Drill bit MEGA SDS+ 4 mm for concrete, model 80411

MEGA SDS+ 4 mm drill bit model 80411 is a carbide-tipped masonry drill designed for drilling small-diameter holes in concrete, brick and other masonry materials. The 4 mm diameter and SDS+ shank make it compatible with SDS+ rotary hammers and hammer drills, offering focused drilling for anchor holes, conduit entries and light chipping tasks. The cutting head geometry and flute design support efficient dust and chip evacuation to maintain drilling speed in compact-diameter applications.

Advantages

The carbide tip provides wear resistance and retains cutting performance when drilling into abrasive concrete and masonry. The SDS+ shank ensures fast, secure tool changes and reliable torque transfer. A narrow 4 mm diameter allows precise, minimally invasive holes for anchors and small fixtures, while the flute geometry promotes consistent chip removal to reduce binding and overheating during repeated use.

Suitable for

• Drilling anchor holes for small anchors and screws in concrete and brick
• Making conduit or cable entry points in masonry
• Light demolition and exploratory drilling where a small-diameter bit is needed
• Professional and DIY projects requiring compact, precise holes

Key specifications

• Tip material: carbide-tipped cutting head for increased hardness
• Shank type: SDS+ compatible shank for rotary hammers and hammer drills
• Diameter: 4 mm suitable for small anchors and fittings
• Intended materials: concrete, brick and general masonry
• Flute design: optimized for chip evacuation and drilling stability

How to use

Secure the SDS+ drill bit into the rotary hammer or hammer drill according to the tool manufacturer's instructions until it locks in place. Position the drill perpendicular to the work surface, start at low speed to establish the hole, then apply steady pressure with the hammer action engaged for reinforced concrete or masonry. Periodically withdraw the bit to clear dust and chips for better penetration and to avoid overheating. For through-holes, proceed until the required depth is reached and then remove the bit while the tool is running slowly to clear remaining debris.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask. Select a rotary hammer or hammer drill with SDS+ compatibility and suitable power for the material. For prolonged drilling or hard aggregate, use intermittent drilling and clear debris often to extend bit life. Store the bit in a dry case to prevent damage to the carbide tip.
