Makita 216022-2 — genuine Makita steel ball, diameter 7.0 mm. This precision steel ball is the replacement locking ball used inside the bit/holder assembly of many Makita rotary hammers to help retain the drill/hammer bit; it’s supplied singly so you can replace the worn or missing ball and restore secure bit retention.
Common applications: used in a range of Makita rotary-hammer and SDS-style models — examples include HR2400, HR2410/HR2410 variants, HR3210C, DHR165 and several HR2432/HR2600 series tools (some models use two balls at the bit holder). Verify the exploded parts diagram for your exact model to confirm location and quantity.
Notes: original Makita part number 216022-2; diameter 7.0 mm; sold individually. It installs into the ball seat in the holder — a straightforward swap when replacing a missing or damaged locking ball.
