SDS+ concrete drill bit Abraboro 14 mm AB00004028

The Abraboro SDS+ concrete drill bit 14 mm is designed for impact drilling in concrete, masonry and natural stone with rotary hammer drills that accept SDS+ shanks. The 14 mm diameter provides a standard hole size for common anchor bolts, dowels and cable or conduit passages. The shank geometry ensures secure coupling to SDS+ chucks and reliable transfer of percussive force for efficient material removal.

Advantages

This SDS+ concrete drill bit offers a balance of drilling speed and durability for general construction use. Its compatible shank design reduces slippage in the chuck under hammer action and helps maintain concentric rotation. The fluted cutting body evacuates dust and debris effectively during drilling, supporting steady progress and reducing heat buildup. The robust carbide tip maintains cutting performance when used in reinforced concrete and varied masonry materials.

Suitable for

• Drilling holes for anchors and expansion bolts in concrete and block
• Creating passages for electrical conduits and plumbing through masonry
• Installing fixtures, brackets and rails on stone or concrete surfaces
• General light to medium-duty construction and renovation tasks

Key specifications

• Diameter: 14 mm
• Shank type: SDS+
• Intended materials: concrete, masonry, natural stone
• Tip material: carbide cutting tip
• Application: impact drilling with rotary hammer drills

How to use

Secure the drill bit into an SDS+ compatible rotary hammer until it locks in place. Mark the drilling position and, where possible, start at low speed to establish the pilot location before engaging hammer mode. Apply steady axial pressure without forcing the tool; allow the drill and percussive action to remove material. Periodically withdraw the bit to clear debris from the hole and prevent clogging. For reinforced concrete, proceed with caution when encountering rebar and avoid excessive lateral force that could damage the bit.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and a dust mask when drilling. Use a drill with an SDS+ chuck and appropriate power rating for the material and hole diameter. For prolonged drilling or deep holes, use incremental drilling and regular bit withdrawal to extend tool life and maintain drilling efficiency.
