Bosch Rotary Hammer Bits HCFC2302 SDS Plus 1/4 Inch Hex Drive Bulldog Cutters (4 Flute Carbide Tip Centric Point Concrete Masonry Anchoring)

Bosch SDS-plus® Bulldog™ Hex Drive Rotary Hammer Concrete Screw Anchoring Drill Bits

The Bosch SDS-plus® Bulldog™ Hex Drive rotary hammer drill bits bore precision anchor penetrations across poured concrete slabs, CMU block walls, and structural masonry while interfacing directly with standard screw-anchor installation sleeve assemblies. Engineered with an integrated 1/4-inch hex shoulder on an SDS-plus® shank, these industrial-grade hammer bits eliminate tool changeovers by allowing technicians to drill pilot holes and drive concrete anchor screws using a single installation sleeve and drive collar. Outfitted with Bosch-manufactured wear-resistant tungsten carbide tips, a centric conical centering point that prevents bit wandering on smooth concrete surfaces, an aggressive 4-flute dust extraction geometry that evacuates abrasive masonry debris rapidly to lower operational friction, and high-strength brazed alloy steel body construction, they equip commercial electrical contractors, mechanical installers, and concrete framing crews with 15% faster drilling productivity.

Best Used For:

• Concrete Screw Anchor Installation: Boring pilot holes directly through metal track, electrical conduit clips, and structural brackets into solid concrete using 1/4-inch hex drive sleeve systems.
• CMU Block and Masonry Fastener Mounting: Drilling clean, non-cracking anchor holes in hollow cinder blocks, mortar joints, and solid grout cells for mechanical anchors.
• Hard Aggregate and Rebar-Adjacent Drilling: Penetrating dense poured concrete foundations, parking structures, and precast tilt-up panels containing embedded wire mesh and rebar.

Key Performance & Safety Features

• Integrated 1/4-Inch Hex Shoulder: Designed to fit directly inside standard concrete screw-driving installation sleeves for rapid, seamless drill-and-drive workflows.
• Bosch Tungsten Carbide Tipped Head: Premium carbide formulation delivers maximum wear resistance and maintains edge sharpness under high-impact rotary percussion.
• High-Velocity 4-Flute Geometry: Optimized quadruple-flute spiral clears concrete dust rapidly from the hole, reducing frictional heat and extending bit longevity.
• Centric Conical Centering Tip: Precision-ground guide point ensures dead-on hole placement and prevents bit wandering on polished concrete floors and vertical walls.
• 15% Faster Penetration Speed: Engineered cutting head geometry slices concrete aggregate rapidly, outperforming standard multi-purpose masonry bits.
• High-Temperature Heavy-Duty Brazing: Robust metallurgical bonding secures the carbide tip inside the alloy steel flute body to survive severe rotary torque shocks.

What's Included

• (1) Bosch SDS-plus® Bulldog™ Hex Drive Rotary Hammer Drill Bit (User Selected Model: HCFC2302, HCFC2312, HC2302, HC2312, or HC2341)

Technical Specifications

Pro-Tip: When installing concrete screw anchors, slide your anchor driver sleeve directly over the bit and snap it onto the integrated 1/4-inch hex shoulder immediately after drilling; this locks the driver sleeve securely over the bit for instant fastener driving without unchucking the drill.
