## Summary description

GRAPHITE SDS‑MAX drill bit, 20 mm diameter, designed for use with SDS‑MAX rotary hammers for drilling in concrete. The bit suits heavy‑duty masonry and reinforced concrete applications, providing percussion drilling capability and compatibility with SDS‑MAX chucks. Intended for professional and DIY tasks requiring reliable concrete penetration.

## Long description

GRAPHITE SDS MAX 20mm concrete drill bit is designed for rotary hammer drilling in reinforced and non-reinforced concrete, masonry and stone. The 20 mm diameter provides a balance between drilling speed and hole size for anchor installation, through-holes and utility passages. The SDS MAX shank ensures secure engagement with compatible rotary hammers, enabling efficient power transfer and stable drilling performance.
Advantages
This drill bit combines a carbide-tipped cutting head with a robust body to resist wear during repeated use in abrasive materials. The SDS MAX connection offers fast, tool-free bit changes and reliable retention under heavy impact loads. Its 20 mm diameter delivers consistent hole dimensions for anchoring and dowelling while maintaining acceptable drilling speed and control.
Suitable for
 Drilling holes for anchors and chemical studs in concrete
 Creating through-holes for pipes and wiring in masonry
 Preparing fixing points for structural or installation work
Key specifications
 Diameter: 20 mm
 Shank type: SDS MAX
 Intended materials: reinforced concrete, non-reinforced concrete, masonry, natural stone
 Tip material: carbide-tipped cutting head
 Application mode: rotary hammer drilling with hammer function
How to use
Install the bit into an SDS MAX compatible rotary hammer until it locks in place. Use the hammer drilling mode and apply steady axial pressure, allowing the tool to perform the impact action rather than forcing the bit. Start at low speed to position the hole, then continue at a suitable drilling speed for the material. Periodically withdraw the bit to clear dust from the hole and reduce friction. For deep holes, clear debris frequently to maintain drilling efficiency.
Usage recommendations
Wear appropriate personal protective equipment including eye protection, hearing protection and a dust mask. Use a drill with sufficient power and correct SDS MAX chuck. For precise anchor holes, verify diameter and depth requirements before drilling and use water or dust extraction when required to reduce airborne silica dust.
