Drill Bit Smart SDS+ 18 mm for Concrete, model 17-18300

Carbide-tipped Smart SDS+ drill bit 18 mm (model 17-18300) is designed for drilling concrete, masonry and natural stone with SDS+ rotary hammer drills. The 18 mm cutting diameter and carbide tip provide efficient material removal and extended wear resistance during hammer drilling. The SDS+ shank ensures secure engagement in compatible rotary hammers for stable, accurate drilling when installing anchors, dowels or creating through-holes in construction and renovation projects.

Advantages

The carbide tip improves durability and maintains cutting performance in abrasive materials. The 18 mm diameter suits common anchor and dowel sizes used in structural and finishing work. The SDS+ shank design enables quick insertion and reliable retention in SDS+ chucks, reducing slippage and enhancing transfer of hammer impact energy to the cutting edge. The bit’s geometry is balanced for straight drilling and efficient debris removal under hammer action.

Suitable for

• Drilling holes for anchors and expansion bolts in concrete and blockwork
• Preparing through-holes for pipes or conduits in masonry
• Installing dowels and fixing systems in renovation and construction
• Drilling into natural stone and hard masonry with SDS+ rotary hammers

Key specifications

• Cutting diameter: 18 mm
• Tip material: carbide
• Shank type: SDS+
• Intended materials: concrete, masonry, natural stone
• Typical application: hammer drilling with rotary hammer

How to use

Fit the SDS+ shank securely into the chuck of a compatible rotary hammer before operation. Select hammer-drilling mode and apply steady axial pressure while allowing the tool’s percussive action to advance the bit. Start at low speed to establish the pilot and increase force as appropriate, withdrawing periodically to clear debris and avoid excessive heat buildup. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling.

Usage recommendations

For optimal performance and service life, use this 18 mm carbide-tipped SDS+ bit with rotary hammers rated for hammer drilling in concrete. Avoid side loads and bending; let the tool’s percussive action perform cutting. Clear drilled material regularly and replace the bit if the tip shows significant wear or chipping.
