Robert Bosch Tool Group HC2124 Sds Plus Bit 3-pack

Product Description

The ROBERT BOSCH TOOL GROUP HC2124 is a carbide-tipped SDS Plus rotary hammer bit engineered for demanding concrete drilling applications. Measuring 3/4 inch in diameter with a 10-inch working length and 12-inch overall length, this bit features an optimized brazing and hardening process designed to extend service life and deliver faster drilling performance. The centric carbide tip promotes quick starts in concrete while the improved flute geometry allows the bit to run cooler during extended use. A wear mark indicator alerts the user when tip wear exceeds ANSI specification, helping prevent out-of-spec holes on anchoring jobs. Sold in a pack of 3.

This bit is suited for anchoring and through-hole applications in concrete, making it a practical choice for licensed contractors, electricians, plumbers, and HVAC technicians who regularly set anchors or route conduit and pipe through concrete slabs, walls, and masonry. The SDS Plus shank interfaces with standard SDS Plus rotary hammer chucks, making this a direct fit for the most common rotary hammers found on commercial and residential job sites. The Bulldog series design prioritizes durability under heavy intermittent and continuous loads.

Installation Notes

SDS Plus rotary hammer bits are installed and removed by trade professionals without tools using the SDS Plus chuck locking mechanism — always confirm the bit is fully seated and locked before drilling. Wear appropriate eye and hearing protection when operating a rotary hammer in concrete. Inspect the bit for carbide tip damage or wear before each use and retire the bit when the wear mark indicates tip wear beyond ANSI limits. Follow applicable OSHA and job-site safety requirements for concrete drilling and anchor installation.
