The Irwin 10501955 twist drill bit is a reliable accessory designed specifically for rotary hammer applications, featuring a 6 mm diameter and a total length of 160 mm. Built to handle demanding construction materials like concrete and masonry, this drill bit delivers consistent performance, structural durability, and efficiency for both professional contractors and home improvement enthusiasts. Equipped with a patented extra short carbide tip and a high-heat resistant brazing process conducted at 1000° Celsius, it provides high heat resistance and longevity during intensive drilling tasks.

Advantages

This drill bit features a patented extra short carbide tip that takes on eighty percent of the workload, ensuring significantly higher durability and speed during operation. The head design includes self-centering capabilities for easier control and more aggressive concave cutting angles that allow for faster drilling through tough surfaces. The unique single flute design offers twenty-eight percent greater capacity, ensuring highly efficient waste removal and clearing drilling dust directly into the flute to minimize the risk of clogging. Additionally, the specialized brazing method using bronze paste creates a secure bond with high heat resistance, resulting in an extended operating life for the bit.

Suitable for

• Drilling 6 mm holes in concrete
• Masonry drilling projects
• Professional construction and renovation work
• Home improvement and DIY drilling tasks
• Applications requiring SDS rotary hammers

When it may not be suitable

This drill bit is not designed for drilling in wood, plastics, or soft metals due to its specialized carbide tip geometry intended for masonry and concrete. It is also not compatible with standard drill chucks that do not support SDS shank systems.

Key specifications

• Twist drill bit type
• Drill bit diameter: 6 mm
• Total length: 160 mm
• Compatible with all SDS rotary hammers
• Suitable for concrete and masonry materials

How to use

Insert the shank of the Irwin twist drill bit securely into your SDS rotary hammer until it locks into place. Ensure the tool is unplugged or the battery is removed before changing bits. Position the self-centering tip at the exact spot you wish to drill, maintaining a firm and perpendicular grip on the rotary hammer. Apply steady forward pressure while operating the tool, allowing the percussion mechanism and the aggressive cutting angles to perform the work without forcing the drill. Periodically retract the bit slightly during deep holes to assist with dust clearance.

What to consider before purchase

• Verify that your drilling tool is compatible with SDS shank systems
• Confirm that a 6 mm diameter hole size matches your project requirements
• Assess the primary materials you will be drilling, as this bit is optimized specifically for concrete and masonry

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and ear protection, when operating a rotary hammer. Inspect the carbide tip and shank for wear or damage before each use to ensure safe and efficient operation.
