Drill bit Dedra WP0816 — 8 mm diameter, 100 mm working length, for concrete/brick/stone/aerated concrete, 1 pc

Carbide-tipped masonry drill bit Dedra WP0816 with an 8 mm diameter and 100 mm working length. This single-piece drill bit is designed for drilling into concrete, brick, natural stone and aerated concrete. The tip geometry and carbide cutting material provide durability and maintain drilling accuracy when used with hammer drills and rotary-percussion drills for installing anchors, dowels or passing conduits through masonry.

Advantages

The Dedra WP0816 offers a wear-resistant carbide tip that extends service life compared with standard high-speed steel bits. Its 100 mm working length allows reaching into walls and blocks while keeping the shank secure in the drill chuck. The bit is manufactured for stable centring and consistent hole diameter, which reduces chipping in brittle materials and helps ensure reliable fit of fixings.

Suitable for

• Drilling anchor and dowel holes in concrete and brick
• Creating passage holes for electrical conduits and pipes through masonry
• Installing fixtures in aerated concrete blocks and lightweight masonry
• General building and repair tasks requiring precise small-diameter holes

• Working length: 100 mm
• Tip material: Carbide-tipped cutting edge
• Compatible drilling modes: Hammer drilling and rotary-percussion
• Intended materials: Concrete, brick, natural stone, aerated concrete

How to use

Mark the drilling position and secure the workpiece or use appropriate support. Fit the 8 mm Dedra masonry bit into a suitable hammer drill chuck and tighten according to the drill manufacturer's instructions. Start drilling at low speed to establish the hole, then apply hammer function and steady pressure appropriate for the substrate. Withdraw the bit occasionally to clear dust and prevent overheating. After reaching the required depth, clean the hole before inserting anchors or ducts.

Usage recommendations

Use recommended personal protective equipment such as safety glasses and dust mask when drilling masonry. Match drill speed and hammer mode to the material: lower speed for dense natural stone, standard hammer setting for concrete and brick, and reduced percussion for aerated concrete to avoid cracking. Replace the bit when cutting performance or hole quality deteriorates.
