Drill bit Irwin for concrete cylindrical 12 mm model 10501914

Irwin cylindrical concrete drill bit, 12 mm diameter, model 10501914, is engineered for clean and reliable drilling in concrete and common masonry materials. The solid cylindrical shank is compatible with standard drill chucks and allows secure fastening in rotary drills and hammer drills. The geometry of the cutting tip and the material composition provide effective penetration into dense substrates and consistent hole quality for fixing anchors, dowels, cable glands and pipe passages in construction and renovation works.

Advantages

This 12 mm concrete drill bit offers a durable carbide-tip design and a robust body that resists wear during repetitive drilling. The cylindrical shank simplifies bit changes and fits most standard drill chucks without an adapter. Its cutting profile reduces walking at the start of drilling, improving accuracy, while the optimized flute design helps remove debris to maintain drilling speed and reduce heat build-up.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Making passages for electrical conduits and plumbing
• Installing fixings in masonry walls and floors
• Renovation and light to medium construction drilling tasks

Key specifications

• Diameter: 12 mm
• Shank type: cylindrical (straight shank) suitable for standard chucks
• Intended materials: concrete and common masonry
• Tip type: carbide or carbide-tipped geometry for masonry drilling
• Typical use: rotary drilling and hammer drilling

How to use

Secure the drill bit in the chuck of a rotary or hammer drill, ensuring the shank is fully inserted and tightened. Position the drill perpendicular to the surface and start drilling at low speed to establish a precise starting point, then increase speed and apply steady pressure appropriate to the substrate. For deeper holes, periodically withdraw the bit to clear dust and debris from the hole and the flute. Use hammer mode only when required for dense concrete; for softer masonry, rotary mode may be sufficient.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and a dust mask. Use suitable anchor or dowel sizes for a 12 mm hole and verify drill speed and percussion settings with the drill manufacturer’s guidance. Keep the bit clean and inspect for wear or tip damage; replace the bit if consistent performance declines.
