Drill bit set Bosch 2 608 578 765, 11 pcs, for rotary hammer, for concrete

Bosch drill bit set 2 608 578 765 comprises 11 carbide‑tipped masonry bits engineered for use with rotary hammers and intended specifically for drilling in concrete. The set includes a range of common diameters for anchoring, dowel installation and through‑hole drilling tasks on construction and renovation sites. Each bit features SDS plus compatibility for quick tool engagement and reliable power transfer when used with compatible rotary hammer models.

Advantages

The tungsten carbide cutting plate with two cutting edges increases wear resistance and maintains drilling performance in abrasive concrete. The two‑flute U‑shaped flute geometry improves dust extraction from the hole and reduces clogging during continuous drilling. Compatible with SDS plus tool holders, the bits enable secure mounting and efficient energy transmission for percussive drilling in hard masonry. The set format provides multiple sizes for a variety of fixing and anchoring jobs, reducing the need to change tools on site.

Suitable for

• Drilling anchor and dowel holes in reinforced and non‑reinforced concrete
• Through‑hole drilling for pipes and conduits in concrete walls and floors
• General masonry drilling during construction and renovation

Key specifications

• 11 pieces covering a range of commonly used diameters for concrete fixing work
• SDS plus shank for compatibility with SDS plus rotary hammers
• Tungsten carbide 2‑cutter plate for increased tip hardness and wear resistance
• 2‑flute U‑shape flute design for effective dust removal
• Optimised geometry for percussive drilling in concrete

How to use

Fit the appropriate drill bit into the rotary hammer’s SDS plus chuck until it locks. Select the hammer drilling mode on the tool and start drilling at low speed to create a pilot point, then increase pressure and maintain steady forward force; avoid excessive lateral force. Withdraw the bit periodically to clear dust from the hole and allow the bit to cool. Use correct drill diameter and depth stops or collars when installing anchors or dowels to ensure proper fit.

Usage recommendations

Use personal protective equipment including safety glasses, dust mask and hearing protection. Match drill speed and hammer settings to material hardness, and allow pauses during extended drilling to prevent overheating of the carbide tip. Replace worn bits to maintain clean, accurate holes and safe working conditions.
