Cutting Disc for Metal Bosch Standard for Metal A 30 S BF 115 mm — for steel, cast iron, non-ferrous metal, metal pipes, profiles

Bosch Standard for Metal A 30 S BF is a 115 mm cutting disc engineered for straight, efficient cuts in a range of ferrous and non‑ferrous metals. The abrasive composition and bonded construction deliver consistent cutting speed and predictable wear for general workshop and construction use. The disc is designed to fit angle grinders that accept 115 mm cutting wheels and is intended for tasks such as cutting steel sheets, cast iron parts, metal pipes and structural profiles.

Advantages

The disc offers stable cutting performance and good material removal rate for routine metalwork. Its bonded abrasive formulation provides a balance between cutting speed and wheel life, while the thin profile reduces cutting time and heat buildup. The product is suitable for workshop and on‑site use, providing reliable results on common metals including steel, cast iron and non‑ferrous alloys.

Suitable for

• Cutting steel sheets and plates
• Severing cast iron components
• Cutting metal pipes and tubing
• Trimming structural profiles and angle iron
• On‑site repair and maintenance metal cutting

Key specifications

• Disc diameter: 115 mm
• Abrasion type: bonded abrasive wheel suitable for metal cutting
• Designed cut type: straight cuts
• Material compatibility: steel, cast iron, non‑ferrous metals
• Suitable tool: angle grinder accepting 115 mm discs
• Typical application: workshop and construction metal cutting tasks

How to use

Fit the 115 mm cutting disc to an angle grinder following the tool manufacturer’s safety and mounting instructions. Ensure the guard is in place and that the disc rotation direction matches the arrow on the wheel. Use firm, steady pressure and allow the disc to do the cutting rather than forcing it; make straight passes for clean cuts. Keep cutting speed consistent and avoid side loading the disc. Replace the disc if you notice excessive vibration, chipping, or uneven wear.

Usage recommendations

Always wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Use the disc only within the speed limits specified by the angle grinder and discard the disc if it is cracked, severely damaged or worn down to the reinforcement layer. For best results on thicker materials, make multiple light passes rather than attempting a single deep cut.
