SDS max hammer drill bit Bosch 2608900247 28 x 200 x 320 mm

SDS max hammer drill bit Bosch 2608900247 28 x 200 x 320 mm is a rotary-hammer accessory designed for drilling and light chiselling in concrete and masonry. The bit is shaped for use with SDS max rotary hammers and provides stable drilling performance for creating clean, precise holes in dense building materials. Its reinforced construction helps maintain alignment and reduce breakage during frequent professional use.

Advantages

The SDS max shank ensures secure retention in compatible rotary hammers, minimising play and improving impact energy transfer for efficient material removal. Robust carbide tip geometry and a sturdy flute design promote fast debris evacuation and sustained cutting performance. The length and diameter combination gives a balance between reach and rigidity, suitable for through-holes and deeper anchoring work.

Suitable for

• Drilling holes in reinforced concrete, solid concrete and masonry
• Creating anchor points for bolts and dowels
• Renovation tasks requiring precise depth and clean hole walls
• Light chiselling and chip removal with an SDS max rotary hammer

Key specifications

• Shank type: SDS max compatible
• Diameter: 28 mm
• Working length: 200 mm
• Total length: 320 mm
• Tip: carbide-tipped for concrete and masonry
• Application: rotary hammer drilling and light chiselling in mineral materials

How to use

Install the bit into an SDS max rotary hammer following the tool manufacturer’s insertion procedure until it locks. Select appropriate drilling mode (rotation with hammering) and choose a drill speed and feed pressure suitable for concrete or masonry. Start drilling with steady axial force, avoiding excessive lateral pressure, and allow the hammer action to advance the bit. Periodically withdraw the bit to clear dust and debris from the hole, especially when drilling deeper than the working length. Use appropriate personal protective equipment, including eye, ear and respiratory protection, when operating the rotary hammer.

Usage recommendations

For extended bit life and best results, use the SDS max bit in tools that provide the correct power class for its diameter, maintain consistent drilling pressure, and clear holes frequently. Avoid using the bit as a lever or prying tool, and replace it if the carbide tip shows significant wear or chipping.
