Drill bit for concrete STANLEY STA58502 triangular shank 5 mm

Concrete drill bit STANLEY STA58502 with a 5 mm diameter and triangular shank is designed for drilling into concrete and masonry. The carbide tip and hardened body provide controlled penetration in dense substrates when used with compatible hammer or rotary drills. The triangular shank improves grip in standard chucks and reduces rotation slip, making it suitable for creating small anchoring holes and mounting fixtures in light construction or repair tasks.

Advantages

The triangular shank ensures a more secure fit in the drill chuck, reducing slippage under load and improving drilling accuracy. A hardened shaft and a wear-resistant tip extend service life in abrasive masonry materials. Its compact 5 mm diameter enables precise holes for anchors, screws and dowels while keeping material removal minimal. The bit is compatible with common hammer and rotary drilling actions when the chuck accepts triangular shanks.

Suitable for

• Drilling small anchoring holes in concrete and brick
• Installing fixtures, fittings and wall anchors
• Light renovation and repair work on masonry
• Preparation of holes for screws, dowels and light fasteners

Key specifications

• Diameter: 5 mm
• Shank type: triangular (for secure grip in compatible chucks)
• Material: hardened steel body with wear-resistant tip suitable for concrete and masonry
• Intended use: hammer and rotary drilling into masonry and concrete
• Typical hole size: small anchoring and fastening holes

How to use

Select a drill that accepts triangular shanks and set the appropriate hammer or rotary mode for masonry. Mark the drilling point and position the bit perpendicular to the surface. Start at low speed to seat the tip, then increase speed and apply steady pressure; allow the tool to do the work rather than forcing the bit. Periodically withdraw the bit to clear dust from the hole and prevent binding. For deeper holes, repeat clearing cycles to maintain drilling efficiency.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and dust mask. Match drill speed and hammer action to the material; avoid excessive side pressure to prevent bit breakage. Replace the bit when wear or tip damage reduces drilling performance to maintain hole accuracy and safety.
