Drill bit Dedra WPQ0826, 8 mm diameter, for concrete, brick, stone, aerated concrete, 135° point, 1 pc

Dedra WPQ0826 is an 8 mm diameter drill bit engineered for drilling into concrete, brick, natural stone and aerated concrete. The bit has a 135° point angle that supports controlled penetration and helps reduce chipping and cracking when starting holes in masonry materials. Supplied as a single piece, this drill bit is intended for use with hammer drills and rotary-percussion tools in construction, installation and repair tasks where reliable masonry drilling is required.

Advantages

The 135° point provides a balanced cutting geometry that improves centring and reduces walking on hard surfaces. Designed for use on masonry materials, the bit’s geometry and heat-resistant construction support consistent drilling performance and longer service life under typical jobsite conditions. Its 8 mm diameter offers a common size for anchors, dowels and through-holes, allowing straightforward compatibility with standard fixing systems and fasteners.

Suitable for

• Drilling holes for wall plugs and anchors in concrete
• Creating holes in brickwork for electrical and plumbing installations
• Making openings in natural stone for fixtures and fittings
• Drilling through aerated concrete blocks for light construction work

Key specifications

• Diameter: 8 mm
• Point angle: 135°
• Suitable materials: concrete, brick, natural stone, aerated concrete
• Quantity: 1 piece
• Intended tool type: hammer drill / rotary-percussion drill

How to use

Secure the drill bit in the chuck of a compatible hammer drill or rotary-percussion tool and tighten according to the tool manufacturer’s instructions. Mark the drilling location and begin at low speed to position the bit, then apply steady pressure and increase speed appropriate for the material. For deep holes or dense materials, periodically withdraw the bit to clear dust and debris and allow cooling. Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry.

Usage recommendations

Use the Dedra WPQ0826 with a hammer function enabled on the drill for concrete and stone; switch to rotary-only mode if the material is brittle or when precision without percussive action is required. Match drill diameter to the recommended size for plugs or anchors, and avoid excessive force to prevent bit fracture and material damage.
