## Summary description

Long masonry drill bit Dedra WP1241 with a 1.2 cm diameter and 35 cm working length. Designed for drilling in concrete, brick, natural stone and aerated concrete.

## Long description

Long masonry drill bit Dedra WP1241 with a 1.2 cm diameter and 35 cm working length designed for drilling in concrete, brick, natural stone and aerated concrete. This single-piece drill bit is intended for use with rotary and hammer drills where extended reach and deep hole capability are required for construction and repair jobs. The bit’s length and working flute geometry support efficient chip removal and stable drilling in dense masonry materials.
Advantages
The 35 cm working length provides extended reach for drilling deep holes or accessing recessed fixing points without changing to extension rods. A 1.2 cm diameter strikes a balance between sufficient anchoring capacity and manageable drilling effort. The one-piece construction reduces the risk of breakage at joints and increases tool rigidity for more accurate hole alignment. The tip and flute design are optimized for masonry work, allowing effective dust and debris evacuation during rotary or hammer drilling.
Suitable for
 Drilling anchor and dowel holes in concrete and reinforced concrete
 Making through-holes and fixing points in brick walls
 Installing anchors and fasteners in natural stone surfaces
 Working with aerated concrete blocks where deeper holes are required
Key specifications
 Material compatibility: concrete, brick, natural stone, aerated concrete
 Shank type: straight shank suitable for standard drill chucks
 Diameter: 12 mm (1.2 cm)
 Working length: 350 mm (35 cm)
 Construction: single-piece solid design for rigidity
How to use
Secure the drill bit firmly in the drill chuck and set the drill to the appropriate mode: rotary or hammer depending on material hardness. Mark the drilling position and start at low speed to create a starter indent, then increase speed and apply steady pressure. For deep holes, periodically withdraw the bit to clear dust and chips and to prevent overheating. Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry.
Usage recommendations
For optimal performance, use the bit in a drill with sufficient power and an appropriate chuck size for the shank. When drilling reinforced concrete, ensure correct alignment and avoid excessive lateral force. Clean holes before inserting anchors and avoid using excessive heat or lubricant, which can reduce effectiveness in masonry drilling.
