Concrete drill bit Irwin SDS MAX 18 mm IW2022104

The Irwin SDS MAX 18 mm concrete drill bit is designed for percussion drilling in concrete and masonry with heavy-duty rotary hammers that accept SDS MAX shanks. Its 18 mm diameter provides a clean, consistent bore for anchor installation, through-holes and general masonry work. The SDS MAX connection ensures secure engagement with the tool and efficient power transfer for repetitive drilling tasks on construction sites.

Advantages

This drill bit combines a robust tip geometry with a reinforced shaft to resist breakage and wear during intensive use. The SDS MAX shank design minimises slippage and enables quick bit changes while maintaining stability under high impact loads. Its 18 mm size is a commonly required diameter for anchors and fixings, offering a balance between hole size and drilling speed.

Suitable for

• Drilling anchor holes in concrete and blockwork
• Creating clearance holes for fixings and dowels
• General construction and renovation drilling tasks

Key specifications

• Diameter: 18 mm
• Shank type: SDS MAX
• Intended material: concrete, masonry
• Application: percussion drilling with rotary hammer

How to use

Fit the bit into an SDS MAX-compatible rotary hammer until it locks. Mark the drilling position and secure the work area to prevent movement. Start drilling at low speed to establish the hole, then apply steady pressure and use the hammer function for effective penetration. Periodically withdraw the bit to clear debris and prevent binding. Allow the bit to cool between long continuous runs to maintain performance.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask. Select drill speed and pressure suitable for the base material and avoid excessive side load on the bit. Replace the bit if tip wear or shaft deformation is observed to ensure safe and accurate drilling.

Irwin SDS MAX 18 mm concrete drill bit is compatible with standard SDS MAX rotary hammers commonly used in professional construction environments and renovation projects, providing predictable hole size and reliable engagement for anchors and fixings.
