Drill Bit Bosch SDS plus-7X 8mm 115mm

The Bosch EXPERT SDS plus-7X Hammer Bit (8 mm x 115 mm) is a drill bit for SDS plus rotary hammer drills, designed for drilling in concrete, reinforced concrete and hard natural stone. Its Full Carbide Head and Bosch Carbide Technology increase tip durability and resistance to impact, while a reinforced tip connection improves lifetime compared with standard bits.

Advantages

The 4-cutter Full Carbide Head made from a single piece of carbide prevents jamming in rebar and reduces risk of breakage. Bosch Carbide Technology delivers a longer-lasting drill tip and improved wear resistance. A highly resistant welded tip connection enhances durability under heavy-duty use, giving up to three times longer life than a standard drill bit.

Suitable for

• Drilling holes in cured concrete
• Drilling hardened reinforced concrete
• Drilling hard natural stone such as granite and gneiss

How to use

Insert the SDS plus shank into the rotary hammer chuck until it locks. Use the hammer drilling mode and apply steady pressure without forcing the bit. For best results in reinforced concrete, let the carbide head do the work and periodically withdraw the bit to clear dust and debris. Match drilling speed and force to the material—lower speeds for harder stone and higher impact rates for standard concrete.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, ear protection and dust mask). For repetitive professional use, inspect the carbide head regularly and replace the bit when wear affects drilling performance.
