Drill Bit Irwin SDS Plus 8 x 160 mm — for concrete, model IW2039120

Irwin SDS Plus 8 x 160 mm drill bit is engineered for rotary hammer drills with an SDS Plus shank and designed specifically for drilling into concrete, masonry and natural stone. With an 8 mm diameter and 160 mm overall length, this model provides the reach and rigidity required for common construction and renovation tasks such as installing anchors, running conduits and fixing fixtures to solid substrates.

Advantages

The SDS Plus fitting ensures secure retention and fast bit changes in compatible hammer drills. Tungsten carbide tip geometry and a spiral flute profile deliver efficient dust removal and consistent penetration in hardened materials. The combination of shaft strength and optimized flute design reduces bit flex and improves drilling stability for accurate, repeatable holes.

Suitable for

• Drilling holes in concrete for anchors and fixings
• Installing electrical conduits and plumbing pipes through masonry
• On-site renovation and retrofit work in buildings
• General construction tasks requiring precise 8 mm holes in solid substrates

Key specifications

• Diameter: 8 mm
• Overall length: 160 mm
• Shank type: SDS Plus (for rotary hammer drills)
• Tip: carbide-tipped for enhanced wear resistance
• Flute type: spiral for efficient dust extraction
• Primary materials: intended for concrete, masonry and stone

How to use

Mount the bit into an SDS Plus-compatible rotary hammer according to the tool manufacturer's instructions until it locks in place. Use a rotary hammer in hammer-drilling mode when working in concrete or masonry. Start drilling at low speed to establish the position, then apply steady forward pressure and allow the tool to do the work; avoid excessive side pressure. Withdraw the bit periodically to clear dust from the hole and maintain cutting efficiency. For deeper holes, use extensions or appropriately long bits rather than overworking a short bit.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, dust mask and hearing protection. Match drill speed and impact settings to the substrate hardness, and ensure the rotary hammer is compatible with SDS Plus shanks. For clean holes and longer bit life, remove dust frequently and avoid overheating by pausing between long drilling runs.
