Concrete drill bit Irwin Speedhammer Plus 8.0 mm × 600 mm, long SDS‑plus for hammer drills

Irwin Speedhammer Plus long concrete drill bit, 8.0 mm diameter and 600 mm length, is engineered for SDS‑plus hammer drills to perform drilling in concrete, masonry and reinforced concrete. The extended length enables through and deep drilling where standard bits are too short. The Speedhammer Plus geometry is designed to improve chiseling action and accelerate removal of cuttings, delivering steady penetration when working with hardened substrates.

Advantages

This SDS‑plus drill bit combines a reinforced shank with a purpose‑designed tip profile to increase durability and reduce wear during repeated hammer drilling. Its optimized flute geometry promotes faster debris evacuation to help maintain drilling speed and reduce clogging. The long 600 mm length allows reach into deep holes and installation cavities while maintaining concentricity for cleaner holes.

Suitable for

• Through drilling in concrete walls and floors
• Deep anchor and fixing holes for installation work
• Drilling in reinforced concrete and masonry
• Construction, renovation and electrical/plumbing installation tasks

Key specifications

• Diameter: 8.0 mm
• Total length: 600 mm
• Shank type: SDS‑plus compatible
• Tip geometry: Speedhammer Plus chiseling profile for efficient material removal
• Application materials: concrete, reinforced concrete, masonry

How to use

Install the drill bit into an SDS‑plus hammer drill according to the tool manufacturer's instructions, ensuring it locks securely. Use the hammer drilling function for concrete and masonry; apply steady axial pressure without forcing the bit. Start at low speed to position the bit, then increase speed as the hole stabilizes. Periodically withdraw the bit to clear debris from deep holes and to avoid overheating.

Usage recommendations

Wear appropriate personal protective equipment including eye and hearing protection and a dust mask when drilling. For anchor and fixing holes, verify required hole depth and clean the hole of dust before inserting fixings. Use lubrication or reduced impact only if recommended by the drill manufacturer; otherwise operate in standard hammer mode for optimal performance.
