Drill Bits Bosch SDS max-4 2608685862

The Bosch SDS max-4 Drill Bits 2608685862 are designed for heavy-duty drilling in concrete and masonry. Featuring a four-cutter head and a 2-flute U-shaped body, the bit provides long lifetime, reliable dust removal and consistent performance when working in reinforced concrete. The carbide tip increases wear resistance and maintains drilling precision. The shank is compatible with rotary hammers that accept SDS max holders.

Advantages

The four-cutter design reduces jamming on rebar and ensures stable drilling progress, while the U-shaped two-flute geometry improves dust evacuation and further extends service life. A highly durable carbide composition enhances resistance to wear and preserves cutting performance over prolonged use. SDS max shank enables quick, secure fitting in compatible rotary hammers.

Key specifications

How to use

Fit the drill bit into a rotary hammer with an SDS max holder following the tool manufacturer’s instructions. Start drilling at low speed to position the bit, then apply steady pressure and operate at the appropriate hammer/drill setting for concrete or masonry. If hitting rebar, maintain controlled pressure and allow the bit to cut through without excessive force. Clear dust from the hole periodically to sustain drilling efficiency.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) and ensure the rotary hammer and bit are suitable for the hole diameter and material. Replace the bit if cutting performance noticeably decreases or the carbide tip becomes damaged.
