Drill bit MEGA SDS+ 8 mm, model 80835, SDS+ shank for rotary hammer drills

MEGA SDS+ 8 mm drill bit, model 80835, is a rotary-hammer accessory designed for drilling 8 mm diameter holes in concrete, masonry and common building materials. The bit features an SDS+ shank for secure engagement in SDS+ compatible rotary hammers, allowing quick insertion and removal while maintaining stable rotation and impact transfer. It is intended for routine site and installation tasks where small-diameter anchor, dowel or through-holes are required.

Advantages

The SDS+ shank ensures a reliable fit in compatible rotary hammers, reducing slippage and improving energy transfer from the tool to the cutting head. The 8 mm diameter provides a balance between speed and control for small anchors and fixings. The bit is suitable for repeated use in typical construction conditions and allows faster bit changes compared with threaded or straight-shank solutions.

Suitable for

• Drilling 8 mm holes for wall plugs, anchors and dowels in concrete and masonry
• Installing small fixtures, light fittings and cable clips on building sites
• General-purpose site drilling where an SDS+ bit is required

Key specifications

• Tip diameter: 8 mm
• Shank type: SDS+ shank for rotary hammers
• Suitable materials: concrete, masonry and common building materials
• Application: percussion drilling with SDS+ compatible rotary hammers

How to use

Install the drill bit by inserting the SDS+ shank into the rotary hammer’s chuck until it locks. Select the hammer-drill (percussion) mode on the tool and set an appropriate speed for 8 mm drilling in concrete or masonry. Apply steady axial pressure, allowing the tool’s percussion action to advance the bit; avoid excessive force that could cause bit breakage. Retract periodically to clear dust from the hole for consistent drilling progress and longer bit life.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask. For harder concrete or reinforced areas, start with a pilot position and consider using a lubricant or lower feed pressure only if recommended by the rotary hammer manufacturer. Inspect the bit before use for wear or damage and replace if the cutting tip is blunted or the shank is deformed.
