Drill bit Dedra WP0621 — 6 mm diameter, 150 mm working length, for concrete/brick/stone

Dedra WP0621 drill bit — 6 mm diameter with 150 mm working length — is designed for drilling into concrete, brick, stone and aerated concrete. This single-piece masonry bit is suitable for both rotary and hammer drilling modes and provides a straight, consistent hole for installing anchors, electrical boxes, plumbing routes and other construction or renovation tasks that require precise masonry perforations.

Advantages

The Dedra WP0621 combines a compact 6 mm diameter with an extended 150 mm working length to reach deeper anchoring points while keeping control and stability. Its one-piece design reduces the risk of breakage at joints and improves durability under hammer action. The tip geometry and flute design are optimized for efficient dust removal and consistent drilling speed in hard masonry materials.

Suitable for

• Drilling holes for wall anchors and screws in concrete and brick
• Creating openings for electrical boxes and conduit routes
• Plumbing and HVAC installations requiring masonry penetrations
• General renovation and construction tasks that need precise masonry holes

Key specifications

• Diameter: 6 mm
• Working length: 150 mm
• Intended materials: concrete, brick, stone, aerated concrete
• Design: single-piece masonry drill bit suitable for rotary and hammer drilling
• Pack quantity: 1 piece

How to use

Mark the drilling position and select a drill supporting hammer mode if required for the material. Secure the workpiece or ensure the drilling surface is stable. Fit the Dedra WP0621 into the drill chuck and tighten according to the drill manufacturer's instructions. Start drilling at low speed to establish the position, then increase speed and engage hammer action for concrete or brick as needed. Withdraw the bit occasionally to clear debris and avoid overheating. After reaching the required depth, remove the bit and clean the hole before inserting anchors or fixtures.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask and hearing protection) and a vacuum or dust extraction system when drilling masonry. For best results in reinforced concrete or very hard stone, use controlled pressure and short drilling intervals to prevent bit wear. Match anchor and screw sizes to a 6 mm hole to ensure correct fit and load-bearing performance.
