Cordless Carbon Brush Set - 194427-5 CB440

195021-6 supersedes older part numbers: 194427-5

Original Makita carbon brush set CB‑440 (part 195021‑6) — a direct replacement brush set for Makita brushed motors; replaces older Makita references such as 194427‑5 and 194159‑4.

What’s included and key dimensions: two carbon brushes per pack with braided copper wire leads and springs attached for an easy swap. Each brush measures approximately 3 × 10 × 13 mm (thickness × width × length). The brushes are graphite/carbon with brass terminal/lead construction.

Example models this CB‑440 set fits (common examples only): BDF452 / BDF451 / BDF440 series drills, BHP451 / BHP452 hammer drivers, BTD130 / BTD140 / BTD142 impact drivers, BTP140, BTW250 / BTW251 impact wrenches, DDF482 / DHP482 and DTW250 / DTW251 among many other Makita LXT 18 V brushed motor tools. (Check the brush size against your tool’s existing brushes to confirm fit.)

Why install this part: worn brushes cause poor performance, excessive sparking and can damage the commutator — replacing them with an original Makita CB‑440 carbon brushes restores motor contact and extends tool life. The set is ready to drop in where CB‑440 is specified.

(If your tool’s brush compartment or terminal style looks different, compare the 3 × 10 × 13 mm dimensions and the wire‑lead/spring arrangement to be sure this is the correct brush set for your model.)
