Core drill bit MEGA SDS+ 20 mm for concrete model 82040

MEGA SDS+ 20 mm drill bit for concrete model 82040 is a rotary SDS+ shank core drill designed to create precise 20 mm holes in concrete and masonry. Engineered for use with SDS+ rotary hammers, the bit provides secure retention in the chuck and efficient dust and debris removal while drilling. Intended for standard anchor, dowel and through-hole applications on construction and installation sites, this drill bit balances cutting performance and durability for repeated use in hardened materials.

Advantages

The MEGA SDS+ 20 mm drill bit features an SDS+ shank for fast, secure mounting and reduced play during rotary hammer operation. Its cutting geometry and flute design promote consistent material evacuation, reducing clogging and enabling steady drilling speed in concrete and masonry. Manufactured to withstand impact loads typical for rotary hammers, the bit offers reliable service life when used with appropriate drilling technique and recommended tools.

Suitable for

• Drilling 20 mm anchor and dowel holes in concrete
• Creating through-holes in brick and blockwork
• Preparing mounting points for fixtures, electrical boxes and plumbing
• General construction and renovation tasks requiring 20 mm holes

Key specifications

• Drill diameter: 20 mm
• Shank type: SDS+ rotary hammer shank
• Intended material: concrete and masonry
• Application: anchor, dowel and through-holes
• Design: core drill geometry with flutes for debris removal

How to use

Install the MEGA SDS+ 20 mm drill bit into a compatible SDS+ rotary hammer according to the tool manufacturer's instructions. Position the bit at the marked drilling point, keep the tool steady and apply moderate axial pressure; allow the hammer action to do the cutting rather than forcing the bit. Periodically retract the bit to clear dust and debris from the hole and flutes, especially when drilling deep holes. Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask or extraction when working in dusty conditions.

Usage recommendations

For best results, use the bit with SDS+ rotary hammers rated for percussion drilling in concrete. Maintain a consistent feed rate, avoid excessive lateral force, and replace the bit if cutting performance noticeably declines or if the tip becomes damaged.
