CMT 3-3/8" Diamond Coated Radial Saw Blade with Starlock Arbor by CMT is a precision oscillating accessory designed for demanding cutting, grooving, and cleaning tasks on hard abrasive materials. Fitted with a Starlock arbor interface for a secure, tool-free mount on compatible multi-cutters, this 75mm (2-15/16") diamond grit blade delivers extra-long service life when working through tile joints, grout lines, porous cement, plasterboard, construction materials, and even teak seams on boat decks. Whether you are routing recesses for concealed cables, cleaning hard epoxy resin or cement jointwork, or cutting grout from tiled walls and flooring panels, the all-over diamond coating allows free-hand movement and multi-directional cutting in tight corners and along edges where standard carbide blades struggle.

Key Features

• Starlock Arbor Interface - compatible with any Starlock-mount oscillating multi-cutter, including CMT and Metabo machines, ensuring a rigid, rattle-free blade connection for accurate cutting.
• 75mm (2-15/16") Radial Saw Blade Diameter - sized to reach into confined areas and work close to corners and edges where larger blades cannot fit.
• Diamond Grit Coating - delivers extra-long life compared to carbide grit on tiles, porous cement, bricks, and other abrasive masonry materials, reducing blade swap frequency on demanding jobs.
• Multi-Directional Cutting Surface - the all-over grit pattern cuts in any direction, enabling free-hand routing, shaping, and grooving without repositioning the workpiece.
• 0.087" Kerf Thickness - a controlled, narrow cut width minimizes material removal and keeps grout lines, seams, and joints clean during precision work.
• Ideal for Corner and Edge Work - the radial geometry and compact diameter allow the blade to operate right up to wall edges, floor borders, and inside corners, reducing the need for hand finishing.
• Sold as a 1-Piece Unit - supplied individually so you can replace or add exactly what your project requires without purchasing unneeded extras.

Why This Product

• When cutting grout from tiled walls or removing epoxy resin from flooring joints, the diamond grit coating maintains cutting performance far longer than carbide alternatives, making it a cost-effective choice for masonry and tile renovation work.
• The Starlock arbor system provides a universal fit across Starlock-compatible oscillating tools, so professionals who already own CMT or Metabo multi-cutters can use this blade immediately without adapters or modifications.
• Tasks such as grooving porous cement for concealed pipe or cable runs, or cleaning teak seams on boat decks, require a blade that cuts in multiple directions without constant repositioning - the all-over diamond grit surface handles this naturally.
• The compact 75mm diameter and thin 0.087" kerf make this blade particularly useful for close-quarters work near corners and edges, preserving surrounding tile and material surfaces while targeting only the intended seam or joint.
