Drill bit STANLEY STA54122 for rotary hammer, Ø 12 mm, length 460 mm, 1 pc

STANLEY STA54122 drill bit for rotary hammer, Ø 12 mm, length 460 mm, supplied as a single piece. This carbide-tipped masonry bit is designed to work with SDS-plus compatible rotary hammers for drilling into concrete and other masonry materials. Its 12 mm diameter and 460 mm total length make it suitable for through-drilling and for creating deep holes in walls, foundations or structural elements during construction and renovation work.

Advantages

The drill bit combines a long working length with a compact diameter to allow deep, precise holes without frequent repositioning. Its SDS-plus shank enables fast and secure tool fitting and efficient impact transfer from the rotary hammer to the tip. The carbide cutting tip offers wear resistance when used in concrete and similar masonry, helping preserve cutting performance over repeated use.

Suitable for

• Drilling through concrete walls and slabs
• Installing anchors and dowels in masonry
• Running cables or pipes through structural elements
• General renovation and construction drilling tasks

Key specifications

• Diameter: 12 mm
• Total length: 460 mm
• Intended materials: concrete and masonry
• Shank type: SDS-plus
• Quantity: 1 piece

How to use

Fit the drill bit into an SDS-plus compatible rotary hammer according to the tool manufacturer's instructions until it locks firmly. Mark the drilling point, start the hammer at low speed to create a starter recess, then increase speed and apply steady axial pressure while allowing the tool's percussion action to perform the cutting. Withdraw the bit periodically to clear dust from deep holes and prevent binding. Use appropriate drill speed and impact settings for the concrete hardness; do not use the bit in pure rotary mode without impact when working in masonry unless the tool and task require it.

Usage recommendations

Wear suitable personal protective equipment including eye protection, hearing protection and a dust mask. For cleaner and safer holes, use a vacuum dust extractor or periodically clear dust. Inspect the bit before use and replace it if the carbide tip is chipped or excessively worn. Match this 12 mm × 460 mm bit with an SDS-plus rotary hammer rated for long masonry drilling to ensure proper performance and tool life.
