Drill bit Dedra WP1021, diameter 10 mm, working length 150 mm, for concrete/brick/stone/aerated concrete, 1 pc

Dedra WP1021 carbide-tipped drill bit, 10 mm diameter with a 150 mm working length, is made for drilling in concrete, brick, natural stone and aerated concrete. This single-piece bit is designed for use with hammer drills and rotary hammers to perform medium-duty construction tasks such as anchor and dowel installation, renovation works and masonry drilling while maintaining a straight drilling line.

Advantages

The carbide tip provides increased wear resistance and longer life when drilling abrasive masonry materials. The 150 mm working length enables deeper holes for anchors and through-fixings while the 10 mm diameter is compatible with common dowels and fasteners. The one-piece construction ensures stable centring and reduced breakage risk under standard hammering loads. Compatibility with both hammer drills and rotary hammers allows flexible use on site.

Suitable for

• Drilling holes for anchors and dowels in concrete and brick
• Installing fixtures in natural stone and aerated concrete
• Renovation and masonry work requiring medium-depth holes
• General-purpose drilling with hammer drills and rotary hammers

Key specifications

• Diameter: 10 mm
• Working length: 150 mm
• Tip material: carbide
• Suitable materials: concrete, brick, natural stone, aerated concrete
• Quantity: 1 piece

How to use

Select a drill chuck or holder compatible with a 10 mm shank and secure the bit firmly. Mark the drilling position, start drilling at low speed to create a guide, then increase to hammering mode for masonry as required. Apply steady axial pressure without forcing the bit; withdraw occasionally to clear dust when drilling deeper holes. After use, clean the bit of debris and store it dry to preserve the carbide tip.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and hearing protection, and follow the power tool manufacturer’s guidelines. For best results in reinforced concrete, drill slowly at the reinforcement, avoid excessive overheating, and replace the bit when cutting performance noticeably decreases.
