Merryland 115 Cutting Disc
The Merryland 115 Cutting Disc is designed for metal and stainless steel applications. Its construction combines German phenolic resin with refined calcined and white corundum, delivering a long life and smooth cutting. The disc features a 1.0 mm ultra-thin profile and two layers of reinforced fiberglass mesh, supporting higher RPMs up to 13,300 and meeting EN 12413 safety standards. This universal disc is suitable for metal, INOX, steel pipe, and sheet metal, offering robust performance for general metal fabrication and maintenance tasks.
SATC 115mm Cutting Discs, 20-Pack
These SATC cutting discs are built for fast, precise metal cutting with a 1 mm ultra-thin edge. The discs use a resin-alumina-silicon carbide blend and feature double-layer glass fiber mesh, reducing vibration and extending life in demanding cut-off tasks. They comply with EU EN12413 standards and provide stable performance across steel, iron, aluminum, and other ferrous metals, helping minimise waste while maintaining clean cuts.
WORKPRO 10-Pack 115mm Cut Off Wheels
The WORKPRO set includes 115 x 22 x 1.2 mm cut-off wheels designed for 115 mm angle grinders. Crafted from corundum and aluminum oxide grains, they are reinforced with double fiberglass mesh for durability and reduced vibration. The 1.2 mm thin profile enables fast, precise, and clean cuts with minimal burrs and material waste, making them suitable for metal fabrication, construction, and repair work.
SATC 115mm Cutting Discs, 10-Pack
This 10-disc SACAT set mirrors the 1 mm ultra-thin design, delivering smooth fast cutting for steel, iron, aluminum, and other ferrous metals. The discs employ a high-quality resin matrix with alumina and silicon carbide, paired with double-layer glass fiber mesh to minimise vibration and maximize stability at high speeds, aligning with EN12413 compliance for reliable metal cutting in workshops and on-site projects.
Merryland 125 Cutting Disc
The 125 mm Merryland disc extends the same build quality to larger cutting tasks, using German phenolic resin and white corundum to deliver robust life and consistent cuts. With a 1.0 mm thickness and two reinforced fiberglass mesh layers, it meets EN 12413 and carries a maximum RPM around 12,250. It’s suitable for metal, stainless steel, and various alloys, supporting heavier-duty metalworking jobs with dependable performance.
Bosch 115mm Metal Longlife Disc
Bosch’s 115 mm metal longlife disc is designed for efficient metal cutting with a bore size of 22.23 mm, making it compatible with standard small angle grinders. The focus is on longevity and performance for metalworkers who need consistent cuts across steel and other metals. The disc is engineered to deliver reliable life while accommodating typical workshop and portable grinding setups, reflecting Bosch’s emphasis on professional-grade accessories.
Buying Guide: Key Purchase Considerations
- Disc diameter and bore compatibility: Ensure the disc diameter (115 mm or 125 mm) and bore size (22.23 mm) match your grinder model. Incompatible sizes can cause unsafe operation or poor fitment.
- Cutting edge thickness: Ultra-thin discs (1.0 mm to 1.2 mm) offer faster cuts and less material waste but may wear more quickly under tough materials. Thicker discs tend to last longer but cut slower.
- Reinforcement and safety standards: Look for discs with dual fiberglass mesh reinforcement and EN 12413 certification for reliability and safety under high RPMs.
- Material compatibility: Consider the metals you work with most often (steel, stainless steel, aluminum). Some discs are optimized for ferrous metals, others for stainless steel or multi-material use.
- RPM rating and grinder compatibility: Match the disc’s maximum RPM to your grinder’s capabilities. Exceeding the rating can cause disc breakage and safety hazards.
- Vibration and balance: Discs with reinforced cores and double mesh help reduce vibration, improving control and reducing operator fatigue on longer cuts.
- Cost-per-cut: While initial price matters, evaluate lifespan and replacement frequency. A disc with slightly higher price but longer life may deliver lower overall costs.
- On-site versus workshop use: For rough site work, durability and quick cutting may be prioritised; for precise fabrication, consistency and edge quality matter more.
- Safety practices: Always wear eye protection, gloves, and a face shield. Secure workpieces and use clamps to prevent movement during cutting.
