Reclaiming the Foundation
Imagine standing on an industrial floor buried under years of thick, stubborn epoxy and failed coatings. Traditionally, removing this "skin" would mean hours of frustration—watching standard diamond tools glaze over, heat up, and eventually fail. When you hold our New Half Round Grinding Disc, you feel the cold, heavy industrial steel body and the sharp, jagged edge of the PCD segments—a tool that doesn't just grind, it conquers. As you engage the machine, the sound changes from a dull scrape to a powerful, rhythmic "crunch" as the PCD segments bite through the coating and reach the raw concrete beneath.
The true beauty of this tool lies in the tactile feedback it provides through the grinder's handle. You feel the machine gliding more smoothly as the half-round segments clear away debris instead of riding over it. There is no suffocating smell of burning resin because the disc slices the material away in clean chips. This disc was inspired by the need for a "one-pass" solution in floor restoration. Whether you are preparing a massive warehouse for a new finish or stripping a residential garage floor, this disc transforms a grueling labor-intensive task into a fast, satisfying process. It restores not just the floor, but your schedule and your bottom line.
Product Features and Highlights
Aggressive PCD Slicing Action
Unlike traditional diamond segments that rely on friction to wear down a surface, our PCD segments act like a series of lathes. They penetrate the coating and peel it away from the concrete substrate. This prevents the "smearing" effect often seen when trying to remove sticky materials with standard metal-bond diamonds.
No Glazing: The PCD edges stay sharp and exposed, even when facing high-build coatings.
Reduced Friction: Minimal surface contact reduces heat, preventing adhesives from becoming gummy.
Precision Engineered Half-Round Geometry
The unique semi-circle shape is a result of extensive field testing. This geometry ensures that the leading edge of the segment is always engaging the material at the optimal angle. It provides a larger "sweeping" path than traditional square segments, which means fewer passes and a more uniform surface profile.
Durability in Extreme Environments
Floor preparation is a brutal environment. Our discs are constructed from high-tensile steel that has been vacuum-brazed to ensure the PCD segments never shear off under high torque. This tool is built for the "contractor grade" lifestyle—meaning it stays in the job box for months, not days.
Vibration Dampening: The mass of the disc helps absorb micro-vibrations, protecting the motor of your expensive floor grinder.
Longevity: One set of Half Round PCDs can often outlast five sets of standard grinding shoes.
Advanced PCD Technology & Surface Mastery
The secret to our Surface Preparation Mastery lies in the molecular structure of the PCD. Polycrystalline Diamond is created by sintering together diamond particles under ultra-high pressure and temperature. The result is a segment that possesses the hardness of a diamond but the toughness of a structural alloy. In our New Half Round series, we have strategically placed these segments to ensure they "scrape" the substrate at a specific shear angle.
This engineering choice is critical when dealing with "elastic" coatings like polyurethane or rubberized membranes. A standard diamond disc would simply slide over these materials. Our Half Round PCDs catch the edge of the membrane and lift it. By combining these PCDs with a sacrificial metal bond segment, the tool simultaneously removes the coating and begins the initial scratch pattern on the concrete. This dual-action approach saves the operator an entire stage in the floor polishing process, representing a massive leap in operational efficiency.
Industrial Application Scenarios
Our customers rely on this disc for the "impossible" jobs—the ones where other tools have failed. It is the go-to choice for large-scale demolition and renovation projects across various sectors.
Warehouse Floor Renovations: Rapidly removing miles of old warehouse aisle markings and epoxy coatings.
Retail Space Preparation: Stripping away thick black mastic and carpet glue to reveal a polishable concrete surface.
Commercial Kitchens: Removing grease-saturated urethane mortars that have become extremely hard over time.
Industrial Parking Garages: Leveling high spots and removing weather-proof membranes in one high-speed operation.
Hazardous Material Abatement: Efficiently removing coatings in a controlled manner, producing larger chips that are easier to vacuum and manage than fine dust.

Cost-Per-Square-Foot Efficiency: We focus on the "total cost." By lasting longer and cutting faster, our discs significantly reduce your labor costs and abrasive consumption.
Specialized Technical Support: Our team consists of former floor technicians who understand the chemistry of coatings and the physics of grinding. We help you choose the right tool for the right bond.
FAQ (Frequently Asked Questions)
Q: Why should I use a PCD disc instead of a high-grit diamond disc?
A: Diamond discs work by grinding and are best for smoothing concrete. PCD (Polycrystalline Diamond) discs work by scraping and slicing. If you are trying to remove a coating (like epoxy or glue), a diamond disc will likely heat up and smear the material. A PCD disc will slice it off cleanly.
Q: Do I need a specific rotation direction (Clockwise vs. Counter-Clockwise)?
A: Yes. For machines like the Scanmaskin, the direction of the segment is vital for efficiency. Our Half Round discs are clearly marked. Using the wrong direction will result in poor performance and premature wear of the steel carrier.
Q: Can these discs be used on very soft concrete?
A: While they can, you must be careful. PCDs are very aggressive and can "gouge" soft concrete if too much pressure is applied. We recommend using them with a lighter touch or on machines with variable speed controls when working on soft substrates.
Q: What should I do if the PCD segments encounter metal bolts in the floor?
A: Our vacuum-brazed segments are incredibly tough, but hitting large metal objects at high speed is never ideal. If you encounter a bolt, the PCD will likely cut through it, but it may cause micro-chipping. We recommend a visual inspection of the floor before starting the grind.
