HTC single bar grinding shoes are more aggressive compared to their double-segment plate. Because the machine’s entire weight is concentrated on half the surface area (one bar instead of two), they bite significantly deeper into the concrete and best for lighter machines.
Huanlong3 Parallel Rectangle segments Redilock grinding shoes are specifically designed for high-efficiency floor prep and aggressive coating removal.
Huanlong Aluminium Turbo Diamond grinding cup wheel, For fast and smooth grinding material such as concrete, Terrazzo, Engineered Stone, granit, marble or other nature stone, etc.
PHX floor concrete diamond grinding double rectangular bar segment shoe plate tools are metal-bond diamond abrasive plates designed for aggressive grinding and leveling of concrete and terrazzo floors, specifically compatible with PHX floor grinding machines. They are available in various bonds (soft, medium, hard) and grit sizes to suit different concrete hardnesses.
Double Quarter Round PCD With 1 Segment Best Use For Epoxies, acrylics, paints, and thicker glues/mastics. Ideal for 1mm to 2mm thick coatings. Works well on both small single-head (PG 280) and medium planetary (PG 450/530) machines.

The Redi-Lock with 2×1/4 PCD & 1 Bar Segment is the go-to tool for removing medium-thick coatings where you want to balance speed with a controlled finish.
Compare to the 3X1/4 PCD, this 2-PCD version is slightly more aggressive because the machine’s weight is concentrated on two points instead of three.
This Redilock PCD Shoes With only two 1/4 chips, each chip bites deeper into the coating. This makes it better than the 3-PCD version for slightly thicker or tougher materials that a 3-PCD might “skate” over. It removes material slightly faster in most conditions because the chips are less likely to get “clogged” with debris, as there is more open space on the tool face.
The Stabilizing Bar limits how deep the two PCD chips can dive. Without this bar, the 2×1/4 PCDs would likely “trench” the floor or chatter violently.
The bar is usually a coarse metal-bond diamond (around 20-30 grit). It grinds the floor while the PCDs scrape, which helps “clean up” the aggressive gouges and prepares the concrete for the next step of metal bonds.
