Premium HTC EZchange Diamond Grinding Shoes Compatible Double Bar
The ALSKAR DIAMOND Premium HTC EZchange Diamond Grinding Shoes Compatible Double Bar are developed for professional concrete grinding contractors, flooring specialists, and surface preparation applications.
Each grinding shoe features two straight rectangular metal-bonded diamond segments mounted on a black steel backing plate.
The Double Bar design distributes grinding contact across two diamond segments, making it a practical choice for general concrete grinding, surface leveling, and progressive floor preparation.
Designed for HTC EZchange Tool Holders
The backing plate incorporates a side-wing quick-change connection intended for use with compatible HTC EZchange-style holders.
This connection differs from conventional bolt-on grinding shoes and Redi Lock tooling.
Correct holder identification is essential before installing replacement grinding tools.
Premium Metal-Bonded Diamond Construction
The diamond segments are manufactured using metal-bonded diamond abrasive technology.
As the metal matrix wears during grinding, fresh diamond particles are progressively exposed to continue the cutting process.
Nine Grit and Bond Configurations
The series is available in three diamond grit ranges:
- 18/20 Grit: Coarse concrete grinding
- 30/40 Grit: General-purpose grinding
- 60/80 Grit: Finer metal-bond surface preparation
Each grit is offered in Soft, Medium, and Hard bond options to accommodate different concrete conditions.
Professional Applications
Suitable for cured concrete floor leveling, restoration, and preparation before subsequent grinding, polishing, or coating applications.
Actual grinding results depend on the concrete substrate, selected grit and bond, grinder characteristics, and operating conditions.
Double Bar Diamond Segment Design for Consistent Concrete Grinding
The ALSKAR HTC EZchange Compatible Grinding Shoe features two straight rectangular metal-bonded diamond segments attached to a black steel backing plate.
Dual Diamond Grinding Segments
Two separate diamond grinding segments distribute abrasive contact across the working area.
Compared with an otherwise similar single-segment design, a Double Bar configuration generally offers a larger combined grinding contact area.
This makes it suitable for many general-purpose concrete floor grinding and leveling applications.
Straight Rectangular Segment Geometry
The two rectangular diamond segments are positioned at different angles on the backing plate.
The layout provides two distinct grinding contact areas for professional concrete surface preparation.
Premium Metal-Bonded Diamond
Industrial diamond abrasive particles are held within a metal-bond matrix.
The gradual wear of the matrix exposes new diamond cutting points during operation.
Grinding performance and segment wear depend on the bond hardness, diamond grit, concrete abrasiveness, and machine operating conditions.
Open Grinding Layout
The space between the two grinding bars allows grinding residue to move away from the active contact areas.
Durable Black Steel Backing
The steel backing supports the diamond segments and incorporates side-wing mounting features for a matching quick-change tool holder.
Product Highlights
- Two straight rectangular diamond grinding segments
- Premium metal-bonded diamond construction
- Distributed abrasive contact
- Black steel backing plate
- HTC EZchange-compatible mounting
- Nine grit and bond configurations
The design is intended for concrete floor grinding, surface leveling, and progressive surface preparation.
Diamond Grit Selection Guide – 18/20, 30/40 & 60/80
Selecting the correct diamond grit helps control grinding aggressiveness, scratch depth, and the progression between concrete preparation stages.
ALSKAR Premium HTC EZchange Compatible Double Bar Grinding Shoes are available in three grit ranges.
18/20 Grit – Coarse Concrete Grinding
18/20 grit is intended for initial grinding where relatively aggressive material removal is required.
Typical Applications:
- Initial concrete floor grinding
- Concrete high-spot removal
- Coarse surface leveling
- Preparation of uneven cured concrete
- Starting stages of floor restoration
30/40 Grit – General-Purpose Concrete Grinding
30/40 grit is a versatile selection for regular concrete grinding and surface preparation.
Typical Applications:
- General concrete floor grinding
- Reducing coarse grinding marks
- Routine surface leveling
- Concrete floor restoration
- Preparation for subsequent finer grinding
60/80 Grit – Finer Metal-Bond Surface Refinement
60/80 grit is intended for additional surface refinement after coarse or general grinding.
Typical Applications:
- Reducing scratches from previous grinding stages
- Intermediate metal-bond grinding
- Smoothing cured concrete
- Preparation before compatible hybrid or resin-bond polishing stages
Recommended Grinding Progression
A common progression is:
18/20 → 30/40 → 60/80
The appropriate starting grit and number of steps depend on the concrete condition, required surface profile, and final finishing system.
Not every floor requires all three grit stages.
Selection Tip: Choose grit according to the grinding stage and bond hardness according to the concrete’s hardness and abrasiveness.
Soft, Medium & Hard Diamond Bond Selection
Selecting the appropriate bond hardness helps maintain efficient grinding action and suitable diamond segment wear.
In metal-bonded diamond tooling, the bond matrix gradually wears to expose fresh abrasive particles.
As a general guideline, hard concrete typically requires a softer bond, while soft or highly abrasive concrete generally requires a harder bond.
Soft Bond – Hard Concrete
Soft Bond tooling is designed to expose fresh diamond abrasive more readily when grinding hard or dense concrete.
Typical Conditions:
- Hard cured concrete
- Dense concrete floors
- Concrete that causes harder-bond tooling to glaze
Medium Bond – Medium-Hard Concrete
Medium Bond is a versatile option for concrete with moderate hardness and abrasiveness.
Typical Conditions:
- General-purpose concrete grinding
- Medium-hard concrete
- Commercial and industrial floor preparation
- Routine surface restoration
Hard Bond – Soft or Abrasive Concrete
Hard Bond tooling helps resist rapid matrix wear when working on softer or highly abrasive concrete.
Typical Conditions:
- Soft cured concrete
- Abrasive concrete surfaces
- Floors that cause excessive diamond segment wear
Bond Selection Summary
| Concrete Condition | Recommended Bond |
|---|---|
| Hard Concrete | Soft Bond |
| Medium-Hard Concrete | Medium Bond |
| Soft / Abrasive Concrete | Hard Bond |
Troubleshooting
Tool glazing or poor cutting: A softer bond may improve diamond exposure.
Excessive segment wear: A harder bond may help reduce premature matrix wear.
Grinding scratches too coarse: Move to an appropriate finer grit after the required material removal is complete.
Concrete aggregate, grinder weight, grinding speed, and surface condition also affect the best bond selection.
