Are you looking for an extremely robust, reliable and highly effective tool for removing the toughest construction materials? The HEX 75x400mm Demolition Hammer Chisel (Product Code: G40053) is the ultimate choice for anyone who needs maximum performance on the toughest construction and demolition projects. With its optimal blade width of 75mm and length of 400mm, this flat chisel enables extremely fast, precise and comfortable material removal with minimal effort.
This professional wide chisel is an indispensable tool in the Chisels and Drills category, suitable for both experienced builders and craftsmen as well as demanding DIYers. Thanks to the standard 30 mm hexagonal (HEX) shank, the chisel is fully compatible with most heavy-duty electric demolition hammers on the market, ensuring smooth, uninterrupted work.
Why Choose Professional HEX Wide Chisel G40053?
In demanding demolition work, two factors are crucial: the speed of the work and the durability of the tool used. The wide chisel measuring 75x400 mm offers the perfect ratio between the coverage of the working surface and the transmission of the machine's impact power. The wide blade (75 mm) enables significantly faster peeling and removal of larger pieces of material compared to classic narrow chisels, while the length of 400 mm ensures excellent reach and greater user safety at work.
Its sophisticated design with a 30 mm hexagonal shank (HEX-30 shank) ensures optimal energy transfer from the demolition hammer directly to the work surface. This prevents unnecessary loss of impact power and reduces the risk of the tool slipping in the machine's chuck.

Main Benefits of Using the G40053 Wide Chisel
1. Exceptional Material Removal Efficiency
The 75 mm blade width is specially optimized for removing old ceramic tiles, hard plasters, screeds, adhesives and for cleaning concrete surfaces. Forget about time-consuming and tiring work with narrow chisels - with this wide chisel you will clean the surface in significantly less time and with less effort.
2. Perfect Power Transfer with Standard HEX 30mm Mount
The 30 mm hexagonal shank (HEX) ensures maximum tool stability during operation. This clamping system effectively prevents the chisel from rotating in the machine head, which not only extends the life of the clamping mechanism of your demolition hammer, but also ensures that all impact energy is transferred directly to the workpiece.
3. Versatile Use on Every Construction Site
This chisel is indispensable for a wide range of construction jobs. You can use it to demolish partitions, punch holes in brick and concrete, remove asphalt or effectively clean hardened concrete residue from formwork. It is a versatile accessory that should not be missing from any toolbox.
Use and Maintenance for Maximum Lifespan
To ensure an exceptionally long chisel life and at the same time protect your demolition hammer, we recommend following these simple instructions:
Before each use, clean the chuck shank (HEX 30mm) and apply a thin layer of special chisel grease. Never use the chisel as a lever (pry bar) while working, as this can cause overheating or damage to the material. Let the impact power of your machine do most of the work.

Answers to frequently asked questions

What materials is this chisel suitable for?

The HEX wide chisel is designed for removing harder materials such as concrete, stone, masonry and mortar where high impact power is required.

Is this chisel compatible with all demolition hammers?

It is important that the tool supports the HEX clamping system and has the appropriate power to work with wide chisels. Always check the compatibility with your hammer before purchasing.
