Drill bit Dedra WPQ1631 — diameter 1.6 cm, 135° point, for concrete and masonry, 1 pc

Dedra WPQ1631 drill bit with a 1.6 cm diameter and a 135° point angle is designed for drilling precise holes in concrete, brick, stone and aerated concrete. This single-piece carbide-tipped geometry is intended for use with rotary and hammer drills where controlled penetration and resistance to wear are required. The bit's shape and tip angle support accurate centering and reduced walking on hard and granular surfaces.

Advantages

The 135° point provides improved centering and a controlled cutting action that reduces chipping in brittle masonry materials. Carbide-tipped construction increases wear resistance and extends useful life compared to standard steel bits. The 1.6 cm diameter offers a specific bore size for structural anchors, anchor bolts and through-holes in common masonry applications.

Suitable for

• Drilling holes for anchors and fixings in concrete and brick
• Creating passages for pipes or cables in masonry walls
• Preparing openings for plugs and anchor bolts
• Work on aerated concrete blocks and natural stone

Key specifications

• Diameter: 1.6 cm
• Tip angle: 135°
• Suitable materials: concrete, brick, stone, aerated concrete
• Quantity: 1 piece
• Tip material: carbide-tipped geometry for enhanced wear resistance

How to use

Mount the Dedra WPQ1631 drill bit in a compatible rotary or hammer drill according to the drill manufacturer's instructions. Select a drill speed and hammer action appropriate for masonry: start at a moderate speed to establish the hole, then apply consistent pressure without forcing the bit. For deeper holes, periodically withdraw the bit to clear dust and debris to maintain cutting efficiency. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling.

Usage recommendations

For best results when drilling concrete and brick, use the hammer function on rotary hammer drills and match drill speed to material hardness. When installing anchors, verify hole diameter and depth against anchor manufacturer specifications. Replace the bit when wear reduces cutting performance to avoid excessive load on the drill and suboptimal hole quality.
