How to Compare a 5 Cutting Wheel for Steel Work

Shared fit for 5-inch grinders

Both options specify a 125 mm outer diameter, a 22.23 mm bore, and a 3.2 mm thickness. Those dimensions identify the discs as a 5-inch format for hand-held angle grinders. Check the arbor size on the grinder and the guard arrangement before placing an order.

Both listings also specify a maximum working speed of 80 m/s and 12,250 rpm. The matching speed figures make this a useful first screening point for a fleet of compatible grinders. The operator should follow the grinder and wheel safety instructions for the actual cutting setup.

Where the specifications match

The two options list aluminum oxide as the abrasive material, resin as the bonding agent, R hardness, and 46# / 60# grit sizes. Both are described for ferrous metal and steel cutting, including pipes, rods, bars, angles, and irregular steel sections.

Reinforced fiberglass is part of both product descriptions. The listings describe flat cut-off discs, and both connect the reinforcement with cutting metal sections and profiles. Picture a maintenance team trimming steel pipe or cutting an angle section with a handheld grinder: the 125 mm diameter and 3.2 mm thickness are the dimensions to match against the tool and the planned cut.

Which listing fits your buying process?

The first option is the clearer choice for a buyer who needs a specific item reference, FAC1253022, together with a defined package format of Kraft carton and pallet. Its product details also identify the disc as a flat type and give the A46RBF grade reference.

The second option suits a buyer who wants a broader product page for the same 5-inch format and needs to discuss OEM sizing or branding. Its listing explicitly describes OEM customization as acceptable and gives the same 125 mm, 22.23 mm, 3.2 mm, 22.23 mm bore, 80 m/s, and 12,250 rpm values.

Neither listing creates a dimensional advantage for the other. For routine replacement purchasing, use the first listing when the FAC1253022 reference and package format belong in the order specification. For private-label or customized purchasing discussions, start with the 5-inch reinforced fiberglass metal cut-off disc listing and send the required branding or size details.

Buyer checklist before ordering

• Confirm the grinder accepts a 125 mm disc with a 22.23 mm bore.
• Match the grinder's permitted speed with the 12,250 rpm maximum shown for both options.
• State the required grit, 46# or 60#, and the ferrous-metal application.
• Choose the FAC1253022 reference and package format when that identification is needed.
• Send the target quantity, packaging requirement, and any OEM size or branding request with the quotation inquiry.
