15mm Jumbo Bar Segments Metal Bond — Precision Trapezoidal Diamond Tooling for Concrete Floor Grinding
The 15mm Jumbo Bar Segments Metal Bond are trapezoidal diamond grinding tools engineered for bolt-on floor grinding machines using the Trapezoid Quick Change system. Designed for concrete surface preparation, these double-bar segments measure 40×10×15mm and are available in three bond hardness options to match the full range of concrete hardness conditions encountered on the job. With five grit size options spanning coarse stock removal through fine finishing, contractors can select the exact combination of bond and grit required for each phase of a project. These segments are a professional-grade solution for flooring contractors, surface prep crews, and concrete polishing operations.

Unlike single-bar segments, the double-bar (jumbo) format provides a larger diamond contact area per tooling position, which translates to more consistent surface coverage on trapezoidal plate grinders. The three-bond system ensures the diamond matrix wears at the correct rate relative to the concrete hardness, preventing glazing on soft slabs or premature wear on hard surfaces. Contractors working across varied concrete conditions can stock all three bond types and select the appropriate segment rather than forcing a single tool to perform across incompatible substrates.
Key Features & Benefits
Three-Bond System for Concrete Hardness Matching
Soft, medium, and hard bond options allow contractors to match the segment's wear rate to the actual hardness of the concrete being ground. Using the correct bond prevents glazing and premature segment wear, extending tool life and maintaining consistent cut rate throughout the job.
Double Bar (Jumbo) Segment Format
The 40×10×15mm double-bar geometry delivers a larger diamond-bearing surface compared to single-bar segments. This increases the effective grinding contact area per tooling position, supporting more uniform material removal across the floor surface.
Five Grit Size Options
Available in 08/10, 16/20, 30/40, 60/80, and 120/150 grit, these segments cover the full range from aggressive coating removal and heavy stock removal through medium grinding and fine surface refinement. Contractors can progress through grit sequences using the same tooling platform without switching to a different segment system.
Trapezoid Quick Change Compatibility
Designed specifically for Trapezoid Quick Change bolt-on floor grinding machines, these segments install and swap quickly without specialized tooling. This reduces downtime between grit changes and bond changes on the job site.
Common Applications
Concrete Surface Preparation
Coarser grits (08/10, 16/20) are suited for initial surface preparation passes, removing laitance, light coatings, and surface irregularities from concrete floors prior to coating or polishing.
Coating and Adhesive Removal
Aggressive grit and bond combinations allow these segments to address residual adhesives and thin coatings on concrete substrates during floor renovation projects.
Concrete Grinding and Leveling
Mid-range grits (30/40, 60/80) are used for grinding down high spots, smoothing rough concrete, and achieving a consistent surface profile across large floor areas.
Concrete Polishing Progression
The 120/150 grit option supports the transition from grinding into the early stages of a concrete polishing sequence, refining the surface before moving to resin-bond tooling.
