Overview

This QC concrete diamond grinding tool shoe puck is designed for concrete floor grinding and surface preparation with Lavina / EDCO style workflows. It is used for slab opening, scratch control, leveling, and heavy grinding before transition or polishing steps.

The page description also references ASL, Bartell, Dr. Shultz, Iron Horse, Virginia, and Xingyi grinder use. Because holder systems can vary by machine and plate setup, fitment should be confirmed before ordering.

For more machine-based tooling options, check Lavina grinder tools, EDCO grinder tools, or Shop by Machine.

Grit and Bond Guide

Use 6 grit for very aggressive opening cuts and heavy first-step grinding.

Use 16 grit for aggressive grinding, surface opening, and scratch correction.

Use 30 grit for common concrete grinding and surface preparation.

Use 60 grit for moderate grinding and scratch refinement.

Use 120 grit for smoothing and scratch reduction before moving into finer transition or polishing steps.

For hard concrete, choose a softer bond to keep diamonds exposed. For softer or more abrasive concrete, choose a harder bond to help control tool wear.

Fitment Note

This product is positioned for Lavina / EDCO style grinding workflows, with additional machine references listed on the product page. Before ordering, confirm your machine brand, model, holder style, required grit, bond selection, and quantity.

Do not order by machine brand name alone. Confirm that your current holder or plate system accepts this QC grinding shoe puck.

If fitment is unclear, check Lavina grinder tools, EDCO grinder tools, review adapters and plates, or send your machine model and holder photo through Contact Us.

Grinding Workflow

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

Use this QC diamond grinding shoe puck for concrete opening, leveling, scratch control, and surface preparation.

After metal grinding, use hybrid pads to refine visible metal scratches before final polishing with resin polishing pads.

For broader metal grinding options, browse metal bond grinding tools.

Shipping

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

FAQ

Q1: What is this QC concrete grinding shoe puck mainly used for?
It is mainly used for concrete floor grinding, surface preparation, slab opening, scratch control, and heavy grinding before transition or polishing steps.

Q2: Which grit should I choose?
Choose the grit according to the grinding stage and scratch depth. Lower grits are more aggressive, while higher grits are used for scratch refinement before transition or polishing steps.

Q3: Which bond should I choose?
Choose the bond according to concrete hardness. Softer bonds are used for hard concrete, while harder bonds are used for softer or more abrasive concrete.

Q4: Is this tool for coating removal?
It is a metal bond grinding tool, not a primary PCD coating removal tool. If the floor has epoxy, glue, paint, mastic, or coating residue, use PCD coating removal tools first.

Q5: Does it fit every Lavina or EDCO grinder?
No. Fitment depends on the machine model, holder system, plate setup, and tool interface. Confirm compatibility before ordering.

Q6: What should I send before ordering?
Send your machine brand and model, holder or plate photo, concrete hardness if known, current floor condition, required grit, bond selection, target finish, and quantity.
