Product Description
CMT 3-3/8" Carbide Grit Radial Saw Blade with Starlock Arbor by CMT is a segmented oscillating blade engineered for demanding material removal tasks - grout line cleaning, joint cutting in tile and flooring, grooving in porous cement, and routing channels for concealed cables or pipes. The carbide grit coating delivers aggressive, multi-directional cutting action that handles hard epoxy resin, cement jointwork, plasterboard, and construction materials with precision. Sold individually.
Key Features
- Starlock Arbor Interface - fits Starlock-compatible oscillating multi-tools from CMT, Metabo, and other Starlock-platform machines, providing a secure, tool-free blade swap and maximum power transfer during heavy-duty cutting sessions.
- Carbide Grit Coating - tungsten carbide grit bonded to the blade surface cuts in all directions, allowing free-hand routing and shaping without needing to reposition the tool - ideal for irregular grout lines and curved seams.
- Segmented Blade Design - the segmented profile reduces heat buildup and debris accumulation during cuts in porous cement, plasterboard, and tile joint applications, extending working life and maintaining consistent cutting performance.
- 0.087" Teeth Thickness - a precise kerf width suited for cutting out grout on walls, cleaning teak seams on boat decks, and removing very hard epoxy resin or cement jointwork without excessive material loss.
- 75mm (2-15/16") Blade Diameter - a compact cutting diameter optimized for controlled, detail-oriented work in flooring panels, wall tiles, and tight construction spaces where a full-size blade would be impractical.
- Broad Material Compatibility - rated for tile joints, plasterboard, porous cement, aerated construction materials, hard epoxy resin, cement joints, and teak deck seams - one blade handles a wide range of jobsite tasks, reducing the need to swap accessories.
Why This Product
- Purpose-built for grout removal and joint cleaning in tile, flooring, and wall applications - the carbide grit segmented design cuts into hard epoxy resin and cement jointwork where standard blades fall short.
- Starlock arbor compatibility means this blade mounts to Starlock oscillating tools without adapters, delivering full oscillating power directly to the cutting surface - no slippage, no wasted motion.
- The multi-directional carbide grit surface enables free-hand routing for laying concealed cables or pipes and grooving in porous cement - versatile enough to replace multiple specialty accessories on a single job.
- Sold as a single unit so you can add exactly the quantity needed without committing to multi-pack quantities - practical for targeted replacement or single-application use.

Frequently Asked Questions
What arbor system does this blade require?
This blade uses a Starlock (SL) arbor interface. It is compatible with Starlock oscillating multi-tools, including machines from CMT and Metabo, as well as other tools built on the Starlock platform.
Can this blade be used to clean teak seams on boat decks?
Yes. The segmented carbide grit radial saw blade is specifically listed for cleaning teak seams on boat decks, in addition to grout joints, epoxy resin removal, and cement joint cleaning on standard construction applications.
What is the blade diameter and kerf thickness for this oscillating blade?
The blade has a diameter of 75mm (2-15/16") and a teeth thickness of 0.087". These dimensions make it well suited for controlled joint cleaning, grooving, and recess routing in tight or detail-oriented work areas.
Is the carbide grit coating able to cut in multiple directions?
Yes. Because the cutting surface is coated with carbide grit rather than directional teeth, the blade cuts in multiple directions simultaneously. This makes it effective for free-hand routing and shaping tasks such as grooving in porous cement or removing irregular grout and epoxy resin joints.
