Diablo Rebar Demon SDS-Max 4-Cutter Hammer Drill Bit, 2 in. x 21 in.

A carbide-tipped SDS-Max hammer bit for boring 2 in. holes through reinforced concrete. Its four-cutter head is made to survive rebar strikes, and it suits contractors running corded or cordless SDS-Max rotary hammers to drill holes for anchor setting.

The DMAMX1400 measures 2 in. x 16 in. x 21 in. Dura-Carbide tips carry up to 2X more carbide and tolerate heat to 1800 F, where ordinary bits give out around 800 F. Tri-Metal bonding keeps the full carbide head in place under heavy impact, and a precision tip keeps holes accurate enough for ANSI anchor setting. An optimized flute clears dust quickly, and a wear mark indicator shows when the bit is no longer cutting to size.
