Premium Redi Lock Diamond Grinding Shoes Compatible Double Bar
The ALSKAR DIAMOND Premium Redi Lock Diamond Grinding Shoes Compatible Double Bar are developed for professional flooring contractors, concrete grinding specialists, and surface preparation applications.
Designed around the Redi Lock-style quick-change mounting system, these grinding shoes feature two elongated metal-bonded diamond segments mounted on a red steel backing plate.
The two-segment arrangement helps distribute grinding contact across the working surface, making the Double Bar design a practical choice for general concrete floor grinding, surface leveling, and restoration.
Key Product Features
- Premium-grade diamond grinding tooling
- Two elongated diamond grinding segments with rounded ends
- Red steel backing plate and mounting-side finish
- Redi Lock-compatible quick-change connection
- Multiple diamond grit and bond hardness selections
- Designed for professional concrete floor grinding
- Flexible purchasing and packaging quantities
Progressive Concrete Grinding
The product range is planned around three diamond grit options:
- 18/20 Grit: Coarse grinding and initial surface preparation
- 30/40 Grit: General-purpose concrete grinding
- 60/80 Grit: Finer metal-bond grinding and surface refinement
Soft, Medium, and Hard bond choices allow users to match the diamond matrix to different concrete hardness conditions.
Professional Tooling for Compatible Grinders
These grinding shoes are intended for floor grinding machines equipped with matching Redi Lock tool holders.
Comparable products are commonly offered for selected Husqvarna PG floor grinders. Always confirm the actual mounting holder before ordering.
The ALSKAR Redi Lock Double Bar series is designed to provide a practical combination of mounting convenience, grit selection, and professional concrete grinding capability.
Double Bar Diamond Segment Design
The ALSKAR Redi Lock Compatible Grinding Shoe features two elongated metal-bonded diamond segments with rounded ends.
This design differs from conventional straight rectangular grinding bars and uses a distinctive rounded-end segment geometry.
Dual Diamond Grinding Segments
The two-segment arrangement distributes abrasive contact across the concrete surface.
When compared with a similar single-segment design, a Double Bar configuration generally offers a larger combined contact area and lower localized grinding pressure.
This makes it a practical choice for routine floor leveling, general concrete grinding, and consistent surface preparation.
Rounded-End Segment Geometry
Each grinding segment features elongated working surfaces with rounded or tapered ends.
The geometry provides a recognizable Double Bar design while maintaining two separate abrasive contact areas.
Metal-Bonded Diamond Construction
The diamond abrasive is retained within a metal-bond matrix.
During grinding, the metal matrix gradually wears to expose fresh abrasive diamond particles.
Grinding performance depends on the selected bond, diamond grit, segment design, concrete characteristics, and grinder operating conditions.
Open Segment Arrangement
The space between the two diamond segments allows grinding residue to move away from the active working areas.
Durable Red Steel Backing
The grinding segments are supported by a red steel backing plate.
The mounting side incorporates a raised connection profile intended for matching Redi Lock holders.
Application Advantages
- Distributed grinding contact
- General concrete floor leveling
- Surface grinding and restoration
- Progressive metal-bond grinding
- Convenient tooling replacement with a matching quick-change holder
Proper grit selection, bond matching, and mounting compatibility are essential for obtaining effective grinding results.
Diamond Grit Selection – 18/20, 30/40 & 60/80
Selecting the correct diamond grit helps control material removal, scratch depth, and the progression between grinding stages.
The ALSKAR Redi Lock Compatible Double Bar series is planned with three commonly used diamond grit ranges.
18/20 Grit – Coarse Grinding
18/20 grit is intended for the initial grinding stage when relatively aggressive concrete material removal is needed.
Typical Applications:
- Concrete high-spot removal
- Initial concrete floor leveling
- Rough surface preparation
- Grinding uneven cured concrete
- Preparing floors for subsequent grinding stages
30/40 Grit – General-Purpose Grinding
30/40 grit is a versatile selection for general concrete floor grinding and surface preparation.
Typical Applications:
- Routine concrete floor grinding
- Reducing marks left by coarse abrasives
- Surface leveling and restoration
- Commercial and industrial concrete preparation
- Intermediate grinding after coarse preparation
60/80 Grit – Finer Metal-Bond Grinding
60/80 grit is intended for surface refinement after coarse or general grinding.
Typical Applications:
- Reducing previous grinding scratches
- Intermediate concrete surface refinement
- Preparing floors for appropriate transitional polishing abrasives
- Progressive metal-bond grinding
- Smoothing cured concrete surfaces
Recommended Grinding Progression
A typical progression may be:
18/20 → 30/40 → 60/80
The correct grit sequence depends on the condition of the concrete, the selected bond, the machine, and the required final surface profile.
Not all projects require every grit stage.
Grinding Tip: Select the grit according to the grinding task and the bond hardness according to the concrete hardness and abrasiveness.
Soft, Medium & Hard Diamond Bond Selection
Diamond bond hardness determines how the metal-bond matrix wears during concrete grinding.
Selecting the correct bond is important for effective cutting action, diamond exposure, and tool service life.
As a general rule, the harder the concrete, the softer the recommended diamond bond. Softer or highly abrasive concrete generally requires a harder bond.
Soft Bond – Hard Concrete
Soft Bond tooling allows the metal matrix to wear more readily, helping expose new diamond cutting points when grinding hard concrete.
Typical Applications:
- Hard cured concrete
- Dense concrete floors
- Concrete that causes harder-bond tools to glaze
- Grinding applications requiring active diamond exposure
Medium Bond – Medium-Hard Concrete
Medium Bond is a general-purpose option for concrete with moderate hardness and abrasiveness.
Typical Applications:
- General concrete floor grinding
- Medium-hard concrete
- Commercial and industrial concrete surfaces
- Routine surface restoration and preparation
Hard Bond – Soft or Abrasive Concrete
Hard Bond tooling resists rapid matrix wear when grinding softer or more abrasive concrete.
Typical Applications:
- Soft cured concrete
- Highly abrasive concrete
- Floors causing excessive segment wear
- Applications requiring greater matrix wear resistance
Bond Selection Summary
| Concrete Condition | Recommended Bond |
|---|---|
| Hard Concrete | Soft |
| Medium-Hard Concrete | Medium |
| Soft / Abrasive Concrete | Hard |
Grinding Troubleshooting
If the segments glaze and cutting slows: Consider a softer bond or review the grinding conditions.
If the segments wear too quickly: Consider a harder bond.
If the grinding scratches are too coarse: Progress to a finer grit after completing the required material removal.
Concrete aggregate, grinding speed, equipment weight, and operating conditions may affect the optimal selection.
