SDS+ masonry drill bit MEGA 8 mm (model 80811) for concrete and stone

MEGA SDS+ masonry drill bit, 8 mm diameter (model 80811) is intended for drilling precise holes in concrete, natural stone and masonry using SDS+ rotary or hammer drills. The bit combines an SDS+ compatible shank with a carbide cutting tip to maintain drilling accuracy and wear resistance when working in hard substrates. Its 8 mm diameter makes it suitable for anchors, dowels and small-diameter installations in construction and renovation tasks.

Advantages

The carbide tip provides durable cutting performance and improved penetration in concrete and stone compared with standard steel tips. The SDS+ shank ensures secure coupling with compatible hammer drills, reducing slippage and facilitating quick changeover. Optimized flute geometry assists in efficient dust removal and helps maintain consistent drilling speed and hole quality during repeated use.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Installing fixtures and fittings that require 8 mm holes
• Renovation and repair tasks involving stone or brick substrates
• Light to medium-duty construction and installation work with SDS+ tools

Key specifications

• Diameter: 8 mm
• Shank type: SDS+ compatible
• Tip material: carbide
• Intended materials: concrete, natural stone, brick and masonry
• Tool compatibility: SDS+ rotary and hammer drills

How to use

Insert the SDS+ shank into the drill's chuck until it locks according to the drill manufacturer's instructions. Select an appropriate drilling mode (rotary hammer for solid concrete, rotary-only for lighter masonry if required). Start at low speed to create a guide indentation, then increase speed and apply steady pressure without forcing the bit. Periodically withdraw the bit to clear dust from the hole and allow the bit to cool if drilling multiple holes consecutively.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and hearing protection. For reinforced concrete, consider using a dedicated rebar-detecting tool before drilling. To extend tool life, avoid overheating by allowing cooling pauses during continuous drilling and use appropriate percussion settings for the substrate.
