Drill Bit MEGA SDS+ 14 mm for Concrete, model 81445

MEGA SDS+ 14 mm drill bit for concrete, model 81445, is a rotary-hammer bit designed for drilling into concrete, reinforced concrete and masonry. The bit features an SDS-plus shank for secure fitting in compatible rotary hammers and a 14 mm cutting diameter suited for anchor holes, through-holes for pipe and conduit fixings, and general fastening tasks on construction and renovation sites.

Advantages

The SDS+ shank provides quick and secure insertion into SDS-plus chucks, reducing slippage and improving energy transfer from the hammer. The 14 mm diameter offers a balance between hole size and drilling speed for common anchoring and fixing work. The flute geometry and carbide tip are engineered to evacuate dust efficiently and maintain cutting performance when drilling into dense concrete and masonry.

Suitable for

• Drilling anchor and fastening holes in concrete and blockwork
• Creating pass-through holes for conduits, pipes and cables
• Preparation work for installation of brackets, rails and fixtures
• General renovation and construction drilling tasks on masonry substrates

Key specifications

• Drill type: SDS-plus rotary hammer bit
• Cutting diameter: 14 mm
• Intended material: concrete, reinforced concrete, masonry
• Shank type: SDS-plus
• Tip material: carbide cutting tip
• Flute design: spiral flute for dust removal

How to use

Install the bit into an SDS-plus rotary hammer until it locks in place according to the tool manufacturer's instructions. Select the hammer-drilling mode and apply steady axial pressure while allowing the tool to do the work; avoid excessive lateral force. Use progressive drilling when penetrating reinforced areas, retracting periodically to clear dust. After drilling, withdraw the bit and clear remaining debris from the hole before inserting anchors or fixings.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match drill speed and hammer energy to the substrate hardness; for prolonged drilling or hard concrete, consider intermittent operation to reduce heat build-up. Ensure the rotary hammer is compatible with SDS-plus accessories and select anchor types suited to a 14 mm hole.
