Rotary Hammer Bosch EXPERT 2608900248 SDS 28 x 400 mm

Bosch EXPERT 2608900248 SDS 28 x 400 mm is an SDS rotary hammer accessory designed for heavy-duty drilling and chiselling in concrete and masonry. The product description identifies it as compatible with 28 x 400 mm SDS shanks and intended for professional applications that require reliable impact performance and secure bit retention. The design supports efficient transfer of hammer energy for deep holes and demanding demolition tasks.

Advantages

The SDS interface ensures fast and secure bit changes and consistent power transfer from the rotary hammer to the bit. The 28 x 400 mm dimensions are suited to reach deeper drilling depths while maintaining stability during impact drilling. The bit's geometry and material selection provide wear resistance under repeated heavy loads, helping to extend service life in professional use.

Suitable for

• Drilling deep holes in reinforced and non-reinforced concrete
• Creating anchor and through holes for installations
• Preparing masonry for mechanical fixings and dowels
• Light chiselling and breakout work when paired with compatible rotary hammer modes

Key specifications

• Shank system: SDS
• Nominal diameter: 28 mm
• Overall length: 400 mm
• Intended material: concrete and masonry
• Use case: impact drilling and light chiselling

How to use

Install the bit into a compatible rotary hammer with an SDS chuck according to the tool manufacturer's instructions, making sure the shank locks securely. Select the appropriate hammer or drill mode for the task and set the correct rotation and impact settings on the rotary hammer. Start drilling at low speed to establish a guide hole, then increase speed and apply steady axial pressure without forcing the bit. For through holes or deep drilling, periodically withdraw the bit to clear dust and reduce heat buildup. When using chiselling functions, use the rotary hammer's dedicated mode and follow safe handling practices.

Usage recommendations

Use suitable personal protective equipment—safety glasses, hearing protection and a dust mask—when drilling concrete or masonry. Match bit diameter and length to the requirement of anchors or sleeves, and allow the bit to cool between intensive cycles to maintain cutting performance.
