Bosch EXPERT 125mm Blue Metal Sanding Disc

The Bosch EXPERT R444 125mm Blue Metal Sanding Disc delivers an impressive finish on a wide range of metal surfaces. Featuring a stable vulcanised fibre backing, it enables a steady, consistent grinding process — making it equally suited to controlled finishing work and more demanding material removal tasks.

Its semi-friable aluminium oxide abrasive grit is specifically engineered for metal applications, bonded with fully synthetic resin for high work stability and optimal sanding results. Compatible with standard angle grinders via a 22.23mm bore, it is designed for use with a suitable backing pad.

Ideal for deburring, welding preparation, and blending on carbon steel, mild steel, aluminium, non-ferrous metals, and cast iron — it also excels at removing discolouration, stock, and surface imperfections. Available in 80g, 100g, and 120g grits to suit different stages of metalwork.
