Lavina 2x 1/4 PCD refers to a specific type of diamond grinding tool, a PCD (Polycrystalline Diamond) shoe/segment, designed for aggressive concrete surface preparation, particularly for stripping thick coatings like epoxy, paint, glue, and mastic, compatible with Lavina grinders and other systems like EDCO and Onfloor.
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.
Diamond grinding plugs with arrow segments are aggressive, specialized removal tooling for floor grinders, featuring an arrow-shaped cutting edge to rapidly remove thick glues, epoxy, mastic, and other tough coatings from concrete, offering fast stock removal, reduced gumming, and efficient preparation for polishing or resurfacing
Three M9 holes Double arrow grinding shoes are metal-bonded diamond grinding tools specially designed for Iron Horse, ASL, Xingyi and Wolfpack Grinder. They have two arrow-shaped diamond segments, which are used for efficient grinding of concrete, terrazzo, and removing coatings and adhesives.
This is a highly specialized, heavy-duty floor preparation tool designed for concrete grinders, particularly those compatible with SASE brand mounting systems. The tooling configuration, which includes 2 PCD segments plus 1 carbide segment, is engineered to balance extreme aggressiveness (for stripping) with stability (to protect the floor).

Sase Aggressive 2 half-round PCD diamond segment and 1 Button Segment
• 2 X 1/2 PCD Segments (Polycrystalline Diamond):
• Function: These serve as the primary ‘teeth.’ PCD is a synthetic diamond material known for its extreme hardness and sharpness.
• Shape: The half-round design offers a large, durable cutting edge. Unlike smaller 1/4-round segments, this shape allows them to plow through thick, sticky, or rubbery coatings without breaking.
• Aggressiveness: Very high. Instead of grinding the surface, they scrape and tear coatings off concrete.
• 1 Button Segment (The ‘Stabilizer’ ):
• Function: This is a Button, rectangular or arrow-shaped bar made of tungsten carbide or a metal-bond diamond matrix.
• Purpose: Using only PCDs could cause excessive digging into the concrete substrate, leading to damage to both the concrete and the machine. The carbide segment sits slightly lower or flush with the PCDs, acting as a depth gauge. It prevents the PCDs from cutting too deeply and helps smooth the rough surface left by their ripping action.
This tool specializes in coating removal and is not intended for general concrete grinding or polishing. Its applications include:
• Thick Epoxies & Urethanes: Removing industrial coatings that would quickly clog (glaze over) standard diamond abrasives.
• Sticky Materials: Eliminating mastic, carpet glue, VCT glue, and rubberized elastomers.
• Thick Paints & Sealers: Stripping parking deck coatings or waterproofing membranes.
