, paint, and other surface contaminants.
