Drill bit Dedra WP0516 — 5 mm diameter, 100 mm working length, for concrete/brick/stone/aerated concrete, 1 pc

Dedra WP0516 is a 5 mm diameter percussion drill bit with a 100 mm working length, designed for use in masonry and construction. Manufactured for use with hammer and rotary-percussion drills, this single-piece bit is intended to create precise, small-diameter holes in concrete, brick, natural stone and aerated concrete. The straightforward design and conventional dimensions make it suitable for installers, builders and DIY users who require reliable performance when drilling into hard materials.

Advantages

The Dedra WP0516 drill bit combines a narrow 5 mm diameter with a 100 mm working length to reach recessed points while maintaining accuracy. Its construction is optimized for percussion action, ensuring effective chip removal and stable drilling progress in masonry materials. Supplied as a single piece, it is compatible with common hammer and rotary-percussion drills and provides consistent hole size for anchors, dowels and pass-throughs in structural and finishing work.

Suitable for

• Drilling holes for wall plugs and small anchors in concrete and brick
• Installing fixtures and fittings in natural stone and aerated concrete
• Light construction and renovation tasks requiring precise small-diameter holes
• DIY projects where compact, controlled masonry drilling is needed

Key specifications

• Diameter: 5 mm
• Working length: 100 mm
• Intended materials: concrete, brick, natural stone, aerated concrete
• Tool compatibility: hammer drills and rotary-percussion drills
• Quantity: 1 piece

How to use

Select a hammer or rotary-percussion drill with a compatible chuck and secure the Dedra WP0516 bit firmly. Mark the drilling point, start at low speed to position the bit, then increase percussion action and speed appropriate to the substrate. Apply steady, moderate pressure and allow the bit to progress without forcing; withdraw periodically to clear dust if necessary. For through-holes or fixing installation, confirm hole depth and clean the hole before inserting plugs or anchors.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and hearing protection, when drilling masonry. Match drill speed and percussion force to the material: lower speeds for harder stone, medium speeds for concrete and brick, and controlled action for aerated concrete to avoid overbreak. Replace the bit when wear degrades hole accuracy or drilling efficiency.
