Drill Bit MEGA SDS+ 8 mm for Concrete, Model 80840

MEGA SDS+ 8 mm drill bit (model 80840) is designed for drilling clean, single-diameter 8 mm holes in concrete and masonry. Compatible with SDS+ chucks, this bit is intended for use with rotary-hammer and hammer-drill tools to create anchor and dowel holes or through-holes in building materials. The geometry and shank design provide secure fitting in SDS+ tool holders and steady drilling performance in common construction and renovation tasks.

Advantages

This 8 mm concrete bit delivers consistent bore diameter and reliable percussion performance when used in appropriate SDS+ rotary-hammer or hammer-drill tools. Its standard diameter is suitable for common anchors and dowels, allowing fast, repeatable hole production for installation work. The SDS+ shank ensures quick tool changes and a stable connection under hammering action, while the bit length and flute design clear dust to maintain drilling speed.

Suitable for

• Drilling 8 mm anchor and dowel holes in concrete and masonry
• Through-holes for installations and fixtures
• Construction, renovation, and light installation work requiring a standard-diameter concrete bit

Key specifications

• Diameter: 8 mm
• Shank type: SDS+
• Intended materials: concrete and masonry
• Compatible drilling modes: rotary and hammer (percussion) drilling
• Typical applications: anchor, dowel, and through-hole drilling

How to use

Fit the SDS+ shank securely into the tool chuck and select the appropriate drilling mode (hammer function for concrete). Position the bit perpendicular to the work surface, apply steady pressure, and start drilling at low speed until the bit establishes a guide. Increase pressure and maintain control while allowing the tool to provide the percussive action. Withdraw the bit periodically to clear dust if drilling deep holes. After drilling, clean the hole before inserting anchors or dowels.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection, and dust mask. Match the bit diameter to the anchor or dowel specifications, and ensure the SDS+ tool is rated for hammer drilling in concrete. For longer life and consistent results, avoid excessive lateral force and use periodic retraction to remove debris.
