Masonry drill bit Irwin 7 x 110 mm

The Irwin masonry drill bit 7 x 110 mm is engineered for drilling into masonry materials such as brick, concrete and block. With a 7 mm diameter and 110 mm overall length, this drill bit balances precision and reach for common installation and mounting tasks. Designed to be used with hammer drills, it provides controlled penetration and reliable hole accuracy for anchors, fixings and conduit runs in renovation and construction work.

Advantages

The solid carbide tip and flute geometry deliver efficient cutting and improved dust evacuation, reducing clogging during drilling. The 110 mm length gives sufficient working depth for most anchor and fastening applications while the 7 mm diameter matches standard anchor sizes. Constructed for durability, the bit maintains cutting performance through repeated use in masonry substrates and is compatible with standard hammer drill chucks.

Suitable for

• Drilling holes for wall anchors and plugs in brick and concrete
• Fixing fixtures such as shelves, brackets and conduit supports
• Creating passageways for cables and small-diameter piping through blockwork
• General renovation and building site tasks requiring reliable masonry drilling

Key specifications

• Diameter: 7 mm
• Overall length: 110 mm
• Material tip: carbide cutting tip (solid or brazed carbide)
• Suitable drill type: hammer drills / rotary hammer in percussion mode
• Typical applications: masonry, brick, concrete, block

How to use

Secure the drill bit in the hammer drill chuck according to the drill manufacturer’s instructions. Mark the drilling location and start at low speed to position the bit, then apply steady pressure and engage the hammer function for effective penetration into masonry. Withdraw the bit periodically to clear dust from the hole and prevent overheating. For deeper holes, drill in stages and clear debris between passes to maintain accuracy.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling into masonry. Match the 7 mm bit diameter to corresponding anchors or plugs, and select an appropriate drill speed and hammer setting for the material to prolong bit life and ensure accurate holes.
