Drill bit STANLEY STA58510 – 9 mm triangular concrete drill bit

STANLEY STA58510 – 9 mm triangular concrete drill bit is engineered for drilling into concrete and masonry. The 9 mm diameter and triangular cross-section deliver stable engagement with drill chucks and reduced slippage during operation. Intended for use with hammer drills and rotary drills, this drill bit is suitable for creating anchor holes, fixing fixtures, and general masonry drilling in construction, renovation, and repair projects.

Advantages

The triangular cross-section provides improved grip in chucks and enhances bit stability while drilling, helping to maintain a straight hole and consistent drilling speed. Precision-ground flutes and a hardened tip ensure effective material removal and wear resistance during repeated use in concrete and masonry. The standard 9 mm size offers compatibility with common anchors and fixings, making the bit a practical choice for professional and DIY applications.

Suitable for

• Drilling anchor holes in concrete and block walls
• Installing fixtures, brackets and fasteners in masonry
• General repair and renovation work on construction sites
• Use with hammer drills and rotary drills for medium-duty masonry tasks

Key specifications

• Diameter: 9 mm
• Cross-section: triangular for improved chuck grip and stability
• Intended materials: concrete, masonry, concrete block
• Suitable drill types: hammer drills and rotary drills
• Typical applications: anchor holes, fixture installation, renovation tasks

How to use

Secure the drill bit in the chuck, ensuring the triangular shank seats correctly to minimize slippage. Select an appropriate drilling mode — hammer mode for solid concrete, rotary for softer masonry as required — and set a moderate speed suitable for the drill and bit size. Start drilling at a steady pressure, periodically retracting the bit to clear dust and debris from the hole to maintain cutting efficiency. After reaching the desired depth, withdraw the bit while the drill is running briefly to remove remaining dust, then clean and inspect the bit before storage.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and a dust mask when drilling into concrete. Match drill speed and hammer action to the material and avoid excessive lateral force to prolong bit life. Replace the bit if the tip becomes rounded or wear significantly reduces drilling performance.
