Drill bit Dedra WPQ1680, diameter 1.6 cm, for concrete/brick/stone/aerated concrete, 135° point, 1 pc

Dedra WPQ1680 drill bit with a 1.6 cm diameter and a 135° point is made for drilling masonry materials such as concrete, brick, natural stone and aerated concrete. Supplied as a single piece, this masonry drill is suitable for use with rotary drills and with hammer action where the tool and chuck are compatible. The geometry and cutting tip are designed to provide accurate hole starting and consistent performance when installing anchors, fixing fixtures or carrying out general construction drilling tasks.

Advantages

The 135° point angle improves centring and reduces walking on smooth surfaces, which helps achieve precise hole placement. The 1.6 cm diameter offers a balance between hole size and structural strength for common anchoring and fixing applications. Supplied as a single solid bit, it is easy to store and replace in a toolkit. The drill bit is specified for hard masonry materials, offering resistance to chipping at the cutting edge when used with appropriate drilling technique and speed.

Suitable for

• Creating holes for anchors and wall plugs in concrete and brick
• Drilling mounting points for fixtures and brackets in stone and masonry
• Preparing openings in aerated concrete for light- to medium-duty fixings
• General construction and renovation drilling where a single 1.6 cm masonry hole is required

Key specifications

• Diameter: 1.6 cm
• Point angle: 135°
• Compatible materials: concrete, brick, natural stone, aerated concrete
• Quantity in pack: 1 piece

How to use

Mark the drilling position and secure the work area. Select a drill with appropriate power and, if available, a hammer function suitable for masonry. Fit the WPQ1680 bit into the chuck and tighten securely. Start drilling at low speed to establish the hole, then increase speed or enable hammer action as required for the material. Apply steady axial pressure without forcing the bit; withdraw periodically to clear dust and allow the bit to cool. After reaching the required depth, clean the hole before inserting anchors or fixings.

Usage recommendations

Use personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry. Match drill speed and hammer mode to material hardness, and avoid excessive lateral force to prolong bit life. For repeated or heavy-duty work, consider using dedicated SDS or carbide-tipped masonry bits matched to your drill type.
