Bosch Concrete and Masonry Drill Bit Set 4–10 mm (5-piece)

The Bosch Concrete Drill Bit Set HM is a 5-piece collection of carbide-tipped masonry drill bits designed for hard mineral building materials. These bits drill clean holes into solid concrete, masonry, and natural stone. The set suits both DIY applications and professional site work where reliable penetration is needed. Preparing cavities for standard fasteners or carrying out general renovation tasks depends on the durability of the bit head. A tough hard metal (HM) construction resists wear under heavy friction, so operators can rely on the kit for demanding anchoring jobs without rapid bit degradation.

Tool compatibility shapes the design of this collection. Each bit has a classic round shank engineered to seat securely in conventional drill chucks. This universal fit allows the bits to be used directly with standard rotary and hammer drills. Proper seating ensures concentric rotation, helping to keep hole dimensions accurate during aggressive operations. The bits rely entirely on the force of the host tool to break down dense materials, and keeping them firmly locked reduces the risk of slippage when forward pressure is applied against stone.

• 4 mm drill bit for preparing holes for small, lightweight wall plugs.
• 5 mm sizing suits standard household mounting tasks and light fixtures.
• 6 mm bit aligns precisely with standard medium-duty masonry anchors.
• 8 mm option prepares cavities for heavier structural wall fasteners.
• 10 mm bit accommodates large-gauge screws and heavy-duty fixings.
• 140 g total set weight keeps the collection light enough for easy transport in any tool bag.
