Drill bit Bosch SDS plus-7X 25 x 950 mm for rotary hammer drills

The Bosch SDS plus-7X 25 x 950 mm drill bit is designed for use with SDS-plus rotary hammer drills for deep drilling in concrete and masonry. With a 25 mm diameter and an overall length of 950 mm, this bit is intended to create through-holes and long bores in structural materials encountered on construction sites and during renovation work. The SDS-plus shank ensures a secure fit and efficient transmission of percussive energy from the tool to the cutting head, supporting consistent drilling performance in demanding conditions.

Advantages

The drill bit combines a long working length with the SDS-plus connection to enable deep, straight drilling without frequent extension. Its carbide-tipped cutting head and robust flute geometry are engineered to resist wear and to evacuate dust and debris effectively from deep holes. The hardened shank and precise fit reduce play in the chuck, improving accuracy and tool life when used with compatible rotary hammers.

Suitable for

• Drilling through concrete walls and slabs
• Creating deep anchor or conduit holes on construction sites
• Structural renovation requiring long, straight bores
• Tasks in masonry, blockwork and reinforced concrete where extended reach is needed

Key specifications

• Diameter: 25 mm
• Total length: 950 mm
• Shank type: SDS-plus
• Intended material: concrete and masonry
• Cutting head: carbide-tipped

How to use

Install the SDS-plus shank into the rotary hammer‘s chuck until it locks securely. Select the rotary hammer’s hammer drilling mode and position the bit perpendicular to the work surface. Start drilling at low speed to establish the bore, then apply steady pressure while allowing the tool to deliver impact energy; avoid excessive axial force that can cause bit bending or tool overload. Periodically withdraw the bit to clear dust from the hole and improve dust evacuation, especially during deep drilling operations. Ensure the rotary hammer is compatible with SDS-plus bits and rated for long bits of this size.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. For reinforced concrete, maintain controlled advance and clear debris frequently to prevent overheating and premature wear of the carbide tip. When drilling long through-holes, consider using a guide or laser alignment to keep the bore straight and use a vacuum or dust extraction adapter if available to reduce onsite dust.
