## Summary description

Irwin 10501945 is a single 5 mm twist drill bit designed for use with rotary hammers. This metal-cutting rotary drill accessory provides a standard-diameter cutting tip for drilling tasks. Supplied as one piece, it is suitable for precision drilling and general-purpose hole making in materials compatible with twist bits when used in a rotary-hammer drill.

## Long description

Irwin 10501945 is a single 5 mm twist drill bit designed for use with rotary hammers. Engineered for drilling in concrete and masonry, this accessory combines a patented extra-short carbide tip with a new single-flute geometry to deliver faster, more efficient drilling. Supplied as one piece with an SDS-compatible shank, the 5 mm diameter bit is intended for precision hole making and general-purpose work where twist bits are appropriate for use in rotary-hammer drills.
Advantages
The patented extra-short carbide tip transfers 80% of the workload to the head for improved durability and higher cutting speed while its concave, aggressive cutting angles increase penetration. The design clears dust directly into the flute to reduce clogging and features self-centering properties for easier control and straighter holes. A brazing process carried out at 1000°C with a bronze paste ensures a strong bond between tip and body for extended bit life. The new single-flute profile offers approximately 28% greater waste-removal capacity, and combined with the shorter tip enables up to 20% faster drilling compared with conventional designs.
Suitable for
 Drilling 5 mm holes in concrete
 Anchors and fastener installation in masonry
 Light-duty construction and renovation tasks
 Precision hole preparation where an SDS rotary hammer is used
Key specifications

 Overall length: 110 mm
 Tip: extra-short carbide, brazed at high temperature

How to use
Install the Irwin 5 mm twist drill bit into the SDS-compatible chuck of a rotary hammer according to the tool manufacturer's instructions. Select rotary hammer mode suitable for drilling in concrete or masonry and position the bit at the marked drilling point. Apply steady, moderate pressure while allowing the tool and bit geometry to do the cutting; avoid excessive axial force that can reduce tip life. Withdraw the bit periodically to clear accumulated dust if drilling deeper holes, and replace the bit when wear affects drilling performance.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. For best results in reinforced concrete, use progressive drilling techniques and check for rebar before continuing. Store the bit in a dry place to prevent corrosion and inspect the brazed tip before use; replace the bit if the carbide tip is chipped or detached.
