Masonry Drill Bit Irwin 6 x 100 mm

Masonry drill bit Irwin 6 x 100 mm is a carbide-tipped drill designed for drilling into masonry materials such as concrete, brick and natural stone. With a 6 mm cutting diameter and 100 mm overall length, this bit is intended for use with hammer drills and rotary hammers to create clean, accurate holes for anchors, wall plugs and fixing fasteners during construction and renovation tasks.

Advantages

The carbide tip provides durable cutting performance and improved wear resistance when penetrating hard substrates. The shank and body are engineered to maintain concentricity, reducing wobble and ensuring straight holes. The 100 mm length offers sufficient working depth for common fastening tasks while remaining compact for ease of handling. Compatible with standard hammer-drill chucks, the bit is suitable for frequent onsite use and replacement where predictable hole quality is required.

Suitable for

• Drilling holes for wall plugs and anchors in concrete and brick
• Installing fasteners for fixtures, shelves and electrical boxes
• General renovation and construction where precise masonry holes are needed

Key specifications

• Cutting diameter: 6 mm
• Overall length: 100 mm
• Tip material: carbide
• Intended materials: concrete, brick, natural stone
• Tool compatibility: hammer drills and rotary hammers with compatible chuck

How to use

Select an appropriate drill speed and hammer setting on the drill according to the substrate. Mark the drilling point, position the bit perpendicular to the surface and begin drilling with steady, even pressure. Withdraw the bit periodically to clear dust from the hole for improved cutting efficiency and hole quality. For through-holes or deeper anchors, verify depth visually or with a depth stop on the drill.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and a dust mask. For reinforced concrete, verify rebar location before drilling. Replace the bit when the carbide tip shows visible wear or decreased drilling performance to maintain hole accuracy.
