Product Description
CMT OMF118-X5 Carbide Grit Radial Saw Blade with Starlock Arbor - 5-Piece Pack by CMT is a segmented oscillating blade engineered for demanding cutting, grooving, and joint-cleaning tasks in hard construction materials. Designed to fit multi-cutters with a Starlock arbor, this 2-15/16 in. carbide grit blade tackles grout removal, porous cement grooving, tile joint cleaning, and recessed cable or pipe routing - jobs that demand a tough, abrasion-resistant cutting edge rather than conventional toothed geometry.
Key Features
- Carbide Grit Segmented Blade - tungsten carbide grit bonded to a segmented profile cuts aggressively through grout, tile adhesive, aerated concrete, and epoxy resin joints without chipping the surrounding material.
- Starlock Arbor Interface - the Starlock mount provides a secure, wobble-free connection to compatible multi-cutters from CMT, Metabo, and other Starlock-platform tools, transferring full oscillating power to the blade.
- 0.087 in. Kerf Thickness - a narrow cutting kerf keeps material removal controlled and precise, ideal for cleaning teak deck seams, cutting grout lines, or grooving porous cement without excessive waste.
- Multi-Directional Grit Cutting Surface - grit coated on the cutting edge works in multiple directions, enabling free-hand routing and shaping through hard epoxy resin, cement jointwork, and flooring panel seams.
- 5-Piece Pack - includes 5 identical blades, reducing downtime on extended jobsite tasks where blade wear is expected when working through abrasive masonry and composite materials.
Why This Product
- For contractors and tradespeople tackling grout removal, concealed wiring channels, or teak seam cleaning, the carbide grit surface cuts through hard, abrasive materials that would rapidly dull conventional oscillating blades - making this a purpose-built solution rather than a general-purpose workaround.
- The 5-piece value pack means a single purchase covers multiple passes, multiple operators, or blade rotation on long grooving or joint-cleaning runs in porous cement and construction materials, reducing trips to restock mid-project.

Frequently Asked Questions
What tools are compatible with the Starlock arbor on this blade?
This blade is designed for multi-cutters equipped with a Starlock arbor. Compatible machines include Starlock-platform oscillating tools from CMT and Metabo, among other manufacturers that use the Starlock interface.
Why is a carbide grit blade used instead of a toothed blade for these applications?
Carbide grit blades are designed for cutting abrasive, hard materials such as grout, porous cement, epoxy resin, and tile adhesive that would quickly wear down or chip a conventional toothed blade. The grit surface also cuts in multiple directions, which is important for free-hand routing and shaping in joints and seams.
What does the segmented blade design offer for joint and seam work?
The segmented configuration helps the blade clear debris from the cut zone during grooving and joint-cleaning work, maintaining cutting efficiency when working through tile joints, plasterboard, and porous cement over extended use.
