6 pc. SDS-plus® Bulldog™ Tough Rotary Hammer Bit Set

The Bosch SDS-plus® Bulldog™ Tough Rotary Hammer Bit Set (HC4ST006) is a 6-piece kit designed for high-performance drilling and chiseling in concrete, reinforced masonry, and tough substrates. It features Bosch’s four-cutter carbide-tipped head design, delivering up to twice the lifespan in concrete with rebar compared to standard two-cutter bits. The optimized four-flute geometry removes dust efficiently, reduces heat buildup and helps maintain drilling speed. Bosch-made carbide ensures durability under heavy loads, while the SDS-plus® shank ensures secure, high-impact transfer in compatible rotary hammers. The kit includes 5/32" × 4" × 6", 3/16" × 4" × 6", ¼" × 4" × 6", ⅜" × 4" × 6" bits, plus a flat chisel and a point chisel — all packaged in a durable case for convenient job-site organization. Ideal for contractors tackling anchoring, through-hole drilling and general rotary hammer tasks, this set brings high durability and versatility to heavy-duty applications.
