Overview

These metal bond diamond grinding shoes are designed for Schwamborn grinders with knock-on style tool holders. They are suitable for concrete grinding, floor leveling, surface preparation, and removal of thin coatings or surface contaminants before the next step.

With multiple grit and bond options, you can match the tool to the slab hardness and the stage of the job — from aggressive opening cuts to smoother preparation before finer grinding or polishing.

Best for

• Concrete floor grinding and leveling

• Surface preparation before coatings or polishing

• Scratch pattern refinement before finer steps

• Removal of thin surface residue and weak coatings

• Professional use with Schwamborn-compatible knock-on systems

Features

• Grit options: 6#, 16#, 30#, 60#, 120#

• Bond options: Soft, Medium, Hard

• Soft bond for hard concrete

• Medium bond for general-purpose jobs

• Hard bond for soft or abrasive concrete

• Knock-on style mounting for fast tool changes

• Durable metal bond matrix for stable cutting and consistent wear

• Suitable for wet or dry grinding, depending on site conditions

Fitment Note

Designed for Schwamborn-compatible knock-on tool holder systems. Please check your machine plate and holder style before ordering. If you are unsure, send us a photo of your plate or current tool, and we can help confirm fitment.

FAQ

What are these metal bond shoes mainly used for?

They are mainly used for concrete grinding, leveling, and surface preparation. They are also suitable for removing thin surface residue or weak coatings, but for heavy epoxy, thick glue, or thick mastic removal, PCD tools are usually the better choice.

How do I choose the right bond hardness?

• Soft bond: best for hard concrete

• Medium bond: good general-purpose choice for average concrete

• Hard bond: best for soft or abrasive concrete

Which grit should I start with?

• 6# or 16#: aggressive opening cut and heavy stock removal

• 30#: common first grinding step for many floors

• 60#: smoother grinding and scratch reduction

• 120#: finer surface preparation before the next stage

Can they be used wet or dry?

Yes. Both wet and dry use are possible. Wet grinding can help with dust control and tool life in some applications, while dry grinding is often preferred for easier jobsite cleanup and vacuum use.

Are they compatible with all Schwamborn models?

They are made for Schwamborn-compatible knock-on systems. Because holder styles can vary by machine setup or plate configuration, fitment should be confirmed before ordering.

What should I use after these grinding shoes?

That depends on your floor condition and target finish. In many cases, the next step is a finer metal bond grit, then transitional pads or resin polishing pads if polishing is required.
