Drill bit Bosch Expert SDS‑max‑8X 14 mm diameter, 940 mm length

The Bosch Expert SDS‑max‑8X 14 mm diameter, 940 mm length drill bit is designed for SDS‑max rotary hammers to drill deep holes in concrete and masonry. It provides an extended reach for anchoring, through‑drilling and installations where standard‑length bits are insufficient. The fluted design and carbide tip are optimized for effective dust removal and sustained drilling performance in demanding construction and renovation environments.

Advantages

This drill bit offers a long overall length of 940 mm that enables deep and hard‑to‑reach drilling without the need for extensions. The SDS‑max shank ensures secure coupling with compatible rotary hammers for consistent power transfer and reduced slippage. The carbide tip maintains cutting performance and wear resistance when working with concrete, reinforced concrete and masonry. The flute geometry aids chip evacuation, improving drilling speed and reducing blockages during prolonged use.

Suitable for

• Drilling deep anchor holes in concrete and masonry
• Through‑drilling for pipes and conduits
• Installation tasks in construction and renovation requiring extended reach

Key specifications

• Shank type: SDS‑max compatible
• Diameter: 14 mm
• Overall length: 940 mm
• Tip material: carbide
• Intended material: concrete, reinforced concrete, masonry

How to use

Fit the SDS‑max shank securely into a compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling position, use appropriate personal protective equipment, and start at low speed to position the bit before applying steady pressure. Use intermittent withdrawal to remove debris and allow dust extraction if available. When drilling reinforced concrete, maintain control of the tool to prevent bit deflection and avoid overheating by allowing pauses during continuous drilling.

Usage recommendations

Use with a rotary hammer that supports SDS‑max bits and match the bit diameter to the required anchor or conduit size. For best results, combine with a dust extraction system and replace the bit when carbide wear leads to slower penetration or increased vibration.
