Drill Bit GRAPHITE SDS‑MAX 18 mm for Concrete, model 57H514

GRAPHITE SDS‑MAX 18 mm drill bit (model 57H514) is designed for rotary hammers with SDS‑MAX chucks to perform drilling in reinforced and non‑reinforced concrete, masonry and natural stone. The 18 mm diameter provides a balance between bore size and structural integrity, enabling efficient hole making for anchors, through‑holes and insert installations on construction and renovation sites. The shank compatibility with SDS‑MAX systems ensures secure engagement and effective transfer of impact energy for heavy‑duty drilling and chiseling tasks.

Advantages

The GRAPHITE SDS‑MAX 18 mm drill bit offers reliable bit retention and efficient impact energy transfer thanks to its SDS‑MAX shank design. Its geometry is optimised for penetration into hard substrates such as concrete and stone while reducing bit wander and improving straightness of the drilled hole. The tool is suitable for repeated use in demanding conditions and pairs with standard SDS‑MAX rotary hammers used in professional and DIY applications.

Suitable for

• Drilling anchor holes in reinforced concrete and masonry
• Creating through‑holes for utilities and installations
• Chiseling and demolition tasks that require SDS‑MAX compatibility
• Renovation and construction site drilling where 18 mm bore is required

Key specifications

• Diameter: 18 mm
• Shank type: SDS‑MAX compatible
• Primary materials: concrete, reinforced concrete, masonry, natural stone
• Intended use: rotary hammer drilling and heavy‑duty chiseling
• Typical applications: anchor holes, through‑holes, utility penetrations

How to use

Select a rotary hammer with an SDS‑MAX chuck and secure the bit by inserting the shank until it locks. Mark the drilling position and start at low speed to establish the pilot groove, then apply steady pressure and engage the hammer function for efficient penetration into concrete or masonry. Use controlled feed pressure and avoid excessive lateral forces to maintain hole straightness and extend bit life. Withdraw the bit periodically to clear dust from the hole when drilling deep or long holes.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask or extraction when drilling. For reinforced concrete, consider using a center punch or pilot marking to prevent slippage. Match bit diameter to anchor or insert specifications and replace the bit when wear degrades cutting performance or straightness.
