Makita B-64428 SDS-Max rotary hammer drill bit with dust extraction 16x400/600

SDS-MAX drill bit with holes in the cutting head and a vacuum connection in the shank for highly efficient dust extraction, eliminating the need for traditional flutes. When connected to a vacuum, the bit stays cool and debris is removed efficiently through the holes in the bit. These features make the bit longer-lasting, especially when drilling hard stone materials.
