从China供应商批发进口4" T27 Grinding Disc Grinding Wheel For Metal — FOB条款

This 4" T27 grinding disc is a resin-bonded, type 27 depressed-center wheel designed for aggressive grinding on metal surfaces. The listed configurations include 100x4x16 mm (4" x 1/6" x 5/8"), 100x6x16 mm (4" x 1/4" x 5/8"), with abrasive type A (aluminum oxide), grit sizes of 46 or 30, and hardness grade Q. Maximum rotational speed is 15,200 RPM for the 4" variants, with packaging quantities of 280 or 200 pieces per carton as specified.

Aluminum oxide abrasive is standard for carbon steel, tool steel, and cast iron applications, offering a balance of hardness and friability for efficient material removal. Grit 46 provides a coarser cut for rapid stock removal, while grit 30 is finer for intermediate finishing; both are typical for industrial metal grinding. The depressed-center design allows the disc to be mounted on portable angle grinders, with the 5/8" arbor fitting most standard tools.

Primary uses include grinding welds, cleaning burrs and rust, and surface polishing in metal fabrication, shipbuilding, and maintenance workshops. Buyers typically source these in bulk for high-volume operations, with packaging optimized for logistics. Confirm compatibility with your grinder’s arbor size and maximum RPM rating before ordering, as operating beyond the specified speed voids safety guarantees.
