Drill Bit GRAPHITE 57H490 SDS+ 20 mm

GRAPHITE SDS+ drill bit 20 mm (model 57H490) is designed for use with SDS+ rotary hammer systems for drilling into concrete, masonry and natural stone. The bit features an SDS+ shank for secure, quick insertion and removal, and a robust construction intended to withstand impact drilling in construction and renovation tasks.

Advantages

This 20 mm SDS+ drill bit offers reliable drilling performance in hard substrates thanks to a hardened tip and sturdy flute geometry that evacuates debris efficiently. The standardized SDS+ shank ensures compatibility with a wide range of rotary hammers and provides a stable connection that reduces wobble during drilling. The solid build supports repetitive use on construction sites and during installation work.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Making passage holes in masonry and brick
• Creating fixing points in natural stone
• Use with SDS+ rotary hammers on construction and renovation projects

Key specifications

• Diameter: 20 mm
• Shank type: SDS+
• Intended materials: concrete, masonry, natural stone
• Application: rotary hammer drilling with impact
• Construction: hardened tip with spiral flute for chip removal

How to use

Select the SDS+ rotary hammer mode with hammering action enabled. Insert the drill bit into the tool’s chuck until it locks with the SDS+ connection. Position the bit perpendicular to the work surface and start drilling at low speed to establish the hole, then increase speed and apply steady pressure without forcing the bit. Periodically withdraw the bit to clear dust and debris for more efficient drilling and reduced wear. Use appropriate anchor sizes for the drilled diameter.

Usage recommendations

For best results, use the drill bit with a rotary hammer that supports SDS+ shanks and matches the required impact energy for concrete work. Wear eye and ear protection and a dust mask when drilling in concrete or masonry. If drilling deep holes, clear debris frequently and allow the bit to cool to prolong service life.
