Drill bit Dedra WXQ1457 — diameter 1.4 cm, for concrete, brick, stone, aerated concrete, 135° point

Dedra WXQ1457 is a single masonry drill bit with a 1.4 cm diameter, designed for drilling into concrete, brick, natural stone and aerated concrete. The bit features a 135° point angle that improves centering on hard surfaces and reduces walking at the start of the hole. Supplied as one piece, this drill bit is intended for repair, installation and construction tasks where reliable penetrating performance into masonry materials is required.

Advantages

The 135° point angle provides improved accuracy and quicker bite when starting holes in hard masonry. Its 1.4 cm diameter offers a balance between clearance and holding capacity for anchor bolts and dowels commonly used in construction. The geometry and cutting edges are optimized for clean material removal in concrete, brick and stone, while performance on aerated concrete preserves hole integrity. Supplied as a single unit, the bit is convenient to keep as a spare or to use for one-off installation jobs.

Suitable for

• Drilling holes for anchors and plugs in concrete and brick
• Creating passageways for fasteners in natural stone and masonry
• Installing fixtures and fittings in aerated concrete panels
• Repair and light construction tasks requiring a 14 mm hole

Key specifications

• Diameter: 1.4 cm (14 mm)
• Point angle: 135° for improved centering
• Material compatibility: concrete, brick, natural stone, aerated concrete
• Pack content: single drill bit

How to use

Select a drill speed and hammer function suited for masonry materials and secure the bit in a compatible rotary hammer or hammer drill. Mark the drilling position and, if needed, create a small pilot dimple. Start drilling at low speed to ensure the 135° point locates the center, then increase speed and use hammer action for dense concrete. Apply steady pressure without forcing; withdraw occasionally to clear debris and prevent overheating. Match hole depth and diameter to the anchor or plug being installed.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry. For reinforced concrete, confirm rebar position before drilling and avoid prolonged contact with reinforcing steel. Store the drill bit in a dry place and inspect the cutting edges before use; replace the bit if signs of excessive wear or damage appear.
