DeWalt 583890-00 — Genuine DeWalt hardened steel ball (7.0 mm)
Description:
A genuine DeWalt hardened steel ball (part number 583890-00) used in SDS rotary/hammer drills. The 7.0 mm diameter steel ball sits in the spindle/hammer mechanism to locate and retain the bit and to transfer impact forces reliably; it’s supplied as the single replacement ball and fits into the bit-retaining assembly. Replace it when pitting, flat spots, or bit play appears to restore secure bit engagement and smooth hammer action.
Example compatible models :
DCH273, DCH273B, DCH293, DCH263P2, D25033, D25134, D25123K, D25203K, D25324K, D25416K. These are typical DeWalt rotary/hammer models that use the same ball in the spindle/hammer assembly.
Notes:
- Sold individually as the original DeWalt part 583890-00 and sized to the factory tolerance for a direct fit.
- Simple field replacement requires partial disassembly of the nose/spindle—refer to your tool’s parts diagram or manual for the exact removal/reassembly steps.
If you need this exact component to restore proper bit retention and hammer action, this genuine DeWalt 583890-00 ball is the precise replacement used in the models listed above.
