Bosch Silver Percussion Concrete and Stone Hammer Drill Bit Set, 5–8 mm, 3-Piece

The Bosch Silver Percussion Concrete Drill Bit Set (Hammer Drill), 5–8 mm, 3-Piece is a small set of masonry drill bits designed for use with a hammer drill. The bits are made for drilling into solid concrete and stone, working with the percussive action of a compatible power tool to handle the rotational and impact loads involved. They are typically used when preparing bare walls for heavy fixings.

Operating the bits relies on the drill's hammering action to break material ahead of the cutting edge, reducing the effort needed from the user during longer jobs. This compact set suits routine structural repairs where standard rotary bits would wear out quickly. It offers a focused selection of accessories without the bulk of a general-purpose multi-material kit. Both tradespeople and DIY users turn to it for everyday maintenance and property upgrades.

• Includes 5 mm, 6 mm, and 8 mm sizes to fit standard masonry wall plugs.
• Carbide-tipped cutting edges resist wear during high-friction drilling into stone.
• Must be used with a hammer drill to generate the required percussive force.
• Allows secure installation of brackets, anchors, and heavy fittings in solid walls.
• Hammer action breaks up dense concrete without needing excessive manual pressure.
