Drill bit for concrete MEGA SDS+ 28 mm model 82840

MEGA SDS+ 28 mm model 82840 is a drill bit designed for efficient drilling in concrete and masonry with SDS+ rotary hammer drills. The 28 mm diameter is intended for anchor holes and through-holes in both reinforced and non-reinforced concrete. The SDS+ shank provides a secure connection with compatible rotary hammers and enables quick bit changes during construction, installation, and repair tasks.

Advantages

The MEGA SDS+ 28 mm drill bit combines a robust carbide tip and reinforced flute geometry to ensure reliable chip evacuation and prolonged service life when used in masonry materials. Its SDS+ shank design reduces play in the chuck for accurate drilling and fast replacement, while the 28 mm diameter meets common requirements for anchor and fixing installations. The bit is manufactured to withstand repeated impacts from rotary hammer action, maintaining cutting efficiency over multiple uses.

Suitable for

• Drilling anchor holes for mechanical fixings in concrete
• Creating through-holes in non-reinforced concrete and masonry
• Installation work for HVAC, electrical conduit and plumbing
• Renovation and repair tasks requiring standard-diameter concrete holes

Key specifications

• Diameter: 28 mm
• Shank type: SDS+
• Intended material: concrete and general masonry
• Primary use: anchor holes and through-holes
• Compatibility: SDS+ rotary hammer drills

How to use

Secure the MEGA SDS+ 28 mm drill bit into the SDS+ chuck of a compatible rotary hammer until it locks. Select the hammer drilling mode on the tool and position the bit at the marked drilling point. Apply steady axial pressure, allowing the tool's impact action to do the cutting; avoid excessive lateral forces. For deeper holes, periodically withdraw the bit to remove dust and debris and improve cooling. After drilling, clean the hole of dust before inserting anchors or fixings.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete. Match drill speed and feed pressure to the drill and material; use lubricant or water only if recommended for the specific tool and bit combination. Inspect the bit for wear or damage before use and replace when cutting performance diminishes.
