Overview

3-hole trapezoid double bar metal bond diamond grinding shoes for ASL and Xingyi floor grinder systems. The double bar segment design provides stable grinding contact for concrete floor grinding, leveling, surface preparation, and scratch reduction.

Use this tool during the metal grinding stage after coating removal or when the concrete surface is ready for slab opening, profiling, or controlled scratch refinement. Choose the grit and bond according to concrete hardness, floor condition, grinding stage, and target finish.

Best For

• Concrete floor grinding
• Surface preparation before polishing
• Floor leveling and scratch reduction
• General metal-stage grinding workflows
• ASL / Xingyi style 3-hole trapezoid holder systems

Features

• 3-hole trapezoid mounting style
• Double bar metal bond segment design
• Stable grinding contact for general concrete prep
• Multiple grit options for different grinding stages
• Soft, medium, and hard bond options for different concrete conditions
• Suitable before hybrid transition or resin polishing stages

Available Grits

6 / 16 / 30 / 60 / 120

Use 6 or 16 grit for aggressive opening and heavier removal. Use 30 or 60 grit for general grinding and scratch control. Use 120 grit when the floor needs finer scratch refinement before transition or polishing.

Available Bond Types

Soft Bond – for hard concrete
Medium Bond – for general concrete
Hard Bond – for soft or abrasive concrete

If the concrete hardness is unclear, test a small area first or send the jobsite details before ordering.

Fitment Note

This product is designed for ASL / Xingyi style 3-hole trapezoid holder systems. Fitment should be confirmed before ordering.

Some grinder systems may use similar 3-hole trapezoid tooling, but compatibility should not be assumed without checking the plate and mounting pattern.

Before ordering, confirm:

• Grinder brand and model
• 3-hole plate or holder style
• Hole spacing and mounting pattern
• Required grit and bond
• Quantity needed for the full machine set
• Current floor condition and target result

If the holder or plate interface is unclear, check adapters and plates or send machine and plate photos through Contact Us.

Polishing Workflow

If the floor still has epoxy, glue, paint, mastic, or coating residue, start with PCD coating removal tools before using metal bond grinding tools.

After metal grinding, use hybrid pads if visible metal scratches need refinement before final polishing.

For the final polishing stage, continue with resin polishing pads after the scratch pattern is controlled.

Shipping

Order processing and delivery time depend on stock status, order quantity, destination country, and shipping method. If you have a deadline, send the required delivery date before ordering.
