Drill Bit DeWalt SDS-Plus DT9539 10x110/50 mm, hammer drill masonry bit

SDS-Plus drill bit DeWalt DT9539 with a 10 mm diameter, 110 mm total length and 50 mm working length is a masonry/impact bit designed for hammer drills. The bit is intended for drilling into concrete, brick and natural stone. It uses an SDS-Plus shank for fast and secure fitting to compatible rotary hammers and provides stable rotation during impact drilling. This tool is suitable for construction, installation and renovation tasks where reliable masonry drilling is required.

Advantages

The drill bit combines a carbide tip geometry optimized for percussive drilling with a hardened steel body to resist wear and deformation. The SDS-Plus system ensures quick insertion and removal while maintaining axial stability under load. Its 10 mm working diameter and 50 mm effective drilling depth make it suitable for anchor and dowel installation as well as through-holes in masonry. The compact total length of 110 mm improves maneuverability in confined spaces.

Suitable for

• Drilling holes for anchors, dowels and screws in concrete and brick
• Installation of fixtures, conduits and cable routes in masonry walls
• General renovation and construction drilling tasks requiring percussive action

Key specifications

• Diameter: 10 mm
• Total length: 110 mm
• Working (effective) length: 50 mm
• Shank type: SDS-Plus
• Application: masonry/impact drilling into concrete, brick and stone
• Tip material: tungsten carbide tip for improved wear resistance

How to use

Select an SDS-Plus compatible hammer drill and secure the bit by inserting the shank into the tool’s chuck until it locks. Set the drill to hammer or rotary-hammer mode depending on the machine. Mark the drilling position, start at low speed to establish the hole, then increase speed and apply steady pressure without forcing the bit. Periodically retract the bit to clear debris and prevent overheating when drilling deep holes. After completing the hole, remove the bit by pulling it out of the chuck while the tool is switched off.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and, when drilling reinforced concrete, use a drill setting suitable for mixed materials. For longer service life, avoid excessive lateral force and allow the carbide tip to cool by intermittent drilling; replace the bit when wear affects drilling performance or accuracy.
