## Summary description

Irwin 10502027 is a single twist drill bit designed for use with a rotary hammer. It has a drill diameter of 1.8 cm and comes as one piece. Suitable for drilling tasks that require a standard twist bit profile when used in compatible rotary hammer tools; suitable for general drilling applications where this diameter and bit type are required.

## Long description

Irwin 10502027 is a single twist drill bit designed for use with SDS rotary hammers, with a drill diameter of 1.8 cm and supplied as one piece. The bit features a patented extra-short carbide tip and a new single-flute profile that together improve chip evacuation, reduce clogging and speed up drilling in concrete and masonry. The shank is compatible with SDS rotary hammers and the tip is brazed at high temperature for enhanced heat resistance and long life.
Advantages
The patented extra-short carbide tip concentrates approximately 80% of the workload on the head, enabling more aggressive concave cutting angles and self-centering behavior for easier control. Brazing at around 1000° Celsius with a bronze brazing paste produces a robust bond between tip and body, increasing durability. The single-flute design provides about 28% greater capacity for waste removal, clearing dust directly into the flute and reducing the risk of clogging. Combined, these features deliver up to 20% faster drilling while maintaining durability.
Suitable for
Drilling holes in concrete for anchors and dowels
Creating fixings in masonry and brickwork
Professional and DIY rotary-hammer drilling tasks requiring a 1.8 cm bit
Key specifications
Type: Twist drill bit with single flute
Drill diameter: 1.8 cm
Overall length: 210 mm
Tip: Extra-short carbide tip, brazed at high temperature
Flute: Single flute for improved chip evacuation
Suitable materials: Concrete, masonry
Compatibility: SDS rotary hammer shank
Quantity: 1 piece
How to use
Install the bit into an SDS-compatible rotary hammer according to the tool manufacturer’s instructions, ensuring the shank is fully engaged and locked. Select the appropriate drill mode and apply steady forward pressure; the patented short carbide tip and single flute will assist with self-centering and efficient dust removal. Periodically withdraw the bit during long holes to clear accumulated debris and allow the tip to cool, especially when drilling deep or in abrasive materials.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves, hearing protection) and a dust extraction system where possible. For best performance, match hammer speed and impact settings to the material being drilled and avoid excessive force that can overheat the tip. Replace the bit when wear reduces cutting efficiency or when the tip shows signs of damage.
