Drill bit Irwin Speedhammer Plus 18.0 mm x 600 mm, model 10502030, concrete/Aggregate use

The Irwin Speedhammer Plus 18.0 mm x 600 mm is a long SDS-compatible masonry drill bit designed for drilling through concrete and aggregate materials. Intended for use with rotary hammer drills, this 600 mm length provides extended reach for creating through-holes, anchor points and service openings in structural and installation work. The bit's diameter and length make it suitable for drilling deep holes for anchors, sleeves and cable or conduit runs where a reliable, straight hole is required.

Advantages

The Speedhammer Plus geometry and carbide tip construction deliver controlled cutting and effective dust removal during rotary hammer drilling. The extended 600 mm length enables access to recessed or hard-to-reach areas without the need for extensions or couplers. Designed for masonry and concrete, the bit maintains straightness and stability when used with compatible SDS chucks, helping to reduce walking and wear on the tool and fasteners.

Suitable for

• Drilling through concrete for anchor installation and through-bolts
• Creating service channels and conduit/cable passages in masonry
• Structural installation work where long-reach holes are required
• Preparing holes for sleeve anchors, chemical anchors and heavy-duty fixings

Key specifications

• Diameter: 18.0 mm
• Overall length: 600 mm
• Shank type: SDS-compatible (rotary hammer use)
• Application material: Concrete and aggregate masonry
• Tip: Carbide-tipped for masonry cutting performance

How to use

Install the drill bit into a compatible rotary hammer drill with an SDS-style chuck, ensuring it is fully seated and locked. Select the rotary or hammer mode as required by the material and start drilling at low speed to establish the hole, then apply steady pressure while allowing the hammer action to perform the cutting. Withdraw the bit periodically to clear dust from deep holes and to prevent excessive heat build-up. Use appropriate personal protective equipment, such as eye protection, hearing protection and a dust mask or extraction when drilling.

Usage recommendations

For best results, use the Speedhammer Plus bit with a rotary hammer rated for the job size and follow manufacturer guidance on drill speed and impact settings. In reinforced concrete, take care to identify and avoid rebar where required; if encountering reinforcement, reduce feed pressure and use intermittent drilling to prevent tip damage. Clean and store the bit dry after use to maintain cutting performance.
