Bosch Silver Percussion CYL-3 Concrete Drill Bit 5 x 85 mm

The Bosch Silver Percussion CYL-3 Hammer Drill Bit 5 × 85 mm is a 1-piece masonry and concrete drill bit engineered for hard mineral building materials. It is rated for structural applications requiring sustained hammer drilling in concrete. The bit transfers rotational and percussive force into the substrate to produce clean masonry penetration. Used correctly, it creates precise holes for heavy-duty anchors, wall plugs, and mounting brackets in solid masonry and concrete. The cutting geometry supports controlled material removal, and the bit withstands the high-stress percussive action typical of demanding drilling work.

The bit is driven by an external power tool and channels rotational and impact energy directly into the work surface. Its geometry is shaped for the clean, accurate holes required by standard masonry fixings, so users can reach the necessary depth without chipping or spalling the surrounding material. The flutes are designed for aggressive dust clearance through heavily compacted concrete, and the overall construction supports steady progress during prolonged drilling.

• 5 mm drill bit diameter creates appropriately sized holes for standard wall plugs and anchors.
• 85 mm overall length provides sufficient reach for recessed structural areas.
• 50 mm working length sets the maximum active cutting depth before surface interference.
• 2 cutting edges support steady material removal and consistent dust clearance in hard concrete.
• Straight shank format ensures direct fit with standard keyed and keyless drill chucks.
