Masonry Drill Bit Irwin 11x160mm

The Masonry Drill Bit Irwin 11x160mm is a high-performance drilling tool engineered by Irwin to deliver reliable and efficient results in demanding construction and home improvement tasks. Designed specifically for working with hard mineral surfaces, this masonry drill bit provides the precision and durability needed for consistent performance across various building materials.

Advantages

This drill bit offers exceptional durability and strength, allowing it to withstand the high impacts and pressures associated with drilling into dense substrates. The design ensures efficient debris clearance from the hole during operation, reducing friction and heat buildup to prolong the lifespan of the tool. Its precise geometry enables accurate centering and clean entry holes, minimizing the risk of bit wandering and ensuring professional results for both contractors and DIY users.

Suitable for

• Drilling holes in concrete for anchors and fixings
• Working with solid brick and hollow brick masonry
• Installing fixtures in natural and artificial stone surfaces
• General construction, renovation, and repair work

When it may not be suitable

This tool is not designed for drilling through metal, wood, or high-density structural steel, as these materials require different cutting geometries and material compositions. It is also unsuitable for core drilling large-diameter openings or working with reinforced concrete containing heavy rebar, which requires specialized carbide-tipped core bits.

Key specifications

• Diameter: 11 mm
• Total length: 160 mm
• Application: Concrete, brick, stone, and masonry materials
• Manufacturer: Irwin

How to use

Insert the drill bit securely into the chuck of a compatible rotary hammer or percussion drill, ensuring it is locked firmly in place. Position the tip of the bit perpendicularly against the marked surface of the masonry material. Apply steady, moderate pressure while operating the drill in hammer mode, allowing the tool to do the work without forcing it. Periodically retract the bit slightly during deep drilling to clear out accumulated dust and debris.

What to consider before purchase

• Verify that your drill features a compatible chuck to hold an 11mm diameter shank securely.
• Check the required hole depth and diameter for your specific fasteners or anchors to ensure the 160mm length is adequate.
• Confirm the primary material you will be drilling is masonry, concrete, or brick.

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and respiratory protection, when drilling into masonry to protect against dust and flying particles. Allow the drill bit to cool down periodically during extended use to maintain material integrity and performance.
