Masonry drill bit Irwin 8 x 120 mm – carbide-tipped SDS-compatible length 120mm, diameter 8mm

The Irwin masonry drill bit 8 x 120 mm is a carbide-tipped SDS-compatible drilling accessory designed for creating clean holes in brick, concrete and block materials. With an overall length of 120 mm and an 8 mm cutting diameter, this bit is intended for use with hammer drills and rotary hammers to install anchors, plugs and through-holes. The carbide tip provides improved wear resistance and consistent drilling performance across typical masonry surfaces.

Advantages

This drill bit combines a hardened steel body with a precision carbide tip to extend service life when used in abrasive masonry. Its SDS-compatible shank enables fast, secure engagement with compatible hammer drills and ensures reliable power transfer during percussion drilling. The 120 mm overall length gives sufficient reach for most fixing and anchor installation tasks while the 8 mm diameter matches common fasteners and plugs.

Suitable for

• Drilling anchor and plug holes in brick walls
• Creating through-holes in concrete and blockwork
• General masonry fixing for electrical boxes, brackets and conduit

Key specifications

• Material tip: carbide for increased wear resistance
• Shank type: SDS-compatible for use in hammer drills and rotary hammers
• Overall length: 120 mm
• Cutting diameter: 8 mm
• Intended use: percussion drilling in masonry materials (brick, concrete, block)

How to use

Secure the drill bit in the hammer drill’s chuck or SDS holder according to the tool manufacturer’s instructions. Select the hammer or rotary hammer mode for masonry drilling and set the drilling speed appropriate for the substrate. Position the bit on the marked drilling point, apply steady axial pressure and allow the tool’s percussion action to advance the bit through the material. Withdraw the bit periodically to clear dust and debris from the hole, and finish to the required depth for anchors or through-fixing.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask. For harder concrete or reinforced areas, use steady, moderate pressure and avoid excessive force. Replace the bit when cutting performance diminishes or when the carbide tip shows visible wear to maintain hole quality and reduce tool strain.
