Drill Bits Bosch SDS max-4 2608685866

The Bosch SDS max-4 Drill Bit (MPN 2608685866, EAN 3165140564175) is a heavy‑duty masonry bit designed for rotary hammers with SDS‑max holders. It features a 4‑cutter head and a 2‑flute U‑shaped body made from highly durable carbide to resist wear during drilling in concrete and masonry. The combination of the four‑cutter geometry and optimized flute profile reduces jamming on rebar, improves dust evacuation and extends service life.

Advantages

The four‑cutter head provides consistent cutting performance and reduces the risk of jamming when encountering rebar. The 2‑flute U‑shape enhances dust removal for cleaner holes and less friction. Carbide construction increases resistance to wear and prolongs bit lifetime under heavy use. The bit is compatible with all SDS‑max rotary hammers, offering straightforward interchangeability for professional applications.

Suitable for

• Drilling holes in reinforced concrete
• Drilling in masonry and brick
• Heavy‑duty construction and renovation work
• Use with SDS‑max rotary hammers

How to use

Install the bit into an SDS‑max rotary hammer according to the tool manufacturer's instructions. Select the hammer or rotary‑hammer mode appropriate for drilling into concrete or masonry, apply steady axial pressure and allow the tool to do the cutting. Withdraw the bit periodically to clear dust when drilling deep holes; use appropriate safety equipment (eye protection, hearing protection and dust mask) and follow on‑site safety rules.

Usage recommendations

For improved bit life and hole quality, start with a small pilot hole when precise positioning is required, avoid excessive side pressure, and remove dust regularly during deep drilling. Use with compatible SDS‑max rotary hammers and appropriate PPE.
