Hammer drill bit Bosch SDS Plus-5 — 8 mm, for rotary hammer and drilling

Bosch Hammer drill bit SDS Plus-5 — 8 mm is a single 8 mm masonry hammer drill bit designed for use with rotary hammers featuring SDS Plus chucks. Intended for impact drilling in concrete and masonry, this drill bit is supplied as one piece and is suitable for repair, installation and construction tasks that require precise hole making for anchors and fixings. The design includes features to support accurate starts and to monitor wear during repeated use.

Advantages

The SDS Plus-5 drill bit provides guided starts and stable drilling behavior thanks to a centring tip that reduces jarring and wandering when initiating holes. Manufacturing methods that combine brazing and hardening increase tip durability while reducing vibration transferred to the user. A visible wear mark helps assess whether hole diameter remains within tolerance for metal anchors. Bosch quality standards and PGM test marking ensure consistent performance for typical masonry applications.

Suitable for

• Drilling holes in concrete and masonry for anchors and fixings
• Repair and renovation work requiring impact drilling
• Installation tasks such as mounting frames, fixtures and fittings
• Construction site drilling where SDS Plus rotary hammers are used

Key specifications

• Shank type: SDS Plus compatible
• Drill diameter: 8 mm
• Intended material: concrete and masonry
• Pack quantity: 1 piece
• Manufacturing highlights: brazed and hardened tip, centring tip, wear mark for diameter check

How to use

Secure the drill bit in an SDS Plus chuck of a compatible rotary hammer, ensuring it locks into place. Mark the drilling position and start at low speed to let the centring tip establish the hole without wandering. Apply steady pressure and allow the hammer action to do the cutting; avoid excessive force which can accelerate wear. Periodically withdraw the bit to clear dust and check the wear mark to confirm the hole diameter remains within tolerance for anchor installation.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask and hearing protection) and follow the rotary hammer manufacturer’s safety instructions. For best results in reinforced concrete, use progressive drilling and clear debris frequently. Replace the drill bit when the wear mark indicates the diameter is out of tolerance to ensure secure anchor holding.
