Drill bit DeWalt DT9590 for rotary hammer, Ø 18 mm, length 450 mm, 1 pc

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

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.
