Product Description
CMT 2-1/4" Coated Segment Saw Blade with Diamond Grit is a professional-grade oscillating multi-tool accessory designed for aggressive material removal in tile, marble, epoxy resin, grout, and masonry applications. Built with a 57mm diamond coated extra-long life segment, this blade delivers precise cutting and grinding performance where standard carbide blades fall short. The 25-piece pack offers exceptional value for contractors and tradespeople who rely on segment saw blades for high-volume grout removal, joint cutting, and duct sinking across a wide range of abrasive materials.
Key Features
- Diamond Grit Coating - provides extreme durability and longer service life compared to standard carbide grit, making it well-suited for tiles, marble, epoxy resins, and other abrasive surfaces that wear out conventional blades quickly.
- Universal Arbor (57mm) - fits most oscillating multi-cutters without adapters, reducing setup time and keeping the blade compatible across a wide range of tools on the job site.
- Efficient Segment Shape - allows aggressive grinding and material removal without damaging adjacent tile surfaces, giving the user greater control when working in tight or finished areas.
- Multi-Application Design - handles grout removal, marble and trass concrete joint cutting, duct sinking in plaster, brick, pumice, honeycomb stone, and autoclave aerated concrete, reducing the need to swap blades between tasks.
- 0.079" Tooth Thickness - a narrow kerf profile that concentrates cutting force for precise, controlled material removal in joint and grout lines.
- 25-Piece Pack - a high-quantity value pack that supports extended use on larger projects without frequent reordering.
Why This Product
- For professionals removing grout from tiled surfaces or cutting joints in marble and trass concrete, the diamond grit coating on this segment blade resists premature wear on abrasive materials - meaning fewer blade changes and more consistent results across the full length of a project.
- The universal arbor design combined with the blade's ability to sink ducts in plaster, brick, pumice, honeycomb stone, and autoclave aerated concrete makes this a single-blade solution for multiple masonry and tile tasks, reducing tool clutter and blade inventory on site.

Frequently Asked Questions
What types of oscillating multi-cutters does this blade fit?
This segment saw blade features a universal arbor design, which means it is compatible with most oscillating multi-cutter tools without requiring a separate adapter. Always confirm your tool's arbor compatibility before use.
Why is diamond grit preferred over carbide grit for tile and masonry work?
Diamond grit coating provides extra-long service life and maintains cutting performance on hard, abrasive materials such as tiles, marble, epoxy resins, porous concrete, and brick - surfaces that tend to wear carbide grit blades down much faster.
Can this blade be used for cutting as well as grinding?
Yes. The efficient segment shape is designed for aggressive grinding without damaging adjacent tile, and the blade is also suitable for cutting operations including marble joint cutting, trass concrete joint cutting, and sinking ducts in plaster, brick, pumice, honeycomb stone, and autoclave aerated concrete.
Is this blade suitable for grout removal without damaging surrounding tiles?
Yes. The segment design and diamond grit coating are specifically intended to remove tough grout from between tiled surfaces efficiently, and the blade's shape allows aggressive material removal while helping protect the tile face from incidental damage.
