Drill Bit STANLEY SDS+ 6 mm STA54551 for Concrete

STANLEY SDS+ 6 mm STA54551 drill bit is designed for drilling clean, precise holes in concrete and masonry. The bit features an SDS+ shank that fits SDS+ rotary hammers and drills, a 6 mm diameter for medium-duty anchoring and through-holes, and a carbide tip that improves wear resistance and maintains cutting performance when working with abrasive materials like concrete and brick.

Advantages

The carbide tip provides longer life and consistent drilling accuracy compared with standard steel bits. The SDS+ shank enables quick, secure tool engagement and efficient hammer impact transfer for faster penetration in hard substrates. A 6 mm diameter balances hole size and tool control, making the bit suitable for common tasks such as anchor installation and electrical conduit passage without excessive material removal.

Suitable for

• Drilling holes in concrete and masonry for anchors and plugs
• Installing light fastenings and fixtures in renovation and construction
• Creating openings for electrical conduits and cable runs
• Medium-duty drilling where a 6 mm hole diameter is required

Key specifications

• Shank type: SDS+ compatible
• Diameter: 6 mm
• Tip material: carbide
• Intended material: concrete, brick and general masonry
• Application: rotary hammer drilling with hammer action

How to use

Select an SDS+ compatible rotary hammer or drill, insert the bit into the chuck until it locks, and set the tool to hammer or rotary-hammer mode as required. Position the bit perpendicular to the work surface, start at low speed to establish a pilot groove if needed, then apply steady pressure and allow the hammer action to drive the bit through the material. Withdraw occasionally to clear dust and reduce heat buildup. After drilling, clean the hole of debris before inserting anchors or fittings.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling. For faster drilling and longer bit life, work with a properly rated rotary hammer and avoid excessive side pressure; use water only if specified by the tool manufacturer for wet drilling applications.
