Drill bit for concrete STANLEY triangular 7 mm STA58506

Drill bit for concrete STANLEY triangular 7 mm STA58506 is a 7 mm concrete drilling accessory with a triangular cross-section tip designed for use with percussion drills and hammer drills. It is intended for creating clean, precise holes in concrete, masonry and natural stone where stability and efficient debris evacuation are required. The triangular geometry of the tip reduces clogging and helps maintain drilling direction, making the bit suitable for a range of on-site installation tasks.

Advantages

The triangular tip design improves chip removal and reduces bit walking, providing more stable drilling and consistent hole diameter. Manufactured by STANLEY to standard industry tolerances, the bit fits common 7 mm drilling requirements and performs reliably under impact drilling conditions. Its hardened steel body and reinforced tip maintain cutting performance across repeated use in abrasive materials such as concrete and masonry.

Suitable for

• Drilling mounting holes for anchors and fasteners in concrete and masonry
• Electrical conduit and outlet box installation in solid walls
• Plumbing pipe and fixture installation through stone or blockwork
• General construction and repair tasks requiring 7 mm holes in hard substrates

Key specifications

• Diameter: 7 mm
• Tip geometry: triangular cross-section for improved debris removal and stability
• Intended materials: concrete, masonry, natural stone
• Compatible tools: percussion drills and hammer drills
• Construction: hardened steel body with reinforced cutting tip

How to use

Select a percussion or hammer drill that supports a 7 mm bit and secure the drill bit in the chuck according to the tool manufacturer's instructions. Mark the drilling point, start at low speed to establish the hole, then apply steady pressure and use the drill's percussion mode for efficient penetration into concrete and masonry. Withdraw the bit periodically to clear accumulated debris and prevent overheating. After reaching the required depth, clean the hole of dust before inserting anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling concrete. For best results in reinforced concrete, verify rebar locations first and consider using a purpose-built rebar-cutting bit if necessary. Store the bit in a dry place to avoid corrosion and inspect the tip before use; replace the bit when wear reduces drilling accuracy or increases breakage risk.
