Drill bit Irwin SDS+ 8 mm, for concrete, model IW2039412

Irwin SDS+ 8 mm drill bit (model IW2039412) is a concrete drill designed for use with SDS+ rotary hammers. The 8 mm diameter carbide-tipped bit is intended for creating clean, accurate holes in masonry and reinforced concrete, suitable for anchors, dowels and fasteners. Compatibility with SDS+ chucks ensures stable seating and efficient hammering action for both professional and DIY drilling tasks.

Advantages

The SDS+ 8 mm drill bit delivers precise hole dimensions and reduced wandering thanks to a carbide tip and flute design optimized for concrete. Its construction provides good resistance to wear during repeated drilling in masonry, while the standard SDS+ shank allows quick installation and secure locking in compatible rotary hammers. The bit’s diameter and geometry are balanced for controlled drilling speed and efficient dust removal.

Suitable for

• Drilling holes in concrete for anchor bolts and wall plugs
• Creating mounting points in masonry and brick
• Light to medium-duty demolition and installation tasks requiring SDS+ rotary hammers
• Professional tradespeople and DIY users needing reliable concrete drilling with an 8 mm hole

Key specifications

• Drill type: SDS+ carbide-tipped masonry bit
• Diameter: 8 mm
• Intended material: concrete, reinforced concrete, masonry
• Shank: SDS+ standard for rotary hammer compatibility
• Tip material: tungsten carbide for wear resistance
• Application: through-holes and anchor/drill points in masonry

How to use

Fit the SDS+ shank into the rotary hammer’s chuck until it locks securely. Select a suitable drilling speed and hammer setting on the tool according to the manufacturer’s guidance for concrete. Mark the drilling point, start drilling with light pressure to establish the hole, then apply steady force while allowing the hammer action to do the work. Withdraw the bit periodically to clear dust from the hole and prevent overheating; use a vacuum or compressed air to remove debris for clean anchor installation.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask when drilling concrete. For longer or deeper holes, start with smaller pilot holes only if required and use incremental depths to reduce stress on the bit. Store the bit dry and avoid excessive side loads to prolong tip life.
