Drill bit Dedra WPQ0621 — 6 mm, for concrete/brick/stone/aerated concrete, 135° point

Dedra WPQ0621 is a single 6 mm masonry drill bit designed for drilling in concrete, brick, stone and aerated concrete. The bit has a 135° point angle optimized for percussion drilling with hammer drills and rotary hammers, providing efficient penetration and reliable chip evacuation for anchor holes, through-holes and dowel installation.

Advantages

The 135° point reduces wandering at the start of drilling and improves centring on hard surfaces. A 6 mm diameter gives a common size for standard wall plugs and fasteners, while the masonry tip geometry and fluting are intended to enhance dust removal during hammer action. The product is supplied as a single piece, making it suitable for occasional replacement or for carrying a spare bit in a toolbox.

Suitable for

• Drilling anchor holes for wall plugs and dowels in concrete and masonry
• Creating through-holes for cable or pipe passage in brick and stone
• Light to medium-duty installation work with hammer drills or rotary hammers

Key specifications

• Diameter: 6 mm
• Point angle: 135°
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Intended drill type: percussion (hammer drill) and rotary hammer
• Quantity: 1 piece

How to use

Select a hammer drill or rotary hammer appropriate for masonry work and fit the Dedra WPQ0621 6 mm bit into the drill chuck or SDS adapter as applicable. Mark the drilling position and start at low speed to establish the hole, then apply steady pressure while switching to percussion mode for concrete or dense masonry. Periodically withdraw the bit to clear dust and allow cooling when drilling deep holes. Use appropriate wall plugs sized for a 6 mm hole when installing anchors.

Usage recommendations

Wear suitable eye and hearing protection and a dust mask when drilling. Use a drill with the correct power and hammer action for the material: lower impact settings for aerated concrete and higher settings for dense concrete. For repetitive or large-diameter drilling, consider specialist bits or a drill with dust extraction to prolong bit life and maintain a clean workspace.
