Drill bit Dedra WP0511 — 5 mm diameter, 50 mm working length, for concrete/brick/stone/aerated concrete, 1 pc

Single Dedra WP0511 masonry drill bit, 5 mm diameter with a 50 mm working length, designed for drilling in concrete, brick, natural stone and aerated concrete. The bit is intended for use with hammer and rotary drills for construction, renovation and installation tasks where accurate 5 mm holes are required for anchors, dowels and through-holes.

Advantages

How to use

Select a hammer or rotary drill compatible with masonry bits and set the appropriate drilling mode for the substrate. Mark the drilling point and use a center punch if needed to prevent bit walking. Start drilling at low speed to establish the hole, then apply steady pressure and use hammer action for dense concrete or stone. Periodically withdraw the bit to clear dust from the hole and avoid excessive heat buildup. Maintain proper personal protective equipment, such as safety glasses, ear protection and dust mask.

Usage recommendations

Use the Dedra WP0511 for precise 5 mm holes; for deeper or larger holes choose a bit with a longer working length or larger diameter. When drilling into reinforced concrete, check for rebar and reduce applied force if encountering metal. Replace the bit when cutting performance decreases or tip damage is visible to ensure consistent hole quality.
