Fein 42498727210 — original Fein "disc" (replacement part)

Keep your Fein magnetic core drill assembly right where it belongs with this genuine Fein disc (part no. 42498727210 / manufacturer number 4 24 98 727 21 0). This small precision disc functions as a spacer/retaining washer in the tool’s assembly and is listed on Fein parts diagrams as "Scheibe" / "Disc."

Example compatible models (illustrative): Fein KBB series (KBB 38 / KBB 38 X) — the part appears in those machines’ exploded parts lists and service drawings as the disc used with the gearbox/holder screws.

What you need to know for the repair: the disc is supplied as a single replacement item and is fitted in the gearbox/holder stack where it acts as a thin spacer under screws or circlips; service documentation shows it installed under the holder/screw locations and calls it out by position in the assembly. When refitting, follow the parts diagram so the disc sits in the correct stack order.

Compact, genuine Fein part intended to restore correct fit and clearances in the original assembly — a straightforward swap when you’re rebuilding or servicing a Fein core drill that lists 42498727210 on its parts diagram.
