Drill bit Dedra WB12015 — 1.2 cm diameter, 150 mm length, for concrete/brick/stone/aerated concrete

Dedra WB12015 drill bit, diameter 1.2 cm and length 150 mm, is designed for rotary and hammer drilling in masonry materials such as concrete, brick, natural stone and aerated concrete. The carbide-tipped head and optimized flute geometry improve penetration and chip evacuation, making the bit suitable for standard masonry tasks including anchor and dowel installation and repair works.

Advantages

The carbide tip delivers enhanced wear resistance and maintains cutting performance during repeated use in abrasive materials. The shank and flute design support efficient dust and chip removal, reducing overheating and jamming. With a 150 mm working length and a 1.2 cm diameter, the bit provides a balance between depth reach and stability for common fastening and repair operations in construction and renovation.

Suitable for

• Drilling holes for anchors and dowels in concrete and brick
• Creating passages through natural stone and masonry
• Repair and renovation tasks requiring medium-depth holes
• Working with aerated concrete for light structural fixings

Key specifications

• Diameter: 1.2 cm
• Overall length: 150 mm
• Tip material: carbide-tipped cutting head
• Intended use: rotary and hammer drilling in masonry
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Quantity: 1 piece

How to use

Secure the drill bit in a compatible rotary or hammer drill according to the tool manufacturer's instructions. Mark the drilling point, start at low speed to create a guide, then increase speed and apply steady pressure suitable for masonry drilling. Use hammer function when penetrating dense concrete or stone. Periodically withdraw the bit to clear debris and allow cooling. Replace the bit if wear degrades drilling performance or the carbide tip becomes damaged.

Usage recommendations

For best results, use appropriate drill speeds and the hammer function for dense materials; wear eye and respiratory protection when cutting masonry; ensure the drill chuck and bit shank are clean and properly secured before operation.
