Drill Bit Irwin for Concrete, Cylindrical Shank 13 mm, model I-10501859

Irwin concrete drill bit with a cylindrical (straight) shank, 13 mm cutting diameter, model I-10501859. This drill bit is designed for drilling into concrete, brick and other masonry materials with hammer or rotary drills that accept cylindrical shanks. The 13 mm diameter is suitable for making holes for standard anchors, conduits and fastenings during construction and renovation work. The bit’s geometry and carbide tip are engineered to penetrate hardened substrates while maintaining drilling accuracy and minimizing wear under normal working conditions.

Advantages

The Irwin 13 mm concrete drill bit provides stable drilling performance in masonry thanks to its carbide cutting tip and straight shank compatible with most standard chucks. Its 13 mm diameter offers a balance between hole size and drill control for anchor and fastening installation. The bit is manufactured to consistent dimensions to ensure repeatable hole sizes and reliable fit for commonly used anchors and fittings.

Suitable for

• Drilling holes for wall anchors and plugs in concrete and brick
• Preparing passages for electrical conduits and pipes in masonry
• Installing mechanical fastenings and fixtures in construction and renovation projects
• General purpose masonry drilling with hammer or rotary drills that accept cylindrical shanks

Key specifications

• Cutting diameter: 13 mm
• Shank type: cylindrical (straight) shank compatible with standard drill chucks
• Intended material: concrete, brick and masonry
• Tip type: carbide cutting tip designed for masonry
• Typical use: hammer drilling and rotary drilling in masonry

How to use

Mark the drilling point and secure the workpiece or ensure stable positioning against the masonry surface. Select a hammer or rotary drill that accepts cylindrical shanks and insert the 13 mm Irwin bit firmly into the chuck, tightening according to the drill manufacturer’s instructions. Use hammer mode for reinforced concrete or hard masonry, and rotary mode for softer brick or block where appropriate. Apply steady pressure, allow the bit to work without forcing, and periodically withdraw to clear dust and debris for efficient cutting and longer bit life.

Usage recommendations

For consistent results, use appropriate personal protective equipment (eye and hearing protection and dust mask) and keep the drill perpendicular to the surface. Use reduced speed and increased percussion for reinforced concrete, and clear dust from the hole frequently. Match hole depth to anchor specifications and avoid excessive lateral force to reduce tip wear and prevent shank damage.
