The Bosch Expert SDS-max-8X hammer drill bit is engineered for demanding drilling and chiselling tasks in concrete and masonry. Designed to fit SDS-max chucks, this 20 mm diameter bit with a 200 mm working length delivers controlled penetration and reliable performance for deep holes and demolition work. The design focuses on secure bit retention and wear resistance to meet professional construction and renovation requirements.

Advantages

This SDS-max bit offers robust construction and precise geometry for efficient material removal and consistent drilling results. The 20 mm cutting diameter and 200 mm working length enable deep anchoring and through-holes in reinforced concrete and blockwork. Compatibility with SDS-max systems ensures quick bit changes and solid locking during high-impact hammer drilling. Materials and finish are selected to extend service life under heavy-duty use.

Suitable for

• Drilling deep holes in concrete and reinforced concrete
• Heavy-duty masonry drilling and anchoring
• Demolition and chiselling tasks with an SDS-max rotary hammer
• Professional construction and renovation sites requiring durable bits

Key specifications

• Bit type: SDS-max hammer drill bit
• Diameter: 20 mm
• Working length: 200 mm
• Intended materials: concrete, reinforced concrete, masonry
• Use mode: hammer drilling and chiselling with SDS-max rotary hammers

How to use

Insert the SDS-max shank into the rotary hammer's chuck until it locks, then verify secure engagement before starting. Select appropriate drilling speed and hammer setting for concrete, and apply steady pressure without forcing the bit. Withdraw occasionally to clear dust from the hole and maintain cooling. For chiselling tasks, switch to the rotary hammer's chisel mode and position the bit as required; follow the machine manufacturer's safety and operating instructions throughout.

Recommendations

Use appropriate personal protective equipment including eye protection, gloves, and hearing protection. Match the bit diameter and working length to the hole depth and anchor or fixture specifications. Store in a dry place to avoid corrosion and inspect the bit regularly for wear or damage; replace if the cutting edges become rounded or the shank is deformed.
