Bosch CYL-5 Concrete and Masonry Drill Bit 8 x 100 mm

The Bosch Blue Granite/CYL-5 Concrete & Masonry Drill Bit 8 x 100 mm is a one-piece tungsten carbide accessory designed for hard building materials. It produces clean holes in abrasive structural surfaces and is suitable for concrete, masonry, natural stone, limestone, and artificial stone. The material composition gives the wear resistance needed for drilling into dense architectural substrates. The bit handles everyday anchoring and installation tasks in standard brickwork. Metal drilling is outside its intended scope, and drilling into reinforced concrete is not recommended for this grade of carbide bit.

The bit inserts directly into standard chucks without needing SDS-plus fitments and is compatible with conventional corded and cordless hammer drills. Its slim profile keeps it manageable when working in restricted spaces. The defined cutting section sets the maximum hole depth before the shaft meets the surface, providing enough reach for typical wall fixings in blockwork. Material removal stays consistent as the drill rotates inside the substrate, with the percussive and rotational forces working together to break through dense building materials.

• 8 mm cutting diameter is precisely sized to match standard masonry wall plugs and anchors.
• 100 mm overall length provides clearance between the drill chuck and the wall surface.
• 50 mm working length sets the maximum hole depth achievable in a single plunge.
• Straight shank fits directly into standard three-jaw corded and cordless drill chucks.
• Two cutting edges deliver controlled material removal and cleaner hole formation during rotation.
