Bosch Rotary Hammer Bit HC2040 1/4 Inch 4 Length Carbide Tip (SDS Plus Masonry Drill Disc Concrete Anchoring Fast Hole Drilling Tool)

Bosch HC2040 Bulldog 1/4" x 2" x 4" SDS-Plus Rotary Hammer Bit

The Bosch HC2040 1/4" x 2" x 4" Bulldog SDS-Plus rotary hammer bit drills precision anchor holes and through-holes in reinforced concrete, masonry, and stone. Engineered with a centric carbide tip for rapid starts and an optimized 4-flute configuration that evacuates dust 15 percent faster than standard S4L bits, this percussion drill accessory maintains cooler operating temperatures under heavy loads. Outfitted with an integrated ANSI wear mark indicator and a heavy-duty shank compatible with all standard SDS-Plus rotary hammers, it equips professional contractors, electricians, and remodelers with jobsite-ready reliability and precise hole geometry.

Best Used For:

• Concrete Anchor and Wedge Installation: Drilling clean, accurate 1/4-inch anchor holes into concrete slabs, foundation walls, and footings for framing brackets.
• Electrical and Mechanical Through-Hole Routing: Piercing masonry block and brickwork rapidly to run conduit, pipes, and anchoring fasteners.
• ANSI-Compliant Jobsite Drilling: Executing high-speed rotary hammer drilling while monitoring bit wear using the built-in depth and tolerance indicators.

Key Performance & Safety Features

• Centric Carbide Tip Design: Advanced tip geometry ensures rapid hole starting, reduced bit walking, and superior circular hole precision.
• 4-Flute High-Speed Dust Evacuation: Optimized flute spiral flushes concrete debris away instantly to keep the carbide tip cool and drilling fast.
• Built-In Wear Mark Indicator: Visual indicator clearly signals when the bit drops below strict ANSI compliance standards for hole sizing.
• Optimized Brazing and Hardening: Proprietary heat-treatment process delivers maximum impact resistance and extended bit longevity in rebar-dense concrete.
• Universal SDS-Plus Shank Interface: Locks securely into all professional corded and cordless SDS-Plus rotary hammer drills.

Technical Specifications

Pro-Tip: When drilling multiple concrete anchor holes with an SDS-Plus hammer bit, let the hammer mechanism do the work without applying excessive forward body pressure; letting the tool hammer naturally prevents premature carbide tip overheating and extends bit life.
