Irwin 10501981 Twist Drill Bit for Rotary Hammer 1 cm Diameter

The Irwin 10501981 twist drill bit is engineered specifically for rotary hammers, featuring a 1 cm diameter and an overall length of 260 mm. Designed for professional construction and home improvement tasks, this twist drill bit ensures precise and efficient drilling in demanding masonry and concrete applications. It integrates a patented extra short carbide tip that takes on the majority of the workload to enhance durability and speed. The innovative single flute design provides greater capacity for efficient waste removal, making it a reliable accessory for intensive drilling tasks.

Advantages

This drill bit delivers 20 percent faster drilling compared to standard bits while maintaining high overall durability. The patented extra short carbide tip clears drilling dust directly into the flute, which significantly reduces the risk of clogging during operation. Its self-centering tip allows for easier tool control and features more aggressive concave cutting angles for accelerated penetration. Additionally, the high-temperature brazing process conducted at 1000 degrees Celsius ensures exceptional heat resistance and a secure bond between the tip and the bit body, extending the product lifespan.

Suitable for

• Drilling into concrete walls and structures
• Masonry and brickwork installation tasks
• Professional construction and renovation projects
• Home improvement applications requiring a rotary hammer

When it may not be suitable

This drill bit is specifically designed for use with rotary hammers and masonry materials, so it is not suitable for drilling into wood, plastic, or standard metals. Attempting to use this accessory in rotary-only drills without hammer action or on inappropriate materials will result in poor performance and potential damage to the bit.

Key specifications

• Drill bit type: Twist drill bit
• Drill bit diameter: 1 cm
• Length: 260 mm
• Shank compatibility: Fits all SDS rotary hammers
• Suitable materials: Concrete and masonry

How to use

Insert the shank securely into an SDS rotary hammer capable of accepting a 1 cm diameter bit. Ensure the tool is powered off and unplugged before changing accessories. Align the drill bit perpendicularly to the target surface of concrete or masonry. Activate the rotary hammer and apply steady, moderate pressure without forcing the tool, allowing the self-centering tip and efficient flute design to clear dust and penetrate the material smoothly.

What to consider before purchase

• Verify that your drilling tool is an SDS rotary hammer compatible with the 1 cm diameter and 260 mm length.
• Confirm that your primary application involves drilling into concrete or masonry rather than wood or metal.
• Assess the required hole depth to ensure the 260 mm length meets your project requirements.

Usage recommendations: Always wear appropriate personal protective equipment including safety glasses and respiratory protection when drilling into concrete or masonry. Allow the drill bit to cool down after extended heavy use before handling.
