Drill bit Dedra H1228, 200 mm, steel, for stone and concrete, 1 pc

Dedra H1228 drill bit, 200 mm in length, is a steel masonry bit designed for drilling stone and concrete. Supplied as a single piece, it is compatible with rotary and hammer drills that accept steel masonry bits and is intended for creating holes for anchors, dowels and through-fixings in masonry, blocks and reinforced concrete on construction and renovation tasks.

Advantages

This steel drill bit provides a durable cutting edge for drilling into hard mineral materials. The 200 mm length allows for deeper penetrations when installing anchors or running services through walls. As a single-piece tool it is straightforward to mount and use in standard rotary or hammer drill chucks that support masonry bits. The bit is specifically shaped for effective material removal in stone and concrete, reducing the need for multiple tool changes on typical building and repair jobs.

Suitable for

• Drilling holes for anchors and dowels in masonry and concrete
• Creating through-holes for wiring and pipes in block walls
• General drilling tasks in renovation and construction where stone or concrete must be penetrated

Key specifications

• Material: steel
• Length: 200 mm
• Intended materials: stone, concrete
• Quantity: 1 piece

How to use

Fit the Dedra H1228 drill bit securely into the drill chuck, ensuring correct seating and tightening. Select the appropriate drill mode—rotary or hammer—based on the drill and the hardness of the material. Start drilling at low speed to establish the hole, then increase speed and apply steady pressure while allowing the tool to do the work. Withdraw the bit occasionally to clear dust and debris and reduce heat build-up. When drilling deep holes, check alignment and depth periodically to ensure accurate placement for anchors or services.

Usage recommendations

Use appropriate personal protective equipment including eye and respiratory protection when drilling stone or concrete; employ water or dust extraction where practical to limit airborne silica dust. Match drill speed and hammer action to the material and the drill manufacturer's guidance to maximize bit life and maintain drilling performance.
