Drill bit STANLEY STA54047 for rotary hammer, diameter 12 mm, length 166 mm, 1 pc

STANLEY STA54047 drill bit for rotary hammer, diameter 12 mm and overall length 166 mm, supplied as a single piece. Designed for use with compatible hammer-drill systems, this rotary hammer bit is intended for drilling into concrete, masonry and similar mineral-based substrates. The specification of diameter and length helps select the appropriate core size for construction, installation and renovation tasks where a durable masonry drill is required.

Advantages

The drill bit offers a standardized 12 mm diameter and 166 mm length that suit common anchoring and through-drilling needs in building work. Its SDS-plus shank provides secure engagement with rotary hammer chucks and allows quick bit changes. The geometry and carbide tip are engineered for efficient drilling in concrete and masonry, delivering consistent hole size and reducing breakage risk when used within appropriate operating parameters.

Suitable for

• Drilling holes for anchors and plugs in concrete and masonry
• Through-drilling for cabling and conduit installation in walls
• Renovation and construction where standard 12 mm holes are required
• Use with rotary hammers that accept SDS-plus shanks

Key specifications

• Drill diameter: 12 mm
• Overall length: 166 mm
• Shank type: SDS-plus
• Intended material: concrete, masonry and similar mineral substrates
• Quantity: 1 piece

How to use

Fit the SDS-plus shank securely into the rotary hammer chuck until it locks. Select an appropriate hammer mode and speed for concrete or masonry, apply steady axial pressure and allow the bit to cut without excessive force. Withdraw periodically to clear dust from the hole and prevent overheating. For through-holes, ensure correct alignment and mark drilling points before starting. Always select drill settings and PPE appropriate to the worksite.

Usage recommendations

Use with rotary hammers specified to accept SDS-plus bits and match the drilling mode to the substrate. Wear eye, ear and respiratory protection when drilling concrete or masonry. For long or deep holes, remove the bit occasionally to clear dust and inspect the cutting tip; replace the bit if the carbide tip shows significant wear or damage.
