Bosch 2 609 255 416 borr 3 st

The Bosch 2609255416 drill bits are a set of three masonry bits engineered for drilling into concrete and other hard mineral materials. Constructed for durability, each bit combines a stable shank with a carbide tip to withstand repeated impact while maintaining drilling accuracy. The set is intended to provide reliable performance for tasks that require precise holes in dense substrates.

Advantages

These drill bits offer a combination of wear-resistant tip geometry and a robust body designed to resist bending and breakage during heavy-duty use. The carbide cutting edges help retain sharpness over prolonged use, while the consistent shank diameter ensures secure chuck gripping and minimal runout. The three-piece set provides size flexibility for various hole dimensions without compromising bit stability.

Suitable for

• Drilling holes in concrete, brick and masonry
• Anchoring bolts and plugs in structural and non-structural walls
• Installing electrical boxes, conduit and plumbing fixings
• General renovation and construction drilling tasks

Key specifications

• Set size: 3 pieces
• Intended material: concrete, brick, masonry
• Tip material: carbide for increased wear resistance
• Shank type: straight cylindrical shank compatible with standard chucks
• Design: masonry-style flute geometry for efficient dust removal

How to use

Use these masonry drill bits with a hammer drill or rotary hammer set to the appropriate mode for concrete. Mark the drilling point, start at low speed to create a pilot indentation, then apply steady pressure while allowing the tool's percussive action to do the work. Periodically withdraw the bit to clear accumulated dust from the hole and avoid excessive heat buildup. Replace the bit if the cutting edge becomes visibly worn or if drilling performance declines.

Recommendations

For best results, select drill speeds and hammer settings suitable for the workpiece and maintain a perpendicular drilling angle. Wear appropriate personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry. Use suitable anchors and follow manufacturer instructions for fixtures and fastenings to ensure secure installations.
