Built for the demands of professional electricians and contractors, the Milwaukee® SHOCKWAVE Impact Duty™ Carbide Hammer Drill Bit with POWER TIP™ (Model 48-20-9021) is engineered to outperform standard masonry bits on the toughest job sites. Whether you're drilling anchor points in concrete block, running conduit through brick, or setting fasteners in poured concrete, this 3/8" x 4" x 6" bit delivers up to 9x longer life and 4x faster drilling compared to standard carbide bits — keeping your crew productive and your downtime minimal. The POWER TIP™ geometry reduces walking at start and drives through hard masonry with precision, while the wide flute design clears dust rapidly to reduce heat and extend battery life on cordless rigs. Compatible with both impact drivers and hammer drills, it's the versatile masonry solution every tool bag needs.
