PCD tools are used when the first job is removal, not polishing.
If the floor has epoxy, glue, mastic, waterproofing, old coating, or thick surface buildup, a standard metal bond diamond may not be the right first tool.
The goal is to remove the coating efficiently without wasting time loading up a grinding tool that was not designed for that first step.
For coating removal options, review our PCD and Coating Removal.
What PCD tools are used for
PCD tools are designed for aggressive coating removal and surface preparation.
They are commonly used before metal bond grinding when the floor still has material sitting on top of the concrete.
This can include epoxy coating, adhesive, glue, mastic, paint, waterproofing, or other jobsite residue.
After the coating is removed, the floor usually still needs grinding, scratch control, or preparation for the next system.
Do not choose PCD only by appearance
PCD tools can look similar in photos, but they are not all the same.
The buyer should confirm machine fitment, tooling system, rotation direction, floor condition, coating type, coating thickness, and the next job step.
A tool that works on one grinder system may not fit another machine.
A tool that works for one coating may be too aggressive or not aggressive enough for another coating.
If the machine system is unclear, confirm fitment before ordering.
Start with the coating type
The first question is what material needs to be removed.
Epoxy coating, glue, mastic, thin coating, thick coating, and waterproofing residue do not always behave the same way on the floor.
Some materials peel or chip away.
Some materials smear, soften, or load the tool.
Some materials require a more aggressive removal setup before the floor can be ground properly.
The coating type should guide the first tooling choice.
Check coating thickness and floor condition
A thin coating and a thick coating may need different removal behavior.
A soft or sticky coating can load the tool differently than a brittle coating.
A rough slab and a smooth slab can also change how the tool contacts the floor.
Before choosing PCD tools, check whether the coating is thin or thick, soft or brittle, patchy or continuous, and whether the concrete underneath is hard, soft, open, or closed.
Machine fitment is critical
PCD tools must match the grinder system.
Before ordering, confirm the machine brand and model.
Confirm the tooling plate or adapter system.
Confirm whether the tool needs a specific direction.
Confirm whether the product is made for your grinder interface.
For machine-specific tooling, review Shop by Machine.
Tool direction must be confirmed
PCD tools are often directional.
If the tool direction does not match the grinder rotation, removal performance can suffer.
The wrong direction can also affect tool life, floor contact, and jobsite results.
Do not assume direction from a product photo alone.
Before ordering, confirm grinder rotation direction and the correct PCD configuration for that machine.
PCD tools are not the final polishing step
PCD tools remove coating. They do not create the final floor finish.
After coating removal, the floor usually needs metal bond grinding to refine the surface and create the next scratch pattern.
This is where the workflow moves from removal into grinding.
For the next stage, review our Metal Bond Grinding Tools.
When metal bond tools are needed after PCD
After PCD removal, the floor may still show tool marks, rough surface areas, coating shadows, or uneven texture.
A metal bond grinding step helps level the floor, refine the surface, and prepare it for coating or polishing.
If the contractor wants to polish the floor, the process may continue from metal bond into hybrid pads and resin polishing pads.
For scratch refinement before resin, review Hybrid Pads.
Do not skip the test area
A small test area helps confirm whether the selected PCD setup is working correctly.
Check whether the coating is being removed cleanly.
Check whether the tool is loading.
Check whether the floor is being damaged more than expected.
Check whether the grinder feels stable.
Check whether the next metal bond step will be able to refine the surface.
What to send before ordering
Send the grinder brand and model.
Send the tooling system or plate type.
Send the coating type.
Send coating thickness if known.
Send floor photos and coating photos.
Send the current job step and target result.
Send the quantity and destination country.
These details help avoid ordering the wrong PCD tool for the machine or job condition.
Simple contractor takeaway
Use PCD tools when the first task is coating removal.
Use metal bond diamonds after removal when the floor needs grinding, leveling, or scratch control.
Use hybrid pads when metal scratches need to be reduced before resin polishing.
Do not choose PCD tools only from a photo.
Confirm machine fitment, tool direction, coating type, floor condition, and the next step before ordering.
Related Tools and Next Step
For epoxy, glue, mastic, and coating removal tools, review PCD and Coating Removal.
After coating removal, continue with Metal Bond Grinding Tools if the floor needs grinding, leveling, or scratch control.
If the metal step leaves visible scratches before polishing, check Hybrid Pads before moving into resin.
