Accelerate Masonry Anchoring and Penetration with 5x Extended Service Life

The Bosch HCBG03B25T BlueGranite Turbo™ Carbide Hammer Drill Bit Set is a 25-piece commercial bulk pack of 3/16-inch by 4-inch impact-rated masonry accessories engineered for continuous drilling applications. Designed with an upgraded hex shank configuration, these precision bits integrate natively into high-torque hammer drills and standard impact drivers to handle up to twice the boring speed of conventional masonry components. Each structural bit features an innovative four-grind head matrix that introduces additional cutting angles alongside a multi-grind centering tip, delivering precise, walk-free hole starts across concrete, stone, brick, and block substrates.

Best Used For:

  • Commercial Concrete Anchoring: Boring precise pilot fields into poured concrete pads and structural foundations to receive heavy masonry anchors.
  • Brick and Cinder Block Penetration: Drilling clean, non-binding expansion pathways through structural brick walls, decorative stonework, and hollow cinder blocks.
  • High-Torque Remodeling Operations: Executing high-speed serial penetrations on residential or industrial job sites utilizing high-torque corded or cordless impact tools.

Key Performance & Safety Features

  • Engineered Turbo Carbide Compound: Formulated to supply up to five times the running operational lifetime and wear resistance of standard masonry bits.
  • Advanced Four-Grind Head Geometry: Provides secondary cutting paths to optimize dust extraction, lowering thermal buildup and increasing cutting velocity.
  • Multi-Grind Precision Centering Tip: Implements a razor-sharp mechanical pivot point to prevent bit wandering, ensuring clean tolerances on glossy masonry surfaces.
  • PowerGrip Hex Shank Framework: Eliminates chuck slippage inside high-stress jaws, transferring maximum rotating force directly from the drill spindle to the bit tip.
  • Impact-Rated Core Tempering: Specifically heat-treated to safely withstand the violent, fast rotational kinetic impacts delivered by high-performance professional drivers.

What's Included

  • (25) HCBG03B25T 3/16" x 4" BlueGranite Turbo™ Carbide Hammer Drill Bits
  • (1) Heavy-Duty Industrial Clear Storage Case Compartment Tube

PRO-TIP: When drilling deep anchor pathways into dense stone or poured concrete, apply smooth, firm down-pressure and pull the spinning bit back out slightly every 1/2 inch to clear packed structural dust from the flutes. This prevents thermal compound lock and maximizes the cutting speed of your multi-grind carbide tip.
