Choosing 9 Inch Angle Grinder Discs 230mm X 6 X 22.2mm 3 Nets T27: Application Fit and Specification Checks

1. Start with the job: grinding, not cutting

The product listing describes this disc as a metal grinding disc. Its stated application is polishing and grinding metal welds. The description also mentions grinding, deburring welds, dressing and aggressive stock removal.

Listed workpiece materials:

• Ferrous metals and steel
• Stainless steel
• Rebar, iron pipe, bar stock and metal tubing

Listed work settings include tank fabrication, power plant maintenance and repair, and welding or metal fabrication shops.

When this disc does not apply: If the main task is cutting through rebar, channels, angle profiles, pipes or sheet, use the 9 Inch 230mm X 3mm X 22.23mm abrasive cutting disc (item DAC2303022). It is for ferrous metal and steel cutting. Metal cutting discs must always meet the workpiece at a 90º angle, and choose a metal or stone disc to match the material.

2. Check mounting fit and dimensions

The thickness figures do not match. Confirm the actual thickness for the batch you order, especially if your tooling, guards or packaging depend on it.

3. Check speed rating against your machines

The listing gives a maximum working speed of 80 m/s and a maximum of 6,650 RPM. One table in the same listing shows the RPM as ">6650", which conflicts with the stated maximum. Ask for the speed marking printed on the disc and label before you approve the product. Make sure the 230 mm grinders your end users run are compatible with that marked rating.

4. Abrasive, grit and hardness

• Abrasive: The description lists brown aluminium oxide with heat-treated aluminium oxide grains. One information table instead says "brown aluminum oxide and silicon carbide". Confirm the abrasive if it matters for your application.
• Grit: The listing gives 24#, 30# and 46# in one place, and 24# and 30# in another. The description refers to a single 24-grit structure, and the specification code reads A24/30R-BF27. Specify the grit you need on the purchase order.
• Hardness: R grade.
• Bond and reinforcement: Resin bonded over fiberglass mesh, described as balanced to avoid vibration during use. The listing does not explain what "3 Nets" in the product name means beyond "reinforced fiberglass", so ask for the reinforcement structure in writing if it is part of your specification.
• Colour: Black.

5. Standards, documents and commercial terms

The listing says the disc complies with EN 12413 and lists MPA EN12413 and ISO9001 as certificates. Buyers should ask for the current certificate documents rather than rely on the listing text alone. Other listed details:

• HS code: 68042210
• Packaging: kraft carton and pallet
• Loading port: Tianjin or other ports
• OEM service: acceptable

The listing gives no price, minimum order quantity or delivery time for this disc, so this guide makes no commitment on any of them. Request a quotation for your target market and quantity.

Quick selection checklist

1. Is the task weld grinding, deburring, dressing or stock removal on ferrous metal, steel or stainless steel? If yes, this disc fits the listed application.
2. Is the task cutting through stock? If yes, consider a cutting disc instead.
3. Do your grinders take a 230 mm Type 27 disc with a 22.2 mm (7/8") bore?
4. Have you confirmed thickness, grit, abrasive and the marked maximum speed in writing?
5. Have you received the certificate documents your market requires?
