Drill bit Art-Pol AR48470 SDS+ 20 mm for concrete

Art-Pol AR48470 SDS+ 20 mm for concrete is a rotary hammer drill bit designed for use with SDS+ chucks. With a 20 mm diameter and a carbide tip, this drill bit is intended for drilling holes in concrete, masonry and similar mineral materials. The flute geometry promotes efficient dust removal during drilling, helping maintain drilling speed and reduce clogging when making holes for anchors, dowels and installation fixtures.

Advantages

The carbide tip provides increased wear resistance and a longer service life when working with abrasive concrete and masonry. The SDS+ shank ensures quick, secure tool engagement and easy bit changes without additional adapters. Flute design supports efficient evacuation of dust and debris, which helps to maintain drilling efficiency and reduces heat buildup at the cutting edge. The 20 mm diameter is suitable for common anchor and fastening sizes used in building and installation work.

Suitable for

• Drilling anchor and dowel holes in concrete and reinforced concrete
• Preparing openings for installation fixtures and mechanical fasteners
• Drilling through masonry, brick and similar mineral substrates

Key specifications

• Shank type: SDS+
• Diameter: 20 mm
• Tip material: carbide (tungsten carbide)
• Intended materials: concrete, masonry, brick and similar mineral substrates
• Typical application: rotary hammer drilling with hammer and rotation modes

How to use

Install the drill bit into an SDS+ compatible rotary hammer until it locks in position. Select the hammer-drilling mode and use steady axial pressure; avoid excessive lateral force to prevent premature wear or breakage. Start drilling at low speed to establish the hole, then apply continuous pressure and allow the tool to do the work. Periodically withdraw the bit to clear accumulated dust and to prevent clogging of the flutes when drilling deep holes. For reinforced concrete, use controlled force and appropriate drill speed to limit stress on the carbide tip.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask and hearing protection). For best results in dust control and hole quality, combine with a dust extraction system or periodically remove dust from the hole. Match the 20 mm diameter to the recommended anchor or dowel size and use a compatible rotary hammer with SDS+ chuck rated for the required impact energy.
