A disc tool replacement machine comprising:

• a controller configured to determine that a tool holder of an automated machine is in a replacement area associated with the disc tool replacement machine, the automated machine working with disc tools;
• a fastening tool configured to unfasten a fixing member of the tool holder by providing an unfastening force to the fixing member, wherein the fixing member fixes a first disc tool to a backing plate of the tool holder using a through hole at a centre of the first disc tool;
• a replacement system configured to remove the first disc tool from the tool holder after said unfastening and to provide a new disc tool to the tool holder,
• wherein the fastening tool is further configured to fasten, after the new disc tool has been provided to the tool holder, the fixing member of the tool holder by applying a fastening force to the fixing member, thus fixing the new disc tool to the backing plate of the tool holder through a new through hole associated with the new disc tool;
• at least one gripper, the at least one gripper having a lower end that is proximal to the fastening tool and having an upper end that is distal to the fastening tool, the at least one gripper configured to grip the tool holder and to position the tool holder in the replacement area such that the first disc tool, that is fixed to the tool holder, is located at the lower end of the at least one gripper, proximate the fastening tool, wherein the first disc tool detaches from the tool holder and remains on top of the fastening tool after said unfastening, wherein the replacement system is configured to grip the first disc tool and remove the first disc tool from the fastening tool, and is configured to provide the new disc tool on top of the fastening tool, and wherein the fastening tool is configured to rise towards the tool holder to bring the new disc tool into contact with the backing plate;
• and
• a first storage area configured to store used disc tools and a second storage area configured to store unused disc tools, wherein the replacement system is configured to grip the first disc tool with a replacement member when removing the first disc tool from the top of the fastening tool and move the first disc tool to the first storage area, the replacement system being configured to grip the new disc tool from the second storage area when removing the new disc tool from the second storage area and place the new disc tool on top of the fastening tool before fastening the new disc tool to the tool holder.
