The Diablo DPB300XCCC01F 3 Inch X-LOCK Carbon Steel Crimped Cup Brush is a wire cup brush made for X-LOCK angle grinders. This is a cup brush designed for surface preparation, weld cleanup, deburring, and polishing on metal surfaces. Model Number: DPB300XCCC01F. If you already run an X-LOCK grinder and want faster accessory changes without messing with a traditional lock nut setup, this is the point of this accessory.

The big draw here is the X-LOCK mount. Diablo states it delivers up to 5 times faster wheel changes versus a standard angle grinder mount, and it does that without extra parts. On the job, that matters when you are switching between grinding, brushing, and finishing tasks instead of burning time hunting for flanges, nuts, or a spanner wrench.

The 3 inch diameter makes this metal cleaning accessory a good fit for controlled prep work where you want access and maneuverability instead of a large footprint. The crimped carbon steel wire is a solid choice for removing base coatings before new coatings go on, cleaning up bead welds, and knocking down burrs. Crimped wire is typically the better call when you want a useful balance of cleaning action and control for general-purpose metalworking.

This Diablo cup brush is specifically designed for the X-LOCK portable tool platform, so the fit and attachment method are part of the product, not an afterthought. Snap it on, get to work, and pull the grinder lever to release it when you are done. That straightforward setup is especially useful for fabrication shops, maintenance crews, and contractors who change accessories several times in the same task.

In practical use, this accessory is best for prep and cleanup rather than heavy stock removal. Use it to strip coatings, clean weld areas, and prep metal for finishing or repainting. If your work is mostly steel surface prep and general cleanup with an angle grinder, the shape, wire style, and X-LOCK interface all line up well for that job.

Who should buy it? Metalworkers, welders, maintenance techs, and serious DIY users already invested in X-LOCK grinders. If you do not have an X-LOCK grinder, this is not the right brush. If you do, the Diablo DPB300XCCC01F 3 Inch X-LOCK Carbon Steel Crimped Cup Brush is a simple time-saver that makes routine metal prep less of a hassle.
