These brushes came with metal bristles and black core. Metal bristles ensure intensive cartridge cleaning.
Its new Design allows an fast and easy Brush exchange.
Brushes with the same properties are also with blue core available. The blue-core metal brush CLMU-A7 is used to distinguish it from the black core one when doing lead-free and leaded soldering.
For gentle cleaning JBC offers the non-metal brushes CLMU-P1 with black core and the CLMU-P7 with blue core.
Brushes supplied in boxes of 2 units.
