Description
Chisels turn a rotary hammer into a demolition and chasing tool. A chisel is fitted in the SDS chuck and used in impact mode, with the machine’s hammer action driving the blade into concrete, masonry or stone. The right chisel shape for the task matters as much as the machine.
Heller chisels are made from low-wear tool steel with a special hardening process, which gives them a long service life. Their rugged design also allows the user to regrind the chisel. The range is made for both SDS-plus and SDS-max machines, in several versions, so one family of tools covers light chasing work through to heavy demolition.
Chisels are available as individual tools and in sets that combine the most common shapes. Sizes and variants vary by chisel type and shank, so selection starts with the task and the machine.
Key Features and Benefits
Shapes for each task
Heller makes chisels for the common tasks in concrete and stone work, from breaking and removal to precise chasing. The chisel types section below sets out the main shapes and what they are for.
Hardened tool steel
Low-wear tool steel and a special hardening process give the chisels a long service life, and the rugged construction allows them to be reground rather than replaced.
SDS-plus and SDS-max shanks
SDS-plus chisels are for lighter rotary hammers and finer work, and SDS-max chisels are for heavier hammers and tougher demolition tasks. Premium versions are designed with blade profiles that reduce wear and vibration.
Sets for mixed work
Sets bring the main chisel shapes together in one pack, which suits teams that switch between breaking, chasing and finishing.
Applications and Use Cases
Heller chisels are used for:
- demolition and breaking of concrete, masonry and stone
- chasing and slotting for cables, ducting and services
- removing and cleaning joints in masonry, and grouting
- refurbishing masonry and joints
- creating through-holes
- removing tiles
Not every chisel type suits every task or material, and SDS-plus and SDS-max chisels cannot be interchanged between machines. Blade design, length, width and other features vary by chisel type and version.

When selecting chisels, consider:

- the task: breaking, chasing, joints or tiles
- the base material
- the working width and length the job requires
- whether a set or single chisels suit the work

Frequently Asked Questions
What is the difference between SDS-plus and SDS-max chisels?
The shank. SDS-plus chisels fit SDS-plus machines and SDS-max chisels fit SDS-max machines. They are not interchangeable. SDS-max chisels are made for heavier hammers and tougher demolition tasks.
Which chisel should I use for chasing and which for demolition?
Chasing for cables and ducting calls for pointed, ducting, grooving or wing chisels. Breaking and demolition call for pointed or flat chisels, and spade chisels for removing larger amounts of material.
Can Heller chisels be reground?
Yes. Heller chisels are designed with a rugged construction that allows the user to regrind them.
Are chisels used in impact mode?
Yes. Chisels fit machines with an SDS chuck and are used in impact mode.
