Tool holders are defined as a mechanical or structural system used to securely hold, align, and support tools, dies, or molds in manufacturing processes, ensuring stability, precision, and efficient force or energy transfer. Tool holders are mainly used in classical machining operation but the concept is frequently extended to other tool based industries such as cold working, hot working and plastic processing, where tool holders broadly describe systems that support and fix functional tooling components.
Tool holders are mechanical devices used to securely hold, position, and align tools or tool elements within a machine, ensuring precise force transmission, stability, and accuracy during manufacturing processes. In classical machining (e.g., CNC milling or drilling), tool holders act as the interface between the machine spindle and the cutting tool, providing rigid clamping, accurate alignment, and efficient transfer of motion and torque. This concept can be extended to other tool-based industries, where tool holders broadly describe systems that support and fix functional tooling components: Cold working (e.g., stamping, forming): Tool holders include systems such as die sets or punch holders that precisely position and secure forming tools under high mechanical loads. Plastics processing (e.g., injection molding, extrusion): Tool holders correspond to mold clamping and positioning systems that hold molds or inserts, ensuring alignment, pressure distribution, and thermal stability. Hot working (e.g., forging, die casting): Tool holders are structures that support dies or molds under extreme temperatures and stresses, maintaining consistent positioning and compensating for thermal expansion.
The newly developed, patent pending, BÖHLER E185 AMPO is an AM powder, fulfilling the highest demands from various industries, ranging from motorsport to engineering components and any kind of prototype applications. This low alloyed steel with easy printability and the possibility for surface treatments (e.g. case hardening or nitriding) was developed especially for the demands of the 3D printing industry. The material shows an excellent combination of strength and toughness.

Read MoreBÖHLER M238 is a prehardened, non-corrosion-resistant plastic mould steel with good machinability. The addition of Ni guarantees uniform strength across the entire cross-section, even with large dimensions (up to 600 mm).
Read MoreBÖHLER M789 AMPO is a newly developed maraging steel, which combines the mechanical properties of 1.2709 with the corrosion resistance of 17-4PH. This patent bending grade can easily printed without any preheating and achieves a hardness of about 52 HRC with a very easy heat treatment. Furthermore, this material shows an excellent polishability, which makes it the ideal choice for inserts with conformal cooling in plastic injection molding and in any other application where a high hardness and corrosion resistance is of need.
Read MoreBÖHLER W302 ISOBLOC is a 5% chromium steel and corresponds to material number 1.2344 (X40CrMoV5-1). Produced via the electroslag remelting process (ESR), this tool steel has very high hot toughness as well as very high hot hardness and a very good resistance against heat-checkings. The combination of these properties makes it a top performer in closed- and open-die forging as well as in high- and low-pressure die casting. In addition, this material has very good polishability and is therefore also often used as a molding material for plastic injection molds.
Read MoreBÖHLER W302 ISODISC is a 5% chromium steel and corresponds to material number 1.2344 (X40CrMoV5-1). This common tool steel has good hot toughness as well as a high hot hardness and a high resistance against heat-checkings. The combination of these properties makes it a standard choice in extrusion, forging and low-pressure die casting. This material is also available as W302 ISOBLOC which is a remelted grade with improved cleanliness, homogeneity and toughness.
