## Long description

DeWalt DT9590 drill bit for rotary hammer, Ø 18 mm and length 450 mm, is designed for reliable drilling into masonry and concrete with SDS-compatible rotary hammer tools. Supplied as a single piece, this bit is intended for medium to deep hole drilling tasks encountered in construction, renovation and installation work. The carbide tip and flute geometry are matched to rotary hammer operation to remove debris efficiently and maintain drilling speed in dense materials.
Advantages
The drill bit offers consistent hole quality and durability when used with a suitable SDS rotary hammer. Its 18 mm diameter and extended 450 mm length allow reach into deeper workpieces without the need for extensions. Optimised flute design helps clear dust and chips, reducing binding and heat build-up during continuous drilling. The single-piece supply makes it easy to select and replace bits on site.
Suitable for
 Drilling anchor and through-holes in concrete and reinforced concrete
 Creating holes for fasteners in brick and blockwork
 Medium to deep hole drilling in renovation and construction projects
 Work with SDS-compatible rotary hammers
Key specifications
 Diameter: 18 mm
 Overall length: 450 mm
 Shank type: SDS-compatible shank for rotary hammers
 Tip material: carbide cutting tip for masonry and concrete
 Designed use: drilling in masonry, concrete, brick and block
 Package quantity: 1 piece
How to use
Install the drill bit into an SDS-compatible rotary hammer according to the tool manufacturer's instructions, ensuring the bit is fully seated and the locking mechanism engages. Select the rotary hammer mode suitable for hammer drilling and set the appropriate speed if the tool has variable control. Apply steady axial pressure while allowing the tool's hammer action to perform the cutting; avoid excessive force that can cause premature wear. Periodically withdraw the bit to clear dust and chips, especially when drilling deep holes, and let the bit and tool cool if drilling continuously.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling. Match the drill bit diameter to the intended anchor or fixation, and inspect the bit for wear or damage before use. For reinforced concrete, use controlled pressure and consider drilling pilot holes where applicable. Store the bit in a dry place to prevent corrosion and keep it separate from other tools to protect the carbide tip.
