## Summary description

Irwin 10501981 is a single 10 mm twist drill bit designed for use with rotary hammers. The bit is suitable for drilling tasks requiring a 10 mm diameter hole and is supplied as one piece. Use cases include general drilling in compatible materials with a rotary hammer where a standard twist drill geometry is required.

## Long description

Irwin 10501981 is a 10 mm twist drill bit supplied as a single piece and designed for use with SDS rotary hammers. The bit features a patented extra-short carbide tip and a unique single-flute geometry that together provide faster penetration and efficient dust evacuation. Constructed with a high-temperature brazed carbide tip and a shank compatible with SDS rotary hammers, this drill bit is intended for drilling 10 mm holes in concrete and masonry where a standard twist-drill shape is required.
Advantages
The patented extra-short carbide tip directs up to 80% of the workload to the head, improving durability and maintaining cutting efficiency. The head’s self‑centering geometry and more aggressive concave cutting angles enable easier control and faster drilling, with up to 20% higher drilling speed compared to conventional designs. The brazed carbide tip is attached using a bronze brazing paste at approximately 1000° C to provide high heat resistance and longer life. The new single‑flute design increases debris capacity by about 28%, clearing dust into the flute to reduce clogging and support continuous cutting.
Suitable for
 Drilling 10 mm holes in concrete
 Drilling 10 mm holes in masonry
 General-purpose drilling with SDS rotary hammers when a twist-drill geometry is required
 Applications requiring fast penetration and efficient dust removal

How to use
Fit the Irwin 10 mm twist drill bit into the SDS rotary hammer according to the tool manufacturer’s instructions, ensuring the shank is securely locked. Select an appropriate drilling mode and start at low speed to establish a self‑centering entry, then increase speed and apply steady forward pressure while allowing the tool’s impact action to perform the cutting. Periodically withdraw the bit to clear accumulated dust, taking advantage of the single‑flute geometry to remove debris from the hole. Replace the bit if signs of wear or damage to the carbide tip appear.
Usage recommendations
Use appropriate personal protective equipment including eye, ear and respiratory protection when drilling concrete or masonry. Match drill speed and feed pressure to the material and tool capability; allow the patented short carbide tip and single flute to evacuate dust rather than forcing excessive pressure. Store the bit in a dry place and inspect the brazed tip before use for optimal performance and longevity.
