Choosing Grassland 9 Inch 230mm X 2 X 22 Stainless steel Carbon Steel Cutting Disc: Application Fit and Specification Checks

1. Start with your own requirements

Gather these details before you compare specifications:

• Machine type and spindle: what tools will run the disc (angle grinders or stationary machines), what their rated speed is and what arbor size they take.
• Workpiece material: carbon steel, stainless steel, hardened steel or alloy, cast iron or building materials.
• Cut quality: whether operators need thin, precise cuts with little material loss.
• Compliance: which standards and documents your market or customers require. The site's target markets include the United States, the Middle East, Europe and Southeast Asia. Check the local requirements for each one rather than assuming they are the same.
• Order volume and logistics: quantity, carton handling and shipping port.

2. Dimensions and arbor fit

The short description lists the size as 230mm x 2.0mm x 22.23mm. The detailed description lists 230mm x 1.9mm x 22.2mm bore (9″ x 5/64″ x 7/8″).

How to check fit:

• The 230mm (9-inch) diameter has to suit the guard and the tool's capacity.
• The roughly 22.2mm (7/8″) bore has to match the arbor and flanges.
• The two thickness values (2.0mm and 1.9mm) do not agree. Ask the supplier which one applies to your order, especially if kerf width or material loss matters to you.

The listing warns that flanges that are too small or inaccurate can damage the cutting blade. Inspect your flanges before you buy.

3. Speed rating

The short description gives 6650 rpm and 80 m/s. The specification table gives a max. working speed of 80 m/s and a max. permissible speed of 6600 rpm.

The 80 m/s figure is the same in both places, but the rpm values differ. Make sure your machine's rated speed does not exceed the speed marked on the disc you receive, and ask the supplier to confirm the rpm marking.

4. Abrasive, bond and grade

According to the product information:

• Abrasive: aluminium oxide grit. The table says "Brown corundum", and the description says a mix of brown aluminium oxide and white aluminium oxide.
• Reinforcement and bond: fibreglass reinforcement with a resin bond, intended to provide both safety and cutting performance.
• Grade: A46RBF.
• Customisation: the listing says product quality can be customised. Discuss your requirements with the supplier.

The advantages are higher cutting speed, low material loss and low noise. These thin cutting discs are suitable for precise, vibration-free metal cutting.

5. Application fit

Where the listing says the disc fits:

• Cutting steels, stainless steels, hardened steels, cast iron and building materials, according to the product description. The specification table lists the use more narrowly as "Stainless Steel and harden alloy".
• Manual use on angle grinders and use on stationary machines.
• Jobs that need thin, accurate, fast metal cuts.

Where it does not apply:

• Any operation other than cutting or grooving. The listing strictly prohibits using the blade for other operations because uneven force can cause abnormalities. Do not use it as a grinding disc.
• Machines that run faster than the speed marked on the disc.
• Workpieces the disc does not match. The listing warns that a mismatch can cause abnormal wear, poor sharpness and abnormal heat.

If building materials are your main application, confirm suitability with the supplier first, since the two parts of the listing describe the intended use differently.

6. Standards and certificates

The short description says the disc is manufactured to the EN 12413 standard. The specification table lists certificates as "MPA EN13743, ISO9001:2008, ISO14001, etc.". The standard numbers do not match, and "etc." does not say what else is covered.

Before you rely on any of these for compliance, ask for the current certificate copies and check the scope, validity dates and standard numbers.

7. Packing and order terms in the listing

The listing gives the same figure for gross and net weight, so confirm the actual carton weight for freight planning. This guide gives no prices. Treat the MOQ, delivery time and payment terms as listed terms that need to be confirmed on your quotation, not as commitments. To evaluate performance on your own workpieces, ask about the listed free sample service.

8. Safety points from the product information

The listing includes these usage notes:

1. Before installing, check the disc for deformation, cracks or chips.
2. If the disc is marked with a rotation direction, it must match the machine's direction of rotation.
3. While the disc is rotating, never cut by hand or touch it with your hands or body. If anything abnormal happens during cutting, shut the machine down immediately.
4. When cutting is no longer sharp, trim and sharpen the cutting disc. Continuing to use it can overheat, overload and damage the disc.

These notes do not replace the machine manufacturer's instructions, the markings on the disc or your workplace safety rules.

Summary checklist

• The 230mm diameter and ~22.2mm (7/8″) bore match your tools and flanges.
• The supplier has confirmed the thickness (2.0 vs 1.9mm) and the rpm marking (6650 vs 6600).
• Your machine speed is within the disc's marked rating (80 m/s).
• The workpiece material is within the confirmed application scope.
• You have certificate copies for the standards your market requires.
• MOQ, packing, payment and delivery terms are confirmed on the quotation.
