Drill Bit Smart SDS Plus Duo 14 x 1400/1350 mm

Smart SDS Plus Duo drill bit 14 x 1400/1350 mm is a long-reach rotary hammer bit designed for deep drilling in concrete and masonry. The bit features an SDS Plus shank for compatibility with SDS Plus rotary hammers and a 1350 mm working length that enables drilling through thick walls, slabs, and structural elements where standard bits are too short. The 14 mm diameter provides a balance between hole size and structural integrity for anchor, conduit, and pipe installations.

Advantages

The drill bit is engineered for extended-reach applications and maintains stability in the chuck thanks to its SDS Plus connection. Its long working length reduces the need for extensions or secondary drilling steps and helps achieve consistent hole depth in deep drilling tasks. The 14 mm diameter is commonly used for medium-sized anchors and through-holes, while the overall construction is optimized for use in concrete and masonry materials.

Suitable for

• Drilling deep holes for anchors and through-conduit installations in concrete
• Creating passages for pipes and electrical conduits through thick walls and slabs
• Professional and renovation work requiring extended reach without extensions

Key specifications

• Shank type: SDS Plus compatible
• Diameter: 14 mm
• Overall length: 1400 mm
• Working length: 1350 mm
• Intended materials: concrete, masonry

How to use

Use the bit in an SDS Plus rotary hammer set to the appropriate hammer-drill mode for concrete or masonry. Secure the bit in the tool's chuck until it locks, mark the required drilling depth on the bit or the workpiece, and position the drill perpendicular to the surface. Start drilling at low speed to create a pilot groove, then apply steady pressure while allowing the hammer action to do the cutting. Withdraw the bit periodically to clear dust and debris from the hole and to prevent overheating.

Usage recommendations

Wear appropriate personal protective equipment, including eye and ear protection, and use a dust extraction system or a vacuum to reduce silica dust exposure when drilling into concrete. For accurate anchor installation, verify hole diameter and depth against anchor manufacturer instructions. Store the bit in a protective case or rack to avoid damage to the tip and shank.
