A 150mm DIA THERMO replacement grinding disc for the Festool Thermo Diamond Tool Head — engineered specifically for the materials that defeat ordinary grinding discs by smearing under friction heat. The diamonds are arranged so the disc scrapes the material away rather than sanding it, so heat-sensitive coatings cannot melt and clog the cutting surface the way they do on conventional diamond tooling.
Use this disc for the work it is built for: thermoelastic floor coatings, bitumen, vinyl adhesive residue, asphalt coatings, line markings on concrete, and the soft polymer coatings that smear when sanded and gum up standard diamond discs within minutes. The DIA THERMO disc keeps cutting where ordinary discs glaze, clog and stop working, and the temperature-resistant diamonds are engineered for a long service life under the heat these materials generate.
The disc attaches to the DIA THERMO-D150 tool head in just a few steps when the original wears out. Festool stocks spare parts and consumables for at least ten years after a machine leaves the current range, so renovation grinders and their tooling stay supported with genuine replacement parts. A genuine Festool DIA THERMO disc — chosen by floor-preparation specialists, line-marking removal contractors and renovation crews tackling the work that defeats ordinary diamond grinding.
