Bosch HCFC2051 Sds-plus Rotary Hammer Drill Bit 5/16 in

Product Description

The ROBERT BOSCH TOOL GROUP HCFC2051 is a carbide SDS-Plus rotary hammer drill bit from the Bulldog Xtreme line, measuring 5/16 inches in diameter with a 4-inch flute length and 6-inch overall length. Built for heavy-duty rotary hammers, it uses Diffusion Bonding Technology to create a stronger carbide-to-steel bond, resulting in extended service life compared to standard SDS-Plus bits. It delivers four times longer life in rebar and 40 percent more life in concrete than competitive full head carbide bits. Licensed HVAC and plumbing rough-in crews, electricians, and concrete drilling tradespeople who regularly core through rebar-reinforced slabs will find this bit reduces changeout frequency and downtime on the job.

This bit is suited for residential and commercial concrete drilling applications where rebar encounters are frequent. The centric conical tip guides the bit through concrete to produce rounder, more accurate holes. The integrated wear mark lets the operator confirm hole diameter accuracy without stopping to measure. It is optimized for use in heavy-duty SDS-Plus rotary hammers and performs across standard concrete, block, and rebar-reinforced substrates.

Key Features

• Diffusion Bonding Technology creates a stronger carbide bond for extended bit life
• Four times longer life in rebar compared to standard SDS-Plus bits
• 40 percent more concrete life than competitive full head carbide bits
• Centric conical tip guides bit through concrete and produces rounder holes
• Wear mark indicates accurate hole diameter throughout the life of the bit
• No-jam design resists locking up when the bit contacts rebar

Compatibility

Designed for use with heavy-duty SDS-Plus rotary hammers. The SDS-Plus shank is a widely accepted standard across professional-grade rotary hammer platforms used in concrete and masonry drilling.

Installation Notes

Installation of this bit requires an SDS-Plus compatible rotary hammer; do not attempt to use it in a standard keyed or keyless chuck drill. Always wear appropriate eye and hearing protection when drilling into concrete or masonry. Power down and disconnect the tool before inserting or removing the bit. Follow applicable OSHA silica dust control guidelines when drilling concrete, including use of water suppression or vacuum extraction as required by site conditions.
