Diamond Disc - MAKITA (4.5-inch)

A 4.5-inch diamond disc from Makita, for the standard angle grinder. Where an abrasive cutting disc wears away as it works, a diamond disc grinds through with a rim of industrial diamond bonded to a steel body, so it survives material that would destroy an abrasive wheel in seconds - floor and wall tile, porcelain, concrete, block, kerbs, stone and paving. That durability is why it costs many times what a cutting disc does and why one lasts through jobs rather than hours. It is the disc used for cutting service chases into block walls, trimming tile on site, and cutting concrete lintels and slabs. Let the disc run at speed and feed it gently; forcing or twisting it glazes the rim and stops it cutting.
