Drill Bit Smart SDS+ 12 mm (model 17-12450) for concrete

Smart SDS+ 12 mm concrete drill bit (model 17-12450) is a rotary hammer accessory designed for drilling into concrete and masonry. It features an SDS+ shank for fast and secure engagement with compatible rotary hammers and a 12 mm working diameter suitable for medium-sized anchor holes, through-holes for conduits, and general fixing tasks in construction and renovation. The bit is intended for rotary hammer drilling where percussion action is required to penetrate dense materials such as concrete, brick and block.

Advantages

The SDS+ shank ensures quick tool changes and reliable retention under impact load, while the 12 mm diameter provides a balance between drilling speed and structural suitability for typical anchor and conduit installations. The carbide tip design enhances cutting performance and wear resistance during repetitive drilling in abrasive materials. Compatibility with SDS+ rotary hammers allows use with a broad range of professional and consumer-class tools.

Suitable for

• Drilling anchor holes in concrete for bolts and expansion anchors
• Creating through-holes for electrical conduits and plumbing pipes
• Installing fixtures, brackets and mounting plates in masonry
• General-purpose rotary hammer drilling in brick, block and reinforced concrete (where hole diameter is appropriate)

Key specifications

• Working diameter: 12 mm
• Shank type: SDS+
• Intended material: concrete and masonry
• Tip material: carbide cutting tip for enhanced wear resistance
• Typical application: rotary hammer drilling with percussion

How to use

Install the drill bit into an SDS+ compatible rotary hammer until it locks into the chuck. Select the hammer-drilling mode on the tool and position the bit at the intended drilling point. Apply steady forward pressure and allow the tool's percussion action to perform the cutting; avoid excessive force that could overload the tool or the bit. Withdraw the bit periodically to clear dust from the hole, especially when drilling deep openings. After use, clean the bit and store it dry to minimise corrosion.

Usage recommendations

Use appropriate personal protective equipment: safety goggles, hearing protection and dust mask. Match drill diameter to anchor or conduit size and ensure the rotary hammer is set to SDS+ mode. For reinforced concrete, use steady technique and consider pilot holes or intermittent withdrawal to clear rebar debris. Replace the bit when cutting performance declines significantly.
