Cutting Wheel with Guard Dedra 16 x 300 mm – metal and masonry abrasive disc

Dedra 16 x 300 mm cutting wheel with guard is an abrasive disc designed for use with angle grinders to cut metal and masonry. The 300 mm diameter and 16 mm bore make it suitable for machines that accept large cutting discs. The product includes a protective guard to reduce spatter and direct debris away from the operator, enabling safer operation when performing heavy-duty cutting tasks in construction, metalworking, or renovation.

Advantages

The cutting wheel is engineered for clean, efficient cutting of both metal and masonry materials. Its large diameter provides greater cutting depth per pass, reducing the number of cuts needed for thick materials. The included guard helps contain sparks and fragments and supports stable, controlled cutting. The abrasive composition balances cutting performance and disc life for typical construction and workshop applications.

Suitable for

• Cutting steel beams, rods and sheet metal
• Cutting concrete blocks, bricks and masonry elements
• On-site construction and renovation cutting tasks
• Metalworking shops requiring large-diameter cutting discs

Key specifications

• Diameter: 300 mm
• Bore (arbor) diameter: 16 mm
• Material compatibility: metal and masonry
• Type: abrasive cutting wheel with protective guard
• Designed for use with angle grinders accepting 300 mm discs

How to use

Mount the cutting wheel on an angle grinder that accepts a 300 mm disc and a 16 mm arbor, following the grinder manufacturer’s instructions for safe mounting and wheel orientation. Ensure the protective guard is correctly fitted and tightened before operation. Secure the workpiece and wear appropriate personal protective equipment including eye protection, hearing protection, gloves, and respiratory protection when cutting masonry. Start the grinder and allow it to reach full speed before engaging the cut; use steady, even pressure and avoid forcing the disc through the material. After finishing, allow the wheel to stop completely before setting the tool down and inspect the disc and guard for damage before subsequent use.

Usage recommendations

Use the cutting wheel within the speed limits specified by your angle grinder and replace the disc if any cracks, chips, or excessive wear are visible. For masonry cutting, consider wetting the work area to reduce dust where appropriate and permitted. For repetitive metal cutting, plan cuts to allow cooling intervals to prolong disc life. Always follow local safety regulations and the angle grinder manufacturer’s instructions.
