DeWalt drill bit SDS/EX2 15×260/200 mm for rotary hammers DT9575

DeWalt drill bit SDS/EX2 15×260/200 mm (DT9575) is a rotary hammer accessory developed for efficient drilling in concrete, brick and other masonry materials. The SDS shank ensures secure engagement with compatible rotary hammers and facilitates quick bit changes. With a 15 mm diameter and a 200 mm effective drilling length, this bit is intended for medium-depth holes while the 260 mm overall length provides additional reach for recessed or thicker structures.

Advantages

The SDS/EX2 geometry and hardened carbide tip deliver improved drilling speed and prolonged life when working with reinforced concrete and hard masonry. The robust shank design reduces slippage in the chuck and maintains alignment during hammering, while heat-treated construction increases resistance to wear. The 15 mm diameter balances hole size and structural integrity for common anchor and dowel installations.

Suitable for

• Drilling medium-depth holes in concrete for anchors and plugs
• Creating holes in brick and blockwork for mechanical fixings
• Preparation of mounting points for electrical boxes and conduit
• General masonry drilling tasks on construction and renovation sites

Key specifications

• Shank type: SDS/EX2 for rotary hammers
• Diameter: 15 mm
• Overall length: 260 mm
• Working/drilling length: 200 mm
• Tip material: carbide (hardened cutting tip)
• Intended materials: concrete, reinforced concrete, brick, blockwork

How to use

Install the bit into a compatible rotary hammer with an SDS/EX2 chuck, ensuring it locks securely. Select hammer drilling mode and start drilling at low speed to position the bit, then increase and maintain steady pressure while allowing the tool's hammer action to do the work. Periodically withdraw the bit to clear dust and debris and to prevent overheating. For reinforced concrete, advance with controlled motion to avoid binding against rebar.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask. For prolonged drilling sessions, use water suppression or a dust extraction system where permitted to reduce airborne silica dust. Match the 15 mm hole to the correct size of anchors or plugs and avoid excessive lateral forces that can damage the bit or the material.
