7/8 in. x 16 in. x 21-1/2 in. SDS-MAX High-Impact 4-Cutter Carbide Drill Rotary Hammer Masonry Bit | DEW-DW5816

DEWALT's 7/8 in. x 16 in. x 21-1/2 in. SDS-MAX High-Impact Carbide 4-Cutter Rotary Hammer Bit provides a 16 in. usable drilling length and 21-1/2 in. overall length for deeper concrete and masonry applications. A four-cutter carbide head helps maintain hole geometry while providing greater resistance to wear, and the wear-mark indicator helps identify when the bit has reached its replacement point for accurate anchor-hole sizing. Variable-helix flutes assist with efficient dust removal during drilling, while the durable construction is intended for professional construction, installation, and renovation work.

• Iron Blast Technology strengthens the bit to help resist fatigue during demanding drilling applications
• A full-carbide four-cutter head provides durability and helps maintain consistent hole geometry
• The carbide cutting head is designed to withstand occasional rebar strikes
• A wear-mark indicator helps identify when the bit may no longer produce an accurate anchor hole
• The SDS-MAX shank is designed for use with compatible SDS-MAX rotary hammer drills
