Drill bit DeWalt DT9588 SDS-Plus 18 x 250/200 mm

DeWalt DT9588 SDS-Plus 18 x 250/200 mm is a rotary hammer drill bit designed for drilling holes in concrete, masonry and other mineral-based substrates. The bit has an 18 mm diameter, a total length of 250 mm and a working (effective) length of 200 mm, and is compatible with SDS-Plus hammer drills. A carbide tip provides improved wear resistance and reliable percussion drilling performance, while the flute geometry aids chip removal to maintain drilling speed and reduce bit binding.

Advantages

The carbide tip increases durability and extends service life when drilling in abrasive materials. SDS-Plus shank design ensures secure, slip-free connection with compatible rotary hammer chucks and allows quick bit changes. Optimised flute geometry improves dust and chip evacuation, helping to maintain steady drilling progress and reduce heat build-up. The combination of a 200 mm working length and compact overall length makes the bit suitable for both confined-space and general on-site tasks.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Making holes in brick and block masonry
• Installing electrical boxes and conduits in walls
• General construction and renovation drilling tasks

Key specifications

• Shank type: SDS-Plus compatible
• Diameter: 18 mm
• Total length: 250 mm
• Working (effective) length: 200 mm
• Tip material: carbide
• Intended materials: concrete, masonry and similar mineral substrates

How to use

Insert the SDS-Plus shank into the hammer drill chuck until it locks, then set the tool to hammer drilling mode. Align the carbide tip with the marked drilling position and apply steady axial pressure while allowing the drill to perform the percussion action. Use moderate feed force to avoid premature wear; remove the bit periodically to clear dust and debris from the hole. When drilling deep holes, withdraw the bit intermittently to improve chip evacuation and cooling.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection and a dust mask when drilling concrete or masonry. Match drill speed and feed pressure to the substrate hardness; for prolonged or heavy-duty use, consider using a drill with adequate power and hammer energy to preserve bit life and performance.
