## Summary description

Dedra WP0841 is a single 8 mm drill bit with a 350 mm working length designed for drilling into concrete, brick, stone and aerated concrete.

## Long description

Dedra WP0841 is a single 8 mm diameter drill bit with a 350 mm working length, designed for drilling into concrete, brick, natural stone and aerated concrete. The bit is intended for use with rotary and hammer drilling tools and offers extended reach for deeper boreholes needed in installation and repair tasks. Its geometry and length make it suitable for creating anchor points, passing pipes or conduits and for general masonry work where a long-reach 8 mm hole is required.
Advantages
The 350 mm working length provides long reach without changing tools, while the 8 mm diameter matches common anchor and fastener sizes. The bit is optimized for masonry materials — concrete, brick, stone and autoclaved aerated concrete — ensuring consistent drilling performance in these substrates. Supplied as a single piece, the bit is compact for storage and straightforward to fit in standard SDS-plus or compatible chucks depending on the drill used.
Suitable for
Drilling anchor holes for bolts and fixings in concrete and brick
Creating passage holes for small pipes, conduits and cables
Repair and renovation tasks requiring deep or hard-to-reach holes
Masonry drilling in stone and aerated concrete walls
Key specifications
Drill diameter: 8 mm
Working length: 350 mm
Recommended materials: concrete, brick, natural stone, aerated concrete
Packaging: single piece
How to use
Select a drill with an appropriate chuck or SDS interface that accepts an 8 mm masonry bit and set the tool to rotary or hammer mode according to the substrate and manufacturer recommendations. Mark the drilling position, start at low speed to establish the point, then increase speed and apply steady pressure. Periodically withdraw the bit to clear dust and reduce heat build-up. For deep holes, remove debris more frequently to maintain cutting efficiency and to ensure correct hole depth.
Usage recommendations
Use appropriate personal protective equipment including safety glasses, dust mask and hearing protection. For reinforced concrete or uncertain conditions, check for embedded rebar before drilling. Match drill mode and speed to the material: rotary hammer mode for dense concrete, rotary mode for softer masonry and aerated concrete. If using an adapter or different chuck, ensure the bit is securely seated before operation.
