Drill bit Art-Pol SDS+ 20 mm AR48320 for concrete

Art-Pol SDS+ 20 mm AR48320 is a carbide-tipped drill bit designed for drilling concrete and masonry with SDS+ rotary hammer systems. The 20 mm diameter creates holes suitable for standard anchors and dowels, offering a balance between penetration speed and hole precision. It is made to fit SDS+ chucks and to withstand the impact and rotational forces typical of hammer drilling in construction and renovation projects.

Advantages

The drill bit features a reinforced shank and a tailored carbide tip geometry that improves cutting efficiency and extends tool life during repeated concrete drilling. Its SDS+ shank enables quick and secure bit changes without adapters, while the 20 mm size provides compatibility with a wide range of fixing accessories. The construction resists chipping and deformation under heavy-duty use and maintains a consistent hole diameter for reliable anchor seating.

Suitable for

• Drilling holes for anchors and dowels in concrete walls and floors
• Making feed-through openings for pipe and cable installations in masonry
• Pre-drilling for mechanical fastening during renovation and construction
• Tasks requiring repeated, consistent holes in reinforced concrete and brickwork

Key specifications

• Type: SDS+ hammer drill bit
• Material tip: tungsten carbide cutting tip
• Shank: SDS+ compatible shank for rotary hammers
• Diameter: 20 mm
• Intended material: concrete, masonry, brick, and reinforced concrete

How to use

Select an SDS+ rotary hammer that supports a 20 mm drill bit and secure the bit in the chuck until it locks. Mark the drilling point, ensure the work surface is stable, and start drilling at low speed to center the bit, then apply steady pressure and use the hammer function for efficient penetration. Periodically withdraw the bit to clear dust from the hole and avoid overheating. For reinforced concrete, locate rebar before drilling or use appropriate techniques to drill through reinforcement carefully.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection, and dust mask. For best results, match the drill speed and hammer setting to the material density, and replace the bit when cutting performance declines or when the carbide tip shows visible wear. Store the bit dry and protected to prevent corrosion of the shank.
