Drill bit for concrete Irwin cylindrical 8 mm (10501907)

Irwin cylindrical drill bit for concrete, 8 mm diameter, is designed for drilling clean, precise holes in concrete and masonry. The bit features a solid carbide tip engineered for durability and performance when used with hammer and rotary drills that accept straight cylindrical shanks. It is intended for creating 8 mm holes for anchors, dowels and various fastenings in construction, installation and repair tasks.

Advantages

The carbide tip ensures improved wear resistance and consistent cutting action in abrasive materials like concrete and brick. Its conventional cylindrical shank provides compatibility with a wide range of hammer and rotary drills that accept straight shanks, allowing quick tool changes and secure clamping. The 8 mm diameter produces standardized hole sizes suitable for common anchors and fixings, offering predictable fit and reliable holding strength.

Suitable for

• Drilling holes for wall anchors, plugs and dowels in concrete and masonry
• Installation of fixtures such as shelves, brackets and railings
• Repair and renovation works requiring precise 8 mm holes
• General construction and trade tasks with hammer or rotary drills

Key specifications

• Drill type: masonry/concrete drill bit with carbide tip
• Diameter: 8 mm
• Shank style: straight cylindrical shank for standard drill chucks
• Tip material: solid carbide for enhanced wear resistance
• Intended use: hammer drilling and rotary drilling in concrete, brick and masonry

How to use

Choose a drill and chuck that accept straight cylindrical shanks and secure the bit firmly in the chuck. Mark the drilling position and, when applicable, use a center punch to prevent walking. For concrete and masonry, use the hammer function on the drill while applying steady, even pressure. Start at low speed to establish the hole then increase speed as the bit advances. Periodically withdraw the bit to clear dust from the hole and reduce heat build-up. For deep holes, use peck drilling to maintain performance and extend bit life.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and a dust mask. Match the 8 mm hole size to compatible anchors or fastenings, and select drill speed and hammer settings according to material hardness to maximize bit life and hole quality.
