## Summary description

Professional drill bit Dedra WP1646 with 1.6 cm diameter and 40 cm working length designed for drilling into concrete, brick, stone and aerated concrete. Single-piece set (1 pc). Suitable for rotary and hammer drills where long-reach drilling is required for installations, anchors, rebar clearance and masonry work.

## Long description

Professional drill bit Dedra WP1646 with a 1.6 cm diameter and 40 cm working length designed for drilling into concrete, brick, stone and aerated concrete. This single-piece 1 pc bit is intended for tasks that require extended reach and stable drilling performance in masonry materials. The bit's geometry and length make it suitable for creating holes for anchors, through-holes, rebar clearance and installations where standard-length bits are not sufficient.
Advantages
The drill bit offers a long working length for deep or hard-to-reach holes while maintaining rigidity for accurate drilling. Its tip and flute design are optimized for efficient dust removal and sustained cutting in dense masonry. Made from a single-piece construction, the bit delivers consistent concentricity and reduces the risk of breakage at connection points. Compatibility with both rotary and hammer drills ensures versatile use on a range of jobsites.
Suitable for
 Drilling holes for anchors and sleeves in concrete and brick
 Creating through-holes in stone and masonry walls
 Installing rebar or creating clearance holes in reinforced structures
 Working with aerated concrete where extended reach is required
 Situations requiring a single long bit instead of multiple extensions
Key specifications
 Diameter: 1.6 cm
 Working length: 40 cm
 Material compatibility: concrete, brick, natural stone, aerated concrete
 Construction: single-piece solid bit for improved rigidity
 Suitable drill types: rotary drills and hammer drills (percussion)
How to use
Secure the bit in the drill chuck according to the drill manufacturer's instructions and select the appropriate drilling mode (rotary or hammer) based on the material. Mark the drilling point, start at low speed to position the tip, then increase speed and apply steady pressure. Periodically withdraw the bit to clear dust and debris from the hole and flutes, which improves cutting efficiency and prevents overheating. For deep holes, maintain alignment and allow the drill to do the cutting rather than forcing the bit.
Usage recommendations
Use appropriate personal protective equipment (safety goggles, hearing protection and dust mask) when drilling masonry. Match drill speed and hammer action to the material: lower speeds for dense stone, standard hammer setting for concrete and brick, and moderate speed for aerated concrete. Inspect the bit before use for wear or damage and replace if the tip is chipped or cutting performance declines. For best results with long-reach drilling, use a drill with sufficient power and a stable grip to control torque.
