EZ change HTC Double Button Grinding Segment For Concrete, Terrazzo Floor for HTC grinder Segment Size: 25*12mm – Metal Bond Customized
HTC double round grinding shoes are the go-to choice when you need a balance between aggressive material removal and a smooth, scratch-minimized finish. Because they have a rounded edge, they lack the sharp “leading edge” of a rectangular or arrow-shaped segment, which helps prevent deep gouging on uneven concrete.

HTC Double Button Grinding Segment are designed for Concrete, Terrazzo Floor Surface preparation.
Key Features & Benefits
• Reduced Scratching: The round shape “rolls” over the surface more smoothly than square segments, making them ideal for the transitional steps before you switch to resin polishing pads.
• Greater Surface Area: Compared to a single round shoe, the double round provides more contact points. This increases the tool’s lifespan and helps keep the machine stable on the floor.
• EZchange™ Compatibility: These are designed for the HTC “EZchange” system, allowing you to slide them into the tool holder and secure them with a rubber mallet—no screws or bolts required.
• High Head Pressure: While they have more surface area than a single segment, they still provide enough localized pressure to effectively cut through hard concrete caps.
Common Grit Ranges:
16/20 Grit: Heavy material removal, opening up the floor, or removing thin coatings (glue, epoxy).
30/40 Grit: Standard first step for grinding and leveling.
60/80 Grit: Honing step; removes the heavy scratches from previous stages.
120/150 Grit: Fine honing; used right before moving to resin-bonded polishing stages.
