Huanlong PCD grinding plates are used for fast removing all types of coatings such as paint, varnish, glue, epoxy, acrylic, screed residue, VCT mastic, black tar adhesive as well as thick rubber materials on the concrete floor.

This HTC grinding shoe features two quarter-round PCDs for aggressive removal of coatings, adhesives, epoxy, paint, and other surface materials from concrete floors. Two additional square steel bases are used to weld the PCDs, increasing the tool’s strength and ensuring stable grinding performance. Original high-quality PCDs are used to ensure fast and efficient stripping without gumming up or clogging.

WerkMaster PCD (Polycrystalline Diamond) Tools are the ultimate solution for tackling tough coating removal jobs on concrete surfaces, especially when dealing with layers 1-3mm in thickness. These innovative tools feature industrial-grade PCD abrasives that make light work of even the most stubborn coatings, including epoxies, urethanes, and mastics.
STI diamond grinding pucks are specialized metal bond grinding tools used with Substrate Technology (STI) Prep/Master grinders for concrete surface prep, featuring diamond segments (often 10) in various bonds (hard, medium, soft) and grits (like 16/20, 60/80, 120/150) to aggressively grind, level, or remove coatings from concrete floors, utilizing quick-change systems for easy tool swaps.

High Quality Sti Grinding Removal Tools Features:
1.Compatibility: Designed for STI Prep/Master grinders, often using quick-change or magnetic systems (like Fast Change, Polar Magnetic) for easy attachment.
2.Bond Types:
Hard Bond: For soft concrete to prevent excessive wear.
Soft Bond: For hard concrete to expose diamond segments.
Medium Bond: General purpose, good for various concrete hardnesses.
3.Grit & Application: Coarser grits (16/20) for aggressive coating/adhesive removal, finer grits (120/150) for smoother grinding or finishing.
Segments: Typically feature multiple diamond segments (e.g., 10) in various shapes (trapezoid, round) for efficient grinding.
How They Work:
They attach to the grinder’s plate, often via pins or magnetic systems.
The diamond segments cut into the concrete surface as the machine rotates.
Choosing the right bond (hard/soft) and grit (coarse/fine) is crucial for matching the tool to the concrete’s hardness and the desired outcome (e.g., removal vs. smoothing).
