Drill bit Irwin Speedhammer Plus 20.0 mm x 1000 mm for concrete, model 10502042

Irwin Speedhammer Plus 20.0 mm x 1000 mm is a concrete drill bit designed for use with hammer drills and rotary hammers. With a 20.0 mm working diameter and a 1000 mm overall length, this SDS-compatible bit is engineered for drilling through reinforced and non-reinforced concrete. The tungsten carbide tip geometry and flute design promote efficient chip removal and stable drilling in through-holes, anchor installation and rebar drilling tasks common in construction and renovation.

Advantages

The drill bit features a durable tip geometry that maintains cutting performance and extends service life under repeated hammering. Its long 1000 mm length provides reach for deep boreholes and makes it suitable for installing long anchors or creating passage holes. Optimized flute design reduces clogging and improves dust evacuation, while the shank profile ensures reliable engagement with compatible hammer drill chucks.

Suitable for

• Drilling through-holes in reinforced and non-reinforced concrete
• Installing anchors and fixings in concrete walls and floors
• Creating deep boreholes for services, conduits or pipework
• Drilling near or through rebar when combined with appropriate technique

Key specifications

• Working diameter: 20.0 mm
• Overall length: 1000 mm
• Intended material: reinforced and non-reinforced concrete
• Tip material and design: tungsten carbide tip with optimized cutting geometry
• Flute design: engineered for improved chip removal and dust evacuation
• Drive type: shank compatible with hammer drill / rotary hammer systems

How to use

Select a hammer drill or rotary hammer compatible with the bit's shank and set the tool to hammer-drill mode. Mark the drilling position and secure the workpiece or ensure safe access. Start drilling at low speed to establish the bore, then increase to the recommended operating speed while maintaining steady pressure; avoid excessive lateral force. Periodically withdraw the bit to clear debris and allow cooling, especially when drilling deep holes. When approaching or encountering rebar, use controlled pressure and correct technique to avoid bit damage.

Usage recommendations

Use appropriate personal protective equipment: safety glasses, hearing protection and dust mask. For long or deep holes, remove debris frequently and let the bit cool to maintain life and drilling performance. Match drill diameter and length to anchor or conduit requirements and follow manufacturer guidance for anchor installation and drill press or hammer drill settings.
