Drill bits Bosch SDS max-4 2608685877, 4-cutter design, 16 mm diameter

Bosch SDS max-4 2608685877 drill bit, 16 mm diameter, is an SDS‑max shank accessory developed for rotary hammers to drill concrete and masonry. The four‑cutter head geometry improves drilling efficiency by optimising chip removal and reducing vibration during operation. It is intended for tasks that require controlled, fast penetration into hard substrates and consistent hole quality.

Advantages

The 4‑cutter design ensures more even contact with the work surface, leading to smoother drilling and reduced walking at startup. Optimised flute geometry promotes efficient evacuation of dust and debris from the hole, which maintains drilling speed and reduces heat build‑up. The SDS‑max shank provides secure retention and rapid bit changes in compatible rotary hammers, improving on‑site productivity.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Making openings in masonry and brickwork
• Preparing holes for electrical and plumbing installations in solid substrates
• Professional construction and renovation tasks requiring repetitive drilling

Key specifications

• Shank type: SDS‑max compatible shank for rotary hammers
• Cutting geometry: 4‑cutter head for balanced contact and improved chip removal
• Tip diameter: 16 mm nominal drilling diameter
• Intended material: concrete, masonry and similar hard substrates
• Primary function: percussion drilling with rotary hammer tools

How to use

Select a compatible rotary hammer with an SDS‑max chuck and fit the drill bit by inserting the shank until it locks into place. Use the appropriate hammering and rotation mode for the substrate: enable percussion mode for concrete and masonry. Apply steady axial pressure without forcing the bit; allow the tool and cutter geometry to remove material. Withdraw the bit periodically to clear dust and prevent clogging, and avoid prolonged idle contact with the bit tip to reduce wear.

Usage recommendations

Wear appropriate personal protective equipment such as safety goggles, hearing protection and dust mask when drilling. Use a dust extraction system or intermittent drilling to minimise airborne dust. Match drill speed and hammering force to the substrate and replace the bit when cutting performance or hole quality declines.
