Where Is a Chisel Tool Used?
Chisel tools are versatile, general-purpose tools that combine cutting action with controlled fracturing in medium-hard and veined materials. The sharpened edge penetrates reinforced concrete and hard rock easily.
- Primary demolition
- Secondary demolition
- Trenching
- Recycling
- Scaling
- Primary breaking
- Boom mounted applications
According to the material table in our manual, it is recommended for reinforced concrete slabs, walls, columns and foundations, heavily fractured rock, asphalt and frozen ground.
The dust grooves guide dust and fine particles away from the breaking zone. Visibility and precision improve, tool wear and heat build-up drop, and the tool keeps its performance longer.
Correct Use: Three Rules
- Work perpendicular. Keep the breaker at a right angle to the surface and avoid side loads. Angled pushing wears the bushings and moves the piston off the tool axis.
- Do not pry. Rocking the tool like a lever before it is fully seated, or rotating the breaker while the tool is embedded, is the most common cause of tool breakage.
- Do not twist the chisel. A chisel tends to rotate along its path. This twisting wears the retaining pin slots and makes the tool break at the slot.
Breakage caused by ignoring these rules is not covered by the warranty. See our tool selection guide, the tool use section and the Tool User Manual and Warranty Terms.

Frequently Asked Questions
Q: What are the dimensions of the MTB MT30 dust grooved chisel tool?
A: The MTB MT30 dust grooved chisel tool is made for the MTB MT30 hydraulic breaker: diameter 70 mm, overall length 680 mm, weight 20 kg. Just state your breaker brand and model when you order.
Q: Will another tool with the same diameter and length fit my MTB MT30?
A: Not always. The position and shape of the retaining pin slot change with brand and model; a tool with the same diameter and length may not fit. This tool is made to the slot dimensions of the MTB MT30.
Q: What is the MTB MT30 dust grooved chisel tool used for?
A: The MTB MT30 dust grooved chisel tool is mainly used for: primary demolition, secondary demolition, trenching, recycling, scaling, primary breaking, boom mounted applications. According to the material table in our manual, it is recommended for reinforced concrete slabs, walls, columns and foundations, heavily fractured rock, asphalt and frozen ground.
Q: What do the dust grooves on the MTB MT30 dust grooved chisel tool do?
A: The dust grooves guide dust and fine particles away from the breaking zone. Visibility and precision improve, tool wear and heat build-up drop, and the tool keeps its performance longer.
Q: Which other tool types are available for the MTB MT30?
A: We make 14 different tools for the MTB MT30: moil point tools, chisel tools, pyramid tools, blunt tools, with dust grooved and hard rock options. You can reach all of them from the Other Tool Types table on this page.
Q: How long is the delivery time for the MTB MT30 dust grooved chisel tool?
A: If the MTB MT30 dust grooved chisel tool is in stock, it ships quickly. If not, it is made in 5 working days; transport time is added depending on the shipping method.
Q: Is the MTB MT30 dust grooved chisel tool covered by warranty?
A: Like all HKM breaker tools, the MTB MT30 dust grooved chisel tool is warranted against manufacturing defects only. The fracture surface is examined; if the fracture started from a flaw inside the material, the tool is covered. Breakage from prying, blank firing, rotating the embedded tool or working with worn bushings is not covered.
Q: What shortens the life of the MTB MT30 dust grooved chisel tool the most?
A: Prying before the tool is fully seated, blank firing, striking one spot for too long, insufficient or wrong grease, and working with worn bushings. On a chisel, twisting also wears the retaining pin slots.
Q: What else should I check when I change the tool on my MTB MT30?
A: Compare the inner diameters of the lower and upper bushings and the thrust bushing surface with the tolerances in your breaker's service manual. Worn bushings move the tool and piston off axis. The MTB MT30 bushings are listed in the Spare Parts section on this page.
Q: What other names is the MTB MT30 dust grooved chisel tool known by?
A: It is also called “wedge”, “wedge tool”, “flat chisel”, “dust chisel”, “DEG chisel”. Breaker tools in general are also known as breaker chisels, working tools or hammer tools.
