The CMT OMM25-X1 3-1/8" Delta Rasp with Carbide Grit is a heavy-duty oscillating multi-tool accessory engineered for aggressive material removal across a wide range of construction and renovation surfaces. Fitted with a universal arbor for broad machine compatibility, this triangular carbide grit rasp delivers multi-directional cutting action that makes it equally at home rasping wood, removing mortar or tile adhesive, rough-grinding filler, and working through porous concrete, plasterboard, carpet adhesive residues, and other tough building materials. Sold as a single piece, it is a go-to attachment whenever precision shaping or coarse surface preparation is required on the job site.

Key Features

• Universal Arbor Compatibility - fits most oscillating multi-cutters on the market, so you can put this rasp to work without hunting for a machine-specific adapter or replacing existing tools.
• 80mm (3-1/8") Carbide Grit Delta Rasp - the triangular delta shape reaches into corners, tight recesses, and confined spaces where flat or round accessories cannot, making detail work and joint routing far more efficient.
• Carbide Grit Coating - tungsten carbide grit delivers extreme hardness and long service life when cutting through tile, stone, concrete, and wood, reducing the need for frequent accessory changes mid-task.
• Multi-Directional Cutting Surface - the grit-coated face removes material on every stroke direction, giving the user free-hand control for shaping, rasping, and rough grinding without repositioning the tool repeatedly.
• Broad Material Compatibility - rated for tiles, plasterboard, porous concrete, construction materials, wood, and carpets, this single accessory handles the variety of substrates typically encountered during remodeling or new construction work.
• Mortar, Adhesive, and Carpet Adhesive Removal - the aggressive carbide surface strips mortar, tile adhesive, and carpet adhesive residues efficiently, reducing manual scraping time and physical effort on prep work.

Why This Product

• A single carbide grit delta rasp that handles tiles, porous concrete, plasterboard, wood, and carpet adhesive residues means fewer accessory swaps and faster workflow across mixed-material job sites.
• The universal arbor design removes compatibility guesswork - this rasp connects directly to most oscillating multi-cutters already on the job, saving time and additional equipment costs.
• The delta (triangular) profile is purpose-built for reaching into corners and along joints where flat-profile rasps leave material behind, making it especially valuable for tile adhesive removal, grout joint work, and wood shaping in tight areas.
• Carbide grit construction provides the hardness needed to work through concrete, stone, and tile without the rapid wear associated with standard abrasive accessories, extending the useful life of each attachment.
