Redi-Lock with Two Full PCDs and One Cylinder Metal Bond is a heavy-duty, hybrid tool optimized for the rapid removal of thick, stubborn coatings while maintaining strict control over the grinding depth. In this setup, the “cylinder” acts as a high-durability stabilizer that is more robust than a standard flat bar or button.

SASE double button grinding shoes used with concrete floor grinders, they are specifically designed to fit SASE and other compatible floor grinding machines for concrete surface preparation and polishing
The PCD tool uses a scraping action, making it very suitable for removing pressure-sensitive coatings, adhesives, and waterproof materials with a thickness exceeding 3 millimeters. Traditional diamond cup wheels may become clogged or overheated by these materials.
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.

1. When to Use Single Bar Shoes
• Hard Concrete: If you are struggling to “open up” a very hard, high-PSI concrete floor, single bars provide the downward pressure needed to keep the diamonds from glazing over.
• Lightweight Grinders: On smaller or single-phase machines that lack the head weight of a large industrial grinder, single bars ensure the tool actually engages with the surface rather than just skating over it.
• Thin Coating Removal: They are excellent for “scarifying” or removing thin layers of paint, glue, or epoxy because they “plow” through the material more effectively than a flat double-bar.
• Exposing Aggregate: If the goal is a “salt and pepper” or large aggregate look, the single bar will cut through the cream layer much faster.
2. Choosing the Right Bond
To get the most out of your HTC tooling, you must match the metal bond to the hardness of your concrete (measured by a Mohs scratch test):
• Soft Bond: Use on Hard concrete. The bond wears away quickly to reveal fresh diamonds.
• Medium Bond: Use on Medium hardness concrete.
• Hard Bond: Use on Soft/Abrasive concrete. A hard bond prevents the abrasive concrete from eating through your segment too quickly.
