Bosch CYL-3 Concrete Drill Bit Set (7-Piece, 4–10 mm)

The Bosch CYL-3 Concrete Drill Bit Set (7-piece, 4–10 mm) gives tradespeople and DIY users a dedicated masonry drilling solution. The carbide cutting heads are designed for abrasive materials, and the bits penetrate hard building materials with consistent results. The set suits concrete, solid brick, natural stone, and limestone. Its main use is creating precise holes for anchors, screws, and other fixings, and the matched range of sizes ensures the correct diameter is available for standard mechanical anchors. The solid carbide construction keeps the cutting edges sharp through repeated use in dense masonry.

Each bit has a two-flute U-shaped design that clears dust from the hole as you drill. This geometry prevents debris from building up, allowing smoother drilling and continued performance through deeper passes into solid blockwork. The bits work with standard rotary drills and impact drivers, both corded and cordless, and the design maintains effectiveness through extended masonry tasks while proper dust clearance helps prevent overheating.

• 4, 5, 5.5, 6, 7, 8, and 10 mm metric sizes to match common wall plugs and masonry anchors.
• Two-flute U-shaped design clears dust from the bore to maintain consistent drilling speed.
• Compatible with corded and cordless rotary drills and standard impact drivers.
• Carbide cutting heads withstand high friction in abrasive stone and concrete.
• Suitable for a broad range of masonry tasks across concrete, solid brick, natural stone, and limestone.
