11/16 in. X 16 in. x 21-1/2 in. SDS-MAX High-Impact 4-Cutter Carbide Drill Rotary Hammer Bit | DEW-DW5808

DEWALT's 5/8 in. x 16 in. x 21 in. SDS-MAX High-Impact 4-Cutter Carbide Drill Rotary Hammer Bit also incorporates a wear mark indicator to help identify when the bit has reached the point where accurate anchor-hole diameter may no longer be maintained. Its four-flute design helps move drilling debris away from the hole, supporting productive drilling during demanding jobs. The carbide construction and rebar-strike-resistant head make it a practical choice for professional tradesmen as well as DIYers handling structural concrete, block, brick, and similar masonry applications. With a 21-1/2 in. overall length and SDS-MAX compatibility, it is designed for substantial drilling reach without sacrificing the robust construction expected from a heavy-duty rotary hammer accessory.

• The 4-cutter carbide head provides four cutting edges for effective drilling in hard concrete and masonry
• IRON BLAST TECHNOLOGY strengthens the bit to help resist fatigue during demanding drilling applications
• The SDS-MAX shank is designed for use with compatible SDS-MAX rotary hammers
• A wear mark indicator helps determine when the bit may no longer maintain the required hole diameter for anchor installation
• The 16 in. usable length provides substantial drilling depth while the overall length measures 21-1/2 in.
