## Summary description

Dedra WP1231 drill bit, single piece with 1.2 cm diameter and 25 cm working length. Designed for drilling into concrete, brick, stone and aerated concrete. Suitable for masonry and construction tasks where a long reach and hard-material penetration are required.

## Long description

Dedra WP1231 drill bit is a single-piece masonry bit with a 1.2 cm diameter and a 25 cm working length, intended for drilling in concrete, brick, natural stone and aerated concrete. The long working length provides extended reach for through-holes, anchors and deep fastening tasks in construction and renovation projects. Designed to be used with compatible rotary or hammer drills, this bit is optimized for hard-material penetration while maintaining dimensional stability along its shaft.
Advantages
The 1.2 cm diameter and 25 cm working length combine to offer deeper drilling without changing bits frequently, reducing work interruptions on scaffolding or when accessing recessed areas. The single-piece construction provides consistent concentricity and improved vibration resistance during rotary and percussion drilling. Manufactured for use in masonry substrates, the bit preserves hole accuracy for secure anchoring and reliable fixture installation.
Suitable for
 Drilling anchor and through-holes in concrete walls and floors
 Creating fixing points in brick or natural stone
 Installing fasteners in aerated concrete blocks
 Construction and renovation tasks requiring extended reach
Key specifications
 Diameter: 1.2 cm
 Working length: 25 cm
 Material compatibility: concrete, brick, stone, aerated concrete
 Quantity: 1 piece
 Intended drill types: rotary and hammer drills (percussion)
How to use
Select a rotary or hammer drill compatible with masonry bits and secure the Dedra WP1231 in the chuck according to the drill manufacturer's instructions. Mark the drilling point, start at low speed to create a guide indent, then increase speed and apply steady pressure while allowing the bit to clear dust periodically. For deep holes, withdraw the bit occasionally to remove debris and avoid overheating. Use percussion mode on hammer drills for reinforced concrete or very hard masonry; use rotary-only mode for delicate stone or thin brick if necessary.
Usage recommendations
Wear appropriate personal protective equipment: safety glasses, hearing protection and dust mask. Match drill speed and feed pressure to the substrate hardness, and use anchor or fixing elements sized to the 1.2 cm hole. Inspect the bit for wear before use and replace if the cutting tip is damaged or drilling performance decreases.
