Metal Cutting Discs 115mm: Choosing the 4.5inch 115X3X22.2mm Cutting and Grinding Disc by Application Fit and Specification Checks

Start with your own requirements

Before comparing discs, write down:

• Tool: the angle grinder's disc size, arbor size and rated speed.
• Workpiece: the material you will cut or grind most often, such as carbon steel, stainless steel or iron.
• Task: heavier cutting and grinding work, or thin, low-loss cuts.
• Market requirements: the safety standard and certificate documents your destination market or customers expect.
• Order profile: expected volume compared with the published minimum order, plus packing needs.

Key specification checks

1. Dimensions and arbor fit

The 115X3X22.2mm product is listed as 4.5inch, 115x3x22mm (item no. FAC115X3.2X22). The description also gives 1/8" (3.2mm) thickness and 4.5"x1/8"x7/8" wheel dimensions. Make sure the 22.2mm (7/8") bore suits your grinder. Ask which thickness, 3mm or 3.2mm, applies to the item you are quoting.

2. Disc type

The short description lists the type as T27 Depressed Center. Another part of the description calls the range "Flat Cut Off Wheels". Profile affects guard fit and how the disc is used, so get the exact type confirmed for your order.

3. Abrasive and application

The source lists aluminum oxide as the abrasive. The specification table says white aluminum oxide and gives 24# grit. Listed uses include steel, stainless steel, iron, aluminum and other alloys. The description also mentions structural steel, steel pipe, rebar, sheet metal and galvanized steel. If you mainly cut non-metal materials, check with the supplier before relying on this disc.

4. Speed rating

The product is listed with a max speed of 80 m/s. The excerpt for this disc gives no rpm figure. Ask for the rpm marking and check it against your grinder's rated speed.

5. Certificates and documentation

The product page names ISO, MPA and EN12413 in one place. Its specification table lists "MPA EN13743, ISO9001:2008, ISO14001, etc". Because these entries differ, ask for current certificate copies that cover this exact product before you use any certification in your own market.

6. Packing and commercial terms (to be confirmed)

The published table lists:

• packing of 100/400 pcs per carton
• carton size of 24.5×24.5×15.7 cm
• gross weight of 11 kg and net weight of 10 kg
• HS code 68042210
• minimum order of 5000 pcs
• loading port Xingang or other
• payment by T/T, L/C or Trade Assurance
• delivery 30–45 days after prepayment

The page mentions samples in two ways: within 3 days, and a free sample service for performance testing. Treat all of these as reference points for your quotation, not as commitments.

When a thinner 115mm disc may fit better

The same range includes the GRASSLAND 4.5inch Steel Abrasive Cutting Disc 115mm (115x1x22.2mm, item no. FSC1151222). Its page describes it as a 115mm thin metal cutting disc for fast, burr-free cutting with minimal material loss on carbon steel and ferrous metals. It also lists stainless steel, pipe, iron and copper as uses.

If your work is mainly thin, low-loss cuts in steel, the 1.2mm disc is the closer match on paper. If you want one 115mm disc listed for both cutting and grinding, the 115X3X22.2mm product is the one to assess. This guide doesn't claim that either disc lasts longer or cuts faster in your application. Run a sample trial under your own conditions to settle that.

Questions to resolve before ordering

• The exact thickness and profile (T27 depressed center or flat) for the 115X3X22.2mm item.
• The rpm marking and the full safety instructions. The published usage note is cut off in the source.
• Current certificates that cover the exact item and its markings.
• MOQ, lead time, sample terms and packing for your order quantity.
