The DIABLO DCX045040X01F is a Type 29 zirconia alumina flap disc designed for aggressive grinding and blending on steel and stainless steel surfaces. Measuring 4.5 inches in diameter with a 7/8-inch X-Lock center hole, this disc mounts directly to angle grinders equipped with an X-Lock spindle interface. The 40-grit coarse abrasive removes material quickly and is well suited for weld seam removal, deburring, and surface conditioning tasks. The plastic backing plate supports the overlapping abrasive flaps and provides consistent flex under load. Fabricators, pipefitters, ironworkers, and sheet metal mechanics are the primary users of this disc.
This flap disc is intended for use on mild steels and stainless steel in both shop and field applications. Its trimmable design allows the operator to expose fresh abrasive as the disc wears, extending usable life during continuous grinding work. The X-Lock arbor hole attachment system provides a tool-free disc change on compatible angle grinders, which reduces downtime in high-volume fabrication and maintenance environments. The 4.5-inch diameter fits standard compact and mid-size angle grinders common in trade work.
Designed for use on X-Lock compatible angle grinders with a 4.5-inch disc capacity. Suitable for grinding and blending applications on steels and stainless steel.
Install and remove this disc only on angle grinders that feature an X-Lock spindle interface. Disconnect the grinder from its power source or remove the battery before changing discs. Confirm the grinder free-speed rating meets or exceeds the 12,000 RPM disc rating before operation. Inspect the disc for cracks or damage before each use and do not use a damaged disc.
