Rotary hammer drill bit Bosch SDS plus-7X 16 x 400 mm (2608900133)

Bosch SDS plus-7X 16 x 400 mm rotary hammer drill bit is engineered for deep drilling in concrete, masonry and natural stone with SDS-plus rotary hammers. The 16 mm diameter and 400 mm overall length allow drilling through thick materials or making blind holes at depth while maintaining compatibility with Bosch SDS-plus chucks. The bit is designed for stable retention in the chuck and sustained performance during repetitive professional and DIY drilling tasks.

Advantages

The SDS plus-7X geometry provides improved chip removal and reduced jamming when drilling deep holes, while hardened carbide tip construction increases wear resistance and edge retention. The shank is designed for secure engagement with SDS-plus chucks, minimizing slippage under impact load. The extended length offers access to recessed areas and enables drilling of through and blind holes without changing to extensions.

Suitable for

• Drilling deep holes in reinforced or non-reinforced concrete
• Making anchor and through holes in masonry and brick
• Creating installation channels in natural stone and blockwork
• Professional and home renovation tasks requiring extended reach

Key specifications

• Shank type: SDS-plus compatible shank for rotary hammer chucks
• Diameter: 16 mm
• Overall length: 400 mm
• Tip material: carbide-tipped cutting head for enhanced wear resistance
• Intended material: concrete, masonry, natural stone, brick
• Suitable hole type: through and blind holes

How to use

Mount the drill bit into an SDS-plus rotary hammer according to the tool manufacturer's instructions, ensuring the shank is fully engaged in the chuck. Select appropriate rotation and impact settings for the material being drilled. Start drilling at low speed to establish the pilot entry, then increase to recommended operating speed while maintaining steady pressure. Periodically withdraw the bit to clear debris and prevent overheating. For reinforced concrete, use controlled feed and avoid excessive lateral force to protect the carbide tip.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask. For best results, match drill speed and hammer settings to the material hardness and allow the bit to cool by pausing on long or continuous drilling operations. Replace the bit when signs of excessive wear or reduced cutting performance appear to maintain drilling efficiency and safety.
