Bosch HC2051 Sds Plus Rotary Hammer Bit 5/16x4x6 Concrete

Product Description

The ROBERT BOSCH TOOL GROUP HC2051 is a carbide-tipped SDS Plus rotary hammer bit engineered for drilling in concrete and masonry. Measuring 5/16 inches in diameter with a 4-inch working length and 6-inch overall length, this bit is built around a proprietary brazing and hardening process that extends service life under heavy loads. The centric carbide tip geometry initiates holes quickly without wandering, and the improved flute design keeps operating temperatures lower during sustained drilling. A wear indicator mark alerts the user when tip wear has exceeded ANSI specification, preventing undersized holes in critical anchor applications. Licensed electricians, concrete contractors, and general trade professionals are the primary installers.

The HC2051 is suited to through-hole and anchoring applications in concrete, including setting mechanical anchors, adhesive anchor sleeves, and conduit penetrations. The SDS Plus shank is compatible with SDS Plus rotary hammers across the industry. The optimized flute geometry is reported to produce holes approximately 15 percent faster than previous-generation designs, reducing bit changes on high-volume drilling tasks. This bit is appropriate for residential slab work, tilt-up construction, and light commercial concrete applications where consistent hole diameter and bit longevity are priorities.

Key Features

• Carbide tip produced using a proprietary Bosch brazing and hardening process for increased toughness under heavy loads
• Centric tip geometry promotes fast, accurate starts in concrete without bit walking
• Improved flute design reduces heat buildup during continuous drilling cycles
• ANSI wear indicator mark signals when tip wear has reached the replacement threshold
• Approximately 15 percent faster drilling compared to prior-generation Bosch SDS Plus bits
• Optimized for anchoring and through-hole applications in concrete and masonry

Compatibility

Designed for use with SDS Plus rotary hammers. The SDS Plus shank interface is an industry-standard connection compatible with SDS Plus chucks from major rotary hammer manufacturers.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer operation and applicable codes. Confirm the rotary hammer is powered off and disconnected from its power source before inserting or removing the bit from the chuck. Inspect the carbide tip and wear mark before each use and replace the bit when wear exceeds ANSI limits to ensure anchor holes meet minimum diameter requirements. Eye protection and dust control measures are required when drilling into concrete.
