Description

Drill Faster and Anchor Securely in Hard Masonry

Maximize your productivity on the job site with the Bosch BlueGranite Turbo™ Hammer Drill Bit (HCBG03T). Designed for professional tradespeople, this 3/16-inch bit sets a new standard for masonry drilling, delivering up to 5X longer life and 2X faster speed than standard bits. The advanced 4-grind carbide head features two additional cutting angles that aggressively pulverize concrete, block, and stone, while the multi-grind centering tip ensures precise, non-slip starts every time. This means you can drill more holes per charge and finish your fastening tasks significantly faster.

Engineered for high-torque applications, the HCBG03T features a robust PowerGrip hex shank that positively locks into the chuck. This eliminates bit slippage and makes the bit fully compatible with both standard hammer drills and impact drivers. The milled U-flutes with deep-cut spirals efficiently channel dust and debris out of the hole to prevent clogging and overheating. Whether you are installing 1/4-inch concrete screws or standard anchors, this impact-rated bit provides the durability and speed required for heavy-duty construction work.

Key Features

  • Turbo Speed: Delivers 2X faster drilling and 5X longer life compared to standard masonry bits.
  • PowerGrip Shank: Aggressive hex shank prevents slippage and allows for use in impact drivers.
  • Precision Starts: Multi-grind carbide centering tip prevents skating for accurate hole placement.
  • Advanced Geometry: 4-grind head provides aggressive cutting angles to break down masonry materials quickly.
  • Dust Ejection: Milled U-flutes with deep spirals rapidly remove dust to keep the bit running cool.
  • Impact Rated: Robust head construction withstands the high torque of impact drivers.
  • Durable Carbide: Bosch-made carbide tip ensures outstanding wear resistance under heavy loads.

Pro-Tip: This 3/16-inch bit is the standard size required for piloting holes for 1/4-inch concrete screws (such as Tapcons). After drilling your hole to the required depth, be sure to run the bit in and out of the hole a few times while spinning to clear residual dust. This ensures the screw threads bite fully into the concrete for maximum holding power.
