Makita Concrete Drill Bit 8 x 110 mm (D-05290)

This single-piece Makita concrete drill bit has an 8 mm diameter and a tungsten carbide tipped (TCT) head. It is designed for hard building materials and resists wear on abrasive surfaces. The bit drills directly into stone, concrete, brick, concrete block, and lightweight concrete. It works effectively with a standard impact drill to prepare holes for wall anchors. Operators rely on this size to produce accurate openings across a range of structural tasks.

The bit has a standard cylindrical shank for compatibility with conventional three-jaw drill chucks. A built-in centering point positions the tip accurately before the drill fully engages. The flute geometry along the shaft continuously clears dust to prevent binding. Its design keeps the bit stable under the high-vibration loads produced by impact mechanisms. Consistent trajectory control delivers straight channels for secure fastener installation.

• 110 mm overall length provides sufficient reach for thick masonry.
• 60 mm maximum working length sets the deepest functional bore for wall plugs.
• 7 mm shank diameter fits securely in non-SDS chucks without an adapter.
• 2 distinct cutting edges fracture stone and brick for steady material removal.
• 40 g overall weight reduces added fatigue when operating the drill.
