Drill Bit MEGA SDS+ 28 mm model 82860

MEGA SDS+ 28 mm model 82860 is a rotary and hammer drill bit designed for drilling 28 mm diameter holes in concrete, masonry and natural stone. The bit uses an SDS+ shank to ensure quick insertion and secure retention in compatible rotary hammers, enabling efficient transfer of impact energy for through-holes, anchor installation and medium-duty demolition or retrofit tasks that require precise 28 mm holes.

Advantages

The SDS+ connection provides fast, tool-free engagement and stable retention during heavy rotation and hammering. The 28 mm working diameter balances material removal with hole accuracy for anchors and sleeves. The bit's geometry and carbide tip are optimized for sustained drilling in hard substrates, reducing the need for frequent bit changes and maintaining cutting performance during extended use.

Suitable for

• Drilling through-holes in concrete and masonry for anchor installation
• Preparing holes for chemical or mechanical anchors and sleeves
• Medium-duty demolition or retrofit tasks requiring 28 mm holes
• Drilling in natural stone and dense brick where a 28 mm bore is required

Key specifications

• Nominal diameter: 28 mm
• Shank type: SDS+ compatible
• Intended substrates: concrete, masonry, natural stone
• Application modes: rotary and hammer drilling
• Typical uses: through-holes, anchor and sleeve preparation, medium-duty demolition

How to use

Fit the MEGA SDS+ 28 mm bit into a compatible rotary hammer with an SDS+ chuck until it locks securely. Select the hammer or hammer-plus-rotation mode depending on the substrate; use hammer-plus-rotation for concrete and dense masonry. Start drilling at low speed to establish the bore, then apply steady pressure and moderate feed rate while allowing the tool's percussion to break the material. Withdraw periodically to clear dust and debris from the hole, and use compressed air or a brush to remove remaining dust before inserting anchors or sleeves.

Usage recommendations

Use appropriate personal protective equipment including eye, ear and respiratory protection when drilling. Match the drill bit diameter to anchor or sleeve specifications and ensure the rotary hammer is rated for SDS+ bits and the required impact energy. For prolonged drilling or large-diameter holes, consider using water cooling only if the tool and bit are specified for wet use; otherwise, rely on intermittent drilling and dust extraction to prevent overheating and preserve tip life.
