Bosch HC2122 Sds Plus Rotary Hammer Bit 3/4x6x8 3 Pack

Product Description

The ROBERT BOSCH TOOL GROUP HC2122 is a carbide-tipped SDS Plus rotary hammer bit engineered for drilling in concrete and masonry. Measuring 3/4 inch in diameter with a 6-inch working length and 8-inch overall length, this bit ships in a pack of three. The centric carbide tip is manufactured using an optimized brazing and hardening process that increases durability under heavy loads. An improved flute design reduces heat buildup during operation, and a proprietary Bosch hardening process extends bit life, delivering more holes per bit compared to standard alternatives. A built-in wear mark alerts the installer when the tip has worn beyond ANSI specification.

This bit is suited for residential and light commercial concrete drilling applications. It is designed for anchoring and through-hole work in concrete slabs, walls, and foundations. The centric tip geometry promotes quick starts on concrete surfaces without walking, making it practical for repetitive anchor-setting tasks on the jobsite. Licensed electricians, plumbers, HVAC technicians, and general contractors who require precision holes for fastener placement will find this bit appropriate for their rotary hammer equipment.
