Masonry drill bit Irwin 10 x 140 mm, carbide tip for concrete and brick

Masonry drill bit Irwin 10 x 140 mm, carbide tip for concrete and brick is a purpose-built drilling accessory for creating clean holes in concrete, brick and general masonry. With a 10 mm working diameter and 140 mm overall length, the bit provides sufficient reach for common installation and fastening tasks. The carbide tip is designed to withstand abrasive materials and maintain cutting performance over repeated use, delivering consistent hole quality for anchors, screws and through-fixings.

Advantages

The carbide tip ensures improved wear resistance and longer service life compared with standard high-speed steel bits when used in masonry. The 140 mm length offers extended reach without compromising bit stability, while the 10 mm diameter is a common size for fixings and anchor bolts. The bit is suitable for use in hammer drilling modes and is compatible with rotary and SDS-plus tools where the shank design allows, providing efficient material removal and reduced clogging during drilling.

Suitable for

• Drilling anchor holes in concrete and brick
• Installing wall plugs, anchors and through-fixings
• Electrical and plumbing conduit penetrations through masonry
• General renovation and construction drilling tasks

Key specifications

• Diameter: 10 mm
• Overall length: 140 mm
• Tip: carbide cutting tip for masonry
• Application: concrete, brick and masonry materials
• Suitable drill modes: rotary hammer/hammer drilling and rotary where compatible

How to use

Select a drill with compatible bit retention and hammer function if required. Mark the drilling location and start drilling at low speed to establish the hole, then apply steady pressure and increase speed or engage hammer mode for masonry. Periodically withdraw the bit to clear dust and prevent overheating; use water sparingly only if recommended for the specific task. Secure the workpiece or area, wear appropriate eye and hearing protection, and follow the drill manufacturer's safety instructions.

Usage recommendations

Use the bit for standard 10 mm anchor and fixing sizes, avoid excessive side load to prevent premature wear, and replace the bit when cutting performance degrades or the carbide tip shows visible damage. Store in a dry place and keep the shank clean to ensure reliable seating in the drill chuck or SDS-plus holder.
