The right tool clamping technology for every kind of machining operation: HAIMER Tool Holders

During machining, specific demands for tool holding are laid down by each industry and application. The range varies from high-speed cutting to heavy roughing.
With the HAIMER tool holders, HAIMER offers the right solution and tool clamping technology for all specific requirements. Therefore, each year we invest approximately 10 percent of our turnover in research and development.
Our primary interest is to offer our customers sustainable solutions which enable a competitive advantage. This way, you can always maintain your competitive advantage in machining.
Steep taper DIN ISO 7388-1 SK30/SK40/SK50 (formerly DIN 69871)

The traditional interface for milling spindles DIN ISO 7388-1 (formerly 69871) distinguishes itself through its extremely robust design. Its field of application ranges from fine machining to heavy duty roughing. The tool holder is pulled in the milling spindle with the help of an additional pull stud. The centering takes place via the taper contact. Therefore, the DIN ISO 7388-1 (formerly 69871) interface is primarily suitable for applications with a spindle speed of up to 12,000 rpm.
Steep taper ASME B5.50 CAT40/CAT50

The traditional interface for milling spindles ASME B5.50 distinguishes itself through its extremely robust design. Its field of application ranges from fine machining to heavy duty roughing. The tool holder is pulled in the milling spindle with the help of an additional pull stud. The centering takes place via the taper contact. Therefore, the ASME B5.50 steep taper interface is primarily suitable for applications with a spindle speed of up to 25,000 rpm.
Steep taper JIS (MAS 403) BT30/BT40/BT50

The spindle interface JIS B 6339-2 as the traditional interface for milling spindles distinguishes itself through it robust design. Its field of application ranges from fine machining to heavy duty roughing. The tool holder is pulled in the milling spindle with the help of an additional pull stud. The centering takes place via the taper contact. Therefore, the JIS B 6339-2 interface is primarily suitable for applications with a spindle speed of up to 12,000 rpm.
Hollow taper shank DIN 69893 HSK-A, HSK-E, HSK-F

The interface DIN 69893 has become the new standard for machining centres. The holder is clamped via its taper with flange contact surface. By doing so, a highly accurate centring and fixed axial position of the holder in the spindle is granted with a high repetitive accuracy when exchanging the tools. In the DIN 69893-1 HSK-A interface design an additional torque transmission takes place at the taper shank with drive keys. DIN 69893 HSK-A/HSK-E/HSK-F is mainly used in high-speed machining.
ISO 26623 HAIMER PSC 63

The ISO 26623 spindle interface is an innovative tooling system with maximum precision and particularly widespread in multi-task machines (turn-mill centres). The torque transmission and centring takes place via the polygon-shaped taper with flange surface contact. As a result, a fixed axial positioning and a high degree of torsional rigidity is achieved.
