Bosch Hammer Drill Bit B80034 7/8 Inch SDS Plus Carbide Tipped (10 In Working Depth 12 In Overall Length 2 Cutter Concrete Masonry Boring Tool)

Bosch B80034 7/8 Inch SDS-Plus Carbide-Tipped Hammer Drill Bit

The Bosch B80034 SDS-Plus Hammer Drill Bit functions as a heavy-duty percussion masonry bit engineered to bore clean anchor holes in reinforced concrete, solid block, and hard stone. Built with an industrial-grade two-cutter carbide tip and forged alloy steel, this 7/8-inch (0.875 in.) diameter bit features a 10-inch usable drilling depth and a 12-inch overall structural length. Outfitted with a standardized SDS-Plus slotted shank and right-hand spiral debris-extraction flutes, this bit fits corded or cordless rotary hammers to install structural anchor bolts, threaded rod, and electrical conduit pass-throughs without tip walking or thermal binding.

Best Used For:

• Heavy Concrete Anchor Rod Installation: Boring precise 7/8-inch diameter holes up to 10 inches deep for mechanical wedge anchors and chemical adhesive studs.
• Masonry Block & Brick Utility Penetrations: Drilling clean conduit and piping pass-through holes through structural concrete block, brick, and pour-in-place foundations.
• Commercial Structural Fastening: Executing high-torque rotary hammer drilling routines in hard aggregate stone and concrete slabs.

Key Performance & Safety Features

• Industrial Carbide-Tipped Two-Cutter Nose: Structural-grade carbide tip delivers high impact hardness to drill true cylindrical holes through tough aggregate.
• Standardized SDS-Plus Slotted Shank: Quick-change slotted shank establishes a zero-slip mechanical lock inside all SDS-Plus rotary hammer chucks.
• Pneumatic Percussion-Rated Alloy Steel: Engineered specifically to absorb high-frequency pneumatic hammer impacts without fracturing tool steel or tip braze joints.
• Debris-Clearing Spiral Flute Geometry: Optimized right-hand flute winding continuously extracts abrasive concrete dust and slurry to lower core operating temperatures.
• Extended 10-Inch Usable Drilling Depth: Expansive 12-inch overall length provides up to 10.0 inches of continuous deep anchor boring capacity.

Technical Specifications

Pro-Tip: When drilling deep 10-inch anchor holes in poured concrete with the Bosch B80034 bit, pull the bit back slightly every 2 to 3 inches while keeping the rotary hammer running. This mechanical pulsing motion clears compacted dust accumulation from the spiral flutes, preventing bit binding and maximizing drilling speed.
