Drill Bit Irwin for Concrete Cylindrical 5 mm (10501897)

Cylindrical concrete drill bit Irwin, 5 mm diameter, is engineered for drilling into concrete, brick and similar masonry materials. The straight (cylindrical) shank fits standard chucks on hammer drills and rotary drills, allowing use in percussion and non-percussion modes depending on the tool. This 5 mm carbide-tipped bit is intended for creating small anchor, dowel and fixing holes during installation and light construction or renovation tasks.

Advantages

The Irwin 5 mm concrete drill bit combines a carbide cutting tip and a robust flute design to provide effective chip evacuation and consistent hole quality in masonry. Its straight shank enables quick mounting in common drill chucks without an adapter, and the compact 5 mm diameter is suitable for precise anchoring and fixture work. The bit's geometry is optimized for reducing walking at the drill start and for extending service life under typical DIY and professional light-use conditions.

Suitable for

• Drilling small-diameter anchor and dowel holes in concrete and brick
• Installing fittings, hangers and light fixtures
• Light repair, renovation and maintenance tasks on masonry
• Use with hammer drills and rotary drills that accept straight shank bits

Key specifications

• Drill bit type: masonry/concrete bit with carbide tip
• Diameter: 5 mm
• Shank: straight (cylindrical) shank for standard chucks
• Suitable materials: concrete, brick, block and similar masonry
• Typical use: anchor, dowel and fixture hole drilling

How to use

Select an appropriate drill and chuck that securely holds a 5 mm straight-shank bit. For concrete and hard masonry, use the hammer function on your drill where available; for delicate locations or thin masonry, use rotary mode to avoid damage. Mark the drilling position, start at low speed to prevent bit walking, then increase speed and apply steady, moderate pressure. Periodically withdraw the bit to clear dust and debris from the hole. Keep the bit straight to ensure accurate holes and replace the bit when cutting performance declines.

Usage recommendations

Use suitable personal protective equipment such as safety goggles, gloves and a dust mask when drilling masonry. For deeper holes, clear dust frequently and consider using water sparingly only if the drill and site conditions allow. Match anchor and dowel sizes to the 5 mm hole diameter and follow manufacturer instructions for fixing installation.
