CMT OMM27-X1 2-9/16" Coated Radial Saw Blade with Diamond Grit is a precision-engineered oscillating multi-tool accessory from CMT, designed for demanding cutting and routing tasks in hard and abrasive materials. Built around a universal arbor interface with a 65mm diamond-coated segment, this radial saw blade delivers extra-long service life when working with tiles, plasterboard, porous concrete, construction materials, epoxy, and glass fibre-reinforced plastic. Whether you are removing grout joints on wall or floor tiles, cutting smaller openings in soft wall tiles, or routing recesses in a boat's hull made from epoxy or glass fibre composites, this blade is engineered to handle the challenge with consistent, reliable results. Sold as a single-piece accessory, it fits directly onto most universal arbor multi-cutters for immediate use.

Key Features

• Diamond Grit Coating: The entire cutting surface is coated with industrial diamond grit, giving the blade extreme cutting performance and a significantly longer working life compared to carbide grit alternatives when used on tiles, porous concrete, epoxy, and other abrasive construction materials.
• Universal Arbor Compatibility (65mm): The 65mm universal arbor interface fits the vast majority of oscillating multi-tool platforms, meaning you can mount this blade on popular machines from multiple manufacturers without adapters or additional hardware.
• 2-9/16" Blade Diameter: At 2-9/16 inches, this radial saw blade provides a practical working width for routing joints, shaping cutouts, and making recesses - giving you controlled reach into tile joints and surface materials without sacrificing maneuverability.
• 0.079" Kerf Thickness: The blade's 0.079-inch tooth thickness creates a precise, consistent kerf that minimises material removal and helps keep cuts clean and accurate in delicate surfaces like wall tiles and glass fibre panels.
• Multi-Directional Cutting Capability: The grit-coated surface cuts in multiple directions, enabling free-hand routing and shaping without needing to reposition the tool repeatedly - ideal for curved recesses or irregular joint patterns in tile work and composite materials.
• Extra-Long Life Design: CMT's diamond coating formulation is specifically optimised for extended blade life on abrasive and hard materials, reducing the frequency of blade changes and lowering total cost over the life of the tool.

Why This Product

• For tradespeople and DIYers working with tiles, porous concrete, or epoxy-based composites, the diamond grit coating provides the durability and cutting consistency that carbide grit blades simply cannot match on hard, abrasive surfaces.
• The universal arbor design eliminates compatibility guesswork - this blade connects directly to most oscillating multi-tool platforms, making it a versatile addition to any toolkit without requiring brand-specific adapters.
• From routing grout joints on wall and floor tiles to cutting recesses in glass fibre-reinforced plastic used in marine applications, a single blade handles a wide range of construction and renovation tasks - reducing the need to carry multiple accessories.
• The 0.079-inch kerf thickness and multi-directional cutting action give users precise, controlled results in close-tolerance applications like tile joint routing and recessing in composite panels, where accuracy matters as much as cutting speed.
