This Diamond Blade is the best option for degrouting all types of tile joints and especially for epoxy grout joints to give longest service life. The blades generate no airborne dust and are "tile safe" since the oscillation action does not cause the blade to climb out of the tile joint like other tools. The round blades are 3-1/8" diameter, will cut up to 3/4" deep and are bell-shaped to allow flush degrouting. Cutting width is about 3/32".
Not intended for cutting ceramic tile or stone.
