## Long description

DeWalt SDS+ masonry drill bit 4 mm H1-DT9503 is a slim, purpose-built bit for drilling small-diameter holes in concrete and other masonry materials. Designed for use with SDS+ rotary hammer drills, this 4 mm drill bit enables accurate, repeatable drilling required for anchors, dowels and light fastenings. The bit geometry and carbide tip are optimised to maintain drilling stability and edge retention during frequent use on hard substrates.
Advantages
The drill bit delivers precise hole positioning and consistent diameter control, reducing the need for rework when installing anchors or fixings. Its SDS+ shank ensures secure retention and quick bit changes in compatible rotary hammers. The carbide tip offers improved wear resistance compared with standard steel bits, supporting longer service life when used appropriately on masonry.
Suitable for
Drilling 4 mm holes in concrete for anchors and dowels
Light fixing work in brick, block and other masonry materials
Professional and DIY tasks requiring precise small-diameter holes
Key specifications
Drill diameter: 4 mm
Shank type: SDS+ compatible
Suitable materials: concrete, brick, block and similar masonry
Tip material: carbide cutting tip for masonry
Intended use: rotary hammer drilling (hammer mode)
How to use
Install the bit in the SDS+ chuck of a rotary hammer drill until it locks. Select hammer drill mode and set an appropriate drilling speed for small-diameter masonry holes. Apply steady forward pressure without forcing the bit; allow the hammering action to remove material. Periodically withdraw the bit to clear dust from the hole and avoid overheating. Use correct personal protective equipment, including eye and ear protection and a dust mask, when drilling concrete or masonry.
Usage recommendations
For best results, start with a pilot position marked on the surface and use consistent pressure to prevent bit wandering. Match the hole depth to the length of the anchor or dowel and use a vacuum or compressed air to clear dust before inserting fixings.
