Drill bit Smart SDS+ 18 mm for concrete, model 17-18450

The Smart SDS+ 18 mm drill bit for concrete, model 17-18450, is engineered for drilling clean, accurate holes in concrete and masonry. Designed for use with SDS+ rotary hammer drills, this 18 mm diameter bit is intended for through-holes and anchor fixing where firm retention and efficient percussion transfer are required. The reinforced shank improves tool engagement and reduces slippage in the drill chuck, while the carbide tip geometry provides effective material removal in reinforced and unreinforced concrete.

Advantages

This SDS+ drill bit offers reliable percussion energy transfer from the rotary hammer to the cutting edge, resulting in consistent drilling progress in hard substrates. The reinforced shank design enhances retention and reduces wobble during operation, contributing to more accurate hole placement. The carbide tip maintains cutting performance and extends service life under typical construction site conditions, and the bit’s compatibility with standard SDS+ holders ensures straightforward tool pairing.

Suitable for

• Drilling through-holes for anchors and bolts in concrete and masonry
• Creating holes for electrical conduits, plumbing sleeves, and fastening systems
• Renovation and construction work requiring repeatable, accurate concrete drilling

Key specifications

• Diameter: 18 mm
• Shank type: SDS+ compatible reinforced shank
• Intended materials: concrete and masonry
• Primary applications: through-holes and anchor fixing
• Tip material: carbide cutting tip for improved durability

How to use

Secure the Smart SDS+ 18 mm drill bit into the SDS+ chuck of a rotary hammer drill according to the drill manufacturer’s instructions. Mark the drilling location and, when appropriate, start at low speed to establish a pilot indent before applying full hammer function. Use steady axial pressure without forcing the bit; allow the percussion action to do the work. For deeper holes, periodically withdraw the bit to clear dust and debris and to prevent overheating. Wear suitable personal protective equipment, including eye and hearing protection, and follow safety guidelines for drilling into concrete.

Usage recommendations

For best results, use with a rotary hammer that supports SDS+ bits and select an appropriate drilling mode for concrete. When drilling reinforced concrete, apply controlled pressure and withdraw the bit regularly to remove debris. Replace the bit when cutting performance declines or when the carbide tip shows visible wear to maintain hole accuracy and reduce load on the tool.
