Bosch 4.5" Steel Cutting Disc 1mm

Designed for ferrous metals, including steel and stainless steel, as well as other metal surfaces typically cut with angle grinders.

A 1mm thickness reduces kerf, allowing faster cutting with less resistance. This leads to quicker cuts, less material wastage, and smoother edges, especially on thinner sections of metal.

The disc is 4.5 inches in diameter and is described as universally compatible with most standard angle grinders. It fits common arbor sizes and guards found on many grinders.

The combination of a high-quality abrasive material and the ultra-thin 1mm profile enables fast cutting action, while the design helps minimize burr formation and maintain clean edges under heavy loads.

1) Power off and unplug the grinder. 2) Remove the existing disc and inspect the arbor for damage. 3) Align the disc with the grinder’s arbor and any alignment marks. 4) Securely tighten the nut and ensure the guard is in place. 5) Spin the disc by hand to check for wobble before use.

Use steady, moderate pressure and allow the disc to do the cutting rather than forcing it. Maintain a consistent feed rate, avoid overheating by taking light passes, and let the tool cool between heavy cuts. Keep the guard in place and use proper PPE.

Always wear eye protection, hearing protection, and gloves. Ensure the grinder’s guard is installed, inspect the disc for cracks or damage before use, and never use a damaged or shattering disc. Work in a clean, dry area and keep bystanders away.

Ideal for fabrication, construction, and repair work that requires fast and clean cuts in steel, stainless steel, and other ferrous metals. Suitable for cutting through metal sheets, bars, profiles, and structural components.

Yes. It offers fast cutting, cleaner edges, reduced material waste, and durability designed for repeated use, making it a cost-effective choice for professional or serious DIY metalworking tasks.

Inspect for visible signs of wear such as deep grooves, glazing, cracks, chips, or significant wobble. If the edge looks uneven, the disc vibrates abnormally, or you notice increased smoke or heat without effective cutting, replace it immediately to avoid unsafe operation.
