Product Description
The CMT 2-1/4" Coated Segment Saw Blade with Diamond Grit by CMT is an oscillating multi-tool accessory engineered for demanding cutting, grinding, and grout removal tasks across a wide range of hard and abrasive materials. Featuring an extra-long life diamond grit coating and a universal 57mm arbor, this segment blade delivers aggressive material removal on tiles, marble, epoxy resins, plaster, brick, pumice, and autoclave aerated concrete - all without damaging surrounding surfaces. Whether you are cutting out marble joints, sinking ducts in masonry, or clearing tough grout from tiled surfaces, this blade offers the precision and durability that professional tradespeople require. Sold as a single piece.
Key Features
- Diamond grit coated segment design - provides extreme cutting performance and extra-long service life compared to standard carbide grit blades, making it especially effective on tiles, porous concrete, brick, and other abrasive materials.
- Universal 57mm arbor compatibility - fits most oscillating multi-cutters, so you can put this blade to work immediately without adapters or additional hardware.
- Efficient segment shape - allows aggressive grinding and material removal while protecting adjacent tile surfaces from damage, ideal for precise grout removal and joint cutting.
- 0.079" tooth thickness - delivers a controlled, consistent kerf for clean cuts in marble joints, trass concrete joints, cement joints, and epoxy resin surfaces.
- Broad material compatibility - cuts and grinds tiles, marble, epoxy resins, plaster, brick, pumice, honeycomb stone, and autoclave aerated concrete, reducing the need for multiple specialty blades on a single job.
- Multi-directional cutting surface - the grit-coated face enables free-hand routing, shaping, and grinding in multiple directions, giving you greater flexibility in tight or irregular spaces.
Why This Product
- Built for grout and joint work without tile damage - the efficient segment geometry is specifically designed to remove tough grout from between tiled surfaces aggressively while leaving the tile face intact, a critical requirement for renovation and repair work.
- One blade, many masonry applications - from sinking ducts in plaster and brick to cutting marble joints and epoxy resin surfaces, this single diamond segment blade replaces several single-purpose accessories, simplifying your tool kit.
- Diamond grit outperforms carbide grit on hard and abrasive surfaces - the coated segment construction is rated for extra-long life specifically on the hardest and most abrasive materials, meaning fewer blade changes and lower cost per job.
- Universal arbor means broad machine compatibility - the 57mm universal arbor interface works with most oscillating multi-cutter brands, so you are not locked into a single tool ecosystem.

Frequently Asked Questions
What types of materials can this diamond segment blade cut or grind?
This blade is designed for tiles, marble, epoxy resins, plaster, brick, pumice, honeycomb stone, and autoclave aerated concrete. It is also effective for removing grout from between tiled surfaces and for cutting marble and trass concrete joints.
Will this blade damage the tile when removing grout?
The segment saw blade features an efficient shape specifically designed to allow aggressive grinding along grout lines without damaging the adjacent tile surface, making it well suited for renovation and repair projects.
What oscillating multi-tool machines is this blade compatible with?
This blade uses a universal 57mm arbor interface, which is compatible with most oscillating multi-cutter tools. No additional adapter is required for machines with a standard universal arbor connection.
Why choose a diamond grit coating over a standard carbide grit blade for this type of work?
Diamond grit provides extreme cutting performance and extra-long service life, particularly on hard and abrasive materials such as tile, porous concrete, and brick. This translates to fewer blade replacements and more consistent results over the course of a project.
