Merryland 115 Cutting Disc for Metal

The Merryland 115 mm cutting disc is designed for universal metal work, including stainless steel (INOX) and other alloys. It utilises German phenolic resin and refined calcined white corundum to deliver long life and smooth cuts. The disc is 1.0 mm thick, with two layers of reinforced fiberglass mesh, supporting high rigidity and reduced wobble during cutting. It is rated for up to 13300 RPM and adheres to European EN 12413 standards, providing a reliable option for both professional and DIY use. Suitable applications include cutting metal sheets, steel pipes, and angle iron with consistent performance across a range of metals.
Key features include a long-life performance, reinforced safety structure, and wide material compatibility. The universal use classification means this disc can handle stainless steel, metal, and plastic in many work environments. The combination of durable materials and precision engineering aims to minimize disc wear and maintain cut quality over time.
SATC 20-Piece 115mm Metal Cutting Discs

These SATC discs are built for long life and stable performance, combining resin, alumina, and silicon carbide to achieve durable cutting action. The double-layer glass fiber mesh enhances rigidity and reduces vibration, contributing to smoother cuts and less user fatigue at higher speeds. The 1 mm ultra-thin edge supports fast, straight cuts with minimal material waste, making them well-suited for cutting steel, iron, and other ferrous metals. Compliance with EU EN12413 confirms alignment with industry safety standards.
Ideal for high-volume tasks, these discs balance lifespan, speed, and cutting precision. The design emphasizes consistent results across multiple discs, which is advantageous for projects requiring repeated cuts with dependable performance. They are a strong choice for metal fabrication and utility tasks in workshops and on-site jobs.
SATC 115mm 50-Piece Cutting Discs

The SATC 50-piece kit provides a broad selection of 115 mm discs with 1.0 mm thickness, designed for heavy-duty metal cutting needs. The discs incorporate a double-layer fiberglass mesh and a reinforced core to help mitigate vibration, preserve disc integrity, and extend service life. These discs comply with EN12413, ensuring alignment with safety and quality expectations for professional environments. With 50 discs included, users can maintain workflow continuity on larger jobs or multiple projects without frequent reordering.
Users should expect fast, straight cuts with minimal waste, supporting efficient results across a variety of metals, including steel, iron, and other ferrous materials. The set’s breadth makes it a practical option for small workshops or tradespeople who regularly perform metal cutting tasks.
TOLESA Diamond 115 x 22.23mm Disc

The TOLESA diamond cutting disc offers a different cutting mechanism, with diamond abrasive grains on both sides of the core. This construction yields smooth and precise cuts while reducing heat buildup during cutting, which is particularly beneficial for hard metals and rebar. The core is an alloy steel body that provides durability and strength, contributing to reliability under demanding conditions. The disc is capable of delivering a high number of cuts—over 5000 in some uses—making it a strong option for repetitive, high-volume metalwork tasks.
Diamond discs are known for reduced dust and longer-lasting performance compared to traditional bonded abrasives. While typically more expensive upfront, the potential cost-per-cut and improved lifespan can be advantageous for professionals dealing with tough materials or frequent cutting work. This disc targets rebar, steel, INOX, and similar metals, delivering robust results with improved safety and efficiency.
WORKPRO 115 mm Metal Cutting Discs

WORKPRO’s 115 mm discs offer compatibility with standard 115 mm angle grinders, featuring a 1.2 mm thickness and the ability to operate up to 13,300 RPM. The discs use high-grade corundum and aluminium oxide abrasive grains, reinforced with double fiberglass mesh for added strength. The 1.2 mm thin profile is designed to deliver aggressive cutting with less material waste and burr formation, resulting in cleaner finishes on metal workpieces. This set is well-suited for metal and stainless steel cutting tasks, providing dependable performance for both professional and DIY applications.
In terms of durability and cutting speed, these discs strike a balance between lifespan and cost. The 1.2 mm thickness offers a practical compromise for users who need precise cuts without excessive disc wear. The reinforced structure helps minimize vibration, contributing to safer and more controlled operation during extended cutting sessions.
Buying Guide: Key Purchase Considerations For Metal Cutting Discs
- Disc material and construction: Bonded abrasive discs are common and cost-effective for standard metal cutting. Diamond discs offer superior wear resistance for hard materials but at higher cost. Consider the material you cut most often (steel, INOX, rebar) to choose the appropriate option.
- Disc thickness: Thinner discs (around 1.0 mm) enable faster cuts with less material removal but may wear faster or be less durable under heavy loads. Slightly thicker discs (1.2 mm) provide more durability and strength, reducing the risk of warping or breakage on tougher cuts.
- Reinforcement and safety: Look for discs with reinforced fiberglass mesh and compliance with EN12413 or equivalent standards. These features help reduce breakage risk and manage vibration during cutting.
- RPM rating and compatibility: Ensure the disc’s max RPM aligns with your grinder’s speed. Most 115 mm discs are suitable for common 13,300 RPM grinders, but always verify the tool’s specification before use.
- Quantity and continuity: For larger projects, a multi-pack (20–50 discs) reduces downtime spent ordering substitutes. Consider sets that cover the metals you frequently cut (ferrous vs. non-ferrous).
- Dust and debris: Diamond discs can produce less dust and maintain shape better than bonded abrasives in some applications, contributing to a cleaner working area and longer disc life.
- Cost-per-cut: While price is important, evaluate the long-term value. A higher upfront cost per disc may translate to lower total project costs due to longer life and faster cutting.
- Safety considerations: Always wear appropriate PPE, secure the workpiece, and ensure the grinder is rated for continuous operation. Use clamping and guards as recommended by the manufacturer.
