Drill bit MEGA SDS+ 8 mm for concrete, model 80821

MEGA SDS+ 8 mm drill bit for concrete, model 80821, is an SDS+ shank rotary hammer accessory designed for drilling 8 mm diameter holes in concrete, brick and other masonry materials. The bit features a carbide tip geometry and flute design that support efficient dust removal and stable penetration when used with compatible SDS+ rotary hammers. It is intended for common anchoring and conduit installation tasks where precise 8 mm holes are required.

Advantages

The drill bit offers consistent hole diameter and straight drilling thanks to a reinforced tip profile and optimized flute for removing debris. Compatibility with SDS+ chucks ensures quick bit changes and secure retention during rotary hammer operation. The carbide cutting edge enhances wear resistance during repetitive drilling in abrasive concrete and masonry surfaces.

Suitable for

• Drilling 8 mm holes in concrete and structural masonry
• Installing anchors, dowels and sleeve anchors
• Creating passages for small conduits and cable routing
• Preparation of mounting points for fixtures and fittings

Key specifications

• Drill diameter: 8 mm
• Shank type: SDS+ compatible
• Intended material: concrete, brick and general masonry
• Tip material: carbide cutting edge for improved wear resistance
• Design features: fluted body for dust evacuation and stable drilling

How to use

Select an SDS+ rotary hammer that supports 8 mm accessories and secure the MEGA SDS+ 8 mm drill bit into the chuck following the tool manufacturer's instructions. Mark the drilling location, set the hammer mode appropriate for concrete, and apply steady pressure while allowing the tool's percussion action to do the work. Withdraw periodically to clear dust if drilling deep holes, and use appropriate cutting speed and feed to avoid excessive wear on the carbide tip.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling concrete. For best results, start with a pilot position and use a depth stop if a controlled hole depth is required. Replace the bit if the carbide tip becomes worn or the bit produces irregular holes.
