Drill Bit DeWalt DT9587 SDS-Plus 18 x 200/150 mm

DeWalt DT9587 SDS-Plus 18 x 200/150 mm is a rotary hammer drill bit designed for percussive drilling in concrete, masonry and other hard mineral materials. The bit has an 18 mm cutting diameter, an overall length of 200 mm and a working (effective) length of 150 mm. It is made for SDS-Plus chucks and features a carbide tip optimized for impact drilling, providing consistent hole quality and long tool life when used with compatible rotary hammers.

Advantages

The carbide tip maintains sharpness under repeated impact, helping to reduce wear during heavy-duty drilling. The SDS-Plus shank ensures secure seating and quick bit changes in rotary hammers that accept the SDS-Plus interface. With a balanced combination of diameter and working length, this drill bit offers effective penetration in standard masonry and concrete applications while remaining stable during percussive action.

Suitable for

• Drilling holes in concrete for anchor bolts and dowels
• Preparing masonry for through-fixings and service penetrations
• General construction and renovation tasks involving hammer drilling
• Work with SDS-Plus rotary hammers on reinforced and plain concrete

Key specifications

• Cutting diameter: 18 mm
• Overall length: 200 mm
• Working length (effective): 150 mm
• Shank type: SDS-Plus
• Tip material: carbide
• Application: hammer/percussive drilling in concrete and masonry

How to use

Fit the drill bit into an SDS-Plus compatible rotary hammer and ensure it is securely locked before starting. Mark the drilling point and use steady axial pressure, allowing the hammer action of the tool to perform the cutting; avoid excessive lateral force. For through-holes, periodically withdraw the bit to clear debris and improve cutting efficiency. Use appropriate drill speed and impact settings according to the rotary hammer manufacturer’s guidelines and the hardness of the material.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling. For prolonged use, remove dust periodically and check the cutting tip for wear; replace the bit when performance decreases to avoid oversized holes and increased load on the tool. Match the bit with an SDS-Plus rotary hammer suitable for an 18 mm diameter drill and select drill modes appropriate for the substrate being worked on.
