## Summary description

DeWalt DT9448 masonry drill bit designed for use with a rotary hammer. Single-piece set with a drill diameter of 4.5 cm suitable for drilling into masonry materials such as brick, stone and concrete. Intended for professionals and DIYers requiring a robust bit for heavy-duty holemaking in construction, renovation and installation tasks.

## Long description

DeWalt DT9448 masonry drill bit for rotary hammer is a single-piece SDS‑max bit with a 45 mm diameter designed for drilling into masonry materials including brick, stone and concrete. Built for use with compatible rotary hammers, this heavy‑duty bit provides stable performance for construction, renovation and installation tasks where larger diameter holes are required.
Advantages
The bit features an advanced solid two‑cutter carbide tip flanked by two additional cutting tips, delivering fast and efficient material removal and improved hole quality. A four‑flute helix efficiently extracts dust and debris from the hole, helping maintain drilling speed and reduce heat build‑up. The one‑piece construction increases durability under high‑impact rotary hammer operation and reduces the risk of tip separation.
Suitable for
 Drilling large diameter holes in concrete
 Creating openings in brick and stone for anchors and inserts
 Heavy‑duty installation work in construction and renovation
 Professional trade use with SDS‑max rotary hammers
Key specifications
 Shank type: SDS‑max compatible
 Diameter: 45 mm
 Construction: one‑piece solid steel body
 Tip: two‑cutter carbide tip with two auxiliary cutting tips
 Flute design: four‑flute helix for efficient dust removal
 Intended materials: concrete, brick, natural stone and masonry
How to use
Install the bit securely in an SDS‑max rotary hammer according to the tool manufacturer's instructions. Select an appropriate drill speed and impact setting for the material being drilled. Begin drilling with steady axial pressure, allowing the hammer action and carbide tip to cut efficiently; avoid excessive force that can overload the bit. Periodically withdraw the bit to clear dust and debris, which helps maintain drilling speed and prolong bit life.
Usage recommendations
Use the bit with appropriate personal protective equipment, including eye and hearing protection. For extended drilling in reinforced concrete, use a reduced feed rate and remove accumulated debris regularly. Store the bit dry and protected to prevent corrosion when not in use.
