GRAPHITE SDS+ masonry drill bit 16 mm (model 57H474) for concrete

GRAPHITE SDS+ masonry drill bit 16 mm is designed for efficient drilling into concrete, masonry and natural stone using SDS+ rotary hammer tools. The 16 mm diameter tip and flute geometry enable rapid chip removal and stable centering for through-holes and anchor holes. The bit is intended for professional and DIY applications where reliable concrete drilling is required, such as installation of anchors, conduits, and fixtures.

Advantages

The SDS+ shank ensures secure retention and quick bit changes in compatible rotary hammers. Optimised flute design promotes effective dust and debris evacuation, reducing clogging and heat build-up during continuous drilling. Hardened cutting tip maintains shape and cutting performance over repeated use, while the 16 mm diameter provides a balance between hole clearance and drill speed for common anchoring tasks.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Creating passage holes for conduits and pipes in walls
• Preparing mounting points for fixtures and brackets
• General construction and renovation tasks requiring concrete drilling

Key specifications

• Tip diameter: 16 mm
• Shank type: SDS+
• Material compatibility: concrete, masonry, natural stone
• Application: rotary hammer drilling for through-holes and anchor holes
• Design features: optimised flute for chip removal; hardened cutting tip for durability

How to use

Select a compatible SDS+ rotary hammer and secure the drill bit in the chuck according to the tool manufacturer’s instructions. Mark the drilling point and, if necessary, use a center punch to prevent walking. Begin drilling at low speed to seat the bit, then apply steady pressure and operate at the hammering speed appropriate for the material. Withdraw the bit periodically to clear debris and reduce heat build-up, and keep the drill aligned to maintain hole straightness.

Usage recommendations

Use the drill bit with appropriate personal protective equipment (safety glasses, gloves, hearing protection). For reinforced concrete, check for rebar with a detector before drilling. Replace the bit when cutting performance or centring deteriorates to maintain hole quality.
