The DREMEL MM515U is a 3-piece universal grout and tile oscillating blade assortment designed for use with oscillating multi-tools. This kit provides trade professionals and skilled DIYers with a selection of blades suited for cutting and removing grout, scoring tile, and working in tight spaces where rotary tools cannot reach. The blades feature a universal shank interface, making them compatible with a wide range of oscillating tool platforms. At 0.201 pounds, the assortment is lightweight and easy to store or transport to the job site.
This assortment is well suited for tile installation and regrouting work in residential and light commercial settings. Plumbers, tile setters, and general contractors frequently use oscillating blades when cutting around fixtures, removing old grout lines, or making precision cuts near finished surfaces. The multi-piece format allows a technician to match the right blade geometry to the specific task without carrying a full separate accessory kit.
Designed as an OEM-style accessory replacement and aftermarket addition compatible with oscillating multi-tools accepting universal-shank oscillating blade attachments.
Blade installation and removal should be performed with the oscillating tool unplugged or the battery pack removed. A licensed tile setter, general contractor, or experienced tradesperson typically handles grout and tile cutting applications. Eye protection and a dust mask are recommended when cutting grout or ceramic tile materials. Always follow the tool and accessory manufacturer guidelines for maximum accessory speed ratings before operation.
