Drill Bit GRAPHITE SDS+ 12 mm for concrete, model 57H438

GRAPHITE SDS+ 12 mm drill bit model 57H438 is a masonry drill designed for drilling holes in concrete, brick and similar hard building materials. The bit features an SDS+ shank for secure fitting in SDS+ rotary hammer chucks and a 12 mm working diameter suitable for anchor installation and through-holes for pipes or electrical conduits. The product is intended for professional and DIY use where reliable concrete drilling is required.

Advantages

The SDS+ shank ensures fast and stable bit changes and firm retention in compatible rotary hammers. The 12 mm diameter provides a balance between hole size and drilling speed for common fixing and installation tasks. The bit is engineered for concrete and masonry applications to maintain cutting efficiency and proper dust evacuation during hammer drilling.

Suitable for

• Drilling anchor and fixing holes in concrete and brick
• Creating pass-through holes for electrical conduits and plumbing
• General masonry drilling in construction and renovation
• Use with SDS+ rotary hammers for hammer drilling tasks

Key specifications

• Diameter: 12 mm
• Shank type: SDS+
• Intended material: concrete, brick and similar masonry
• Application: hammer drilling for anchors, conduit and fixture installation

How to use

Install the drill bit into an SDS+ compatible rotary hammer chuck until it locks. Select an appropriate hammer drilling mode on the rotary hammer and position the bit perpendicular to the work surface. Apply steady pressure without forcing the tool; allow the hammer action to perform most of the work. Withdraw the bit periodically to clear dust from the hole if drilling deep openings, and use suitable personal protective equipment such as eye protection, hearing protection and a dust mask.

Usage recommendations

For longer tool life and more efficient drilling, start with a lower feed pressure to establish the pilot hole, maintain moderate cooling pauses when drilling deep holes, and clear debris regularly. Use appropriate anchor or fixing products sized to the 12 mm hole and select a rotary hammer with power and impact energy suited to concrete work.
