HSKA-ER High-Speed Collet Tool Holder

The HSKA-ER places a widely used ER collet system on a short, lightweight HSK-A interface. Its selection angle is versatility: one holder family can cover drilling, reaming, tapping and milling while retaining the axial and radial repeatability required at higher spindle speeds.

Dynamic balancing grade: ≤G1.

High precision: Tool holder run-out accuracy: ≤2μm.

Combined run-out accuracy: ≤5μm.

BT-ER General-Purpose ER Tool Holder

BT-ER General-Purpose ER Tool Holder

The BT-ER is the broad-coverage option for common machining-center work. A 16-degree ER collet supports 1-30 mm h7 tools and quick tool changes across drilling, reaming, tapping, milling and engraving, with center-through coolant available through a suitable pull stud.

BT-SK High-Torque Collet Tool Holder

BT-SK High-Torque Collet Tool Holder

The BT-SK suits milling and drilling operations where torque transfer is more important than maximum clamping range. Its SK collet provides 1.5-times greater torque than other listed collet types, accepts 1-25 mm h7 tools and supports internal coolant.

BT-KR High-Precision KR Tool Holder

BT-KR High-Precision KR Tool Holder

The BT-KR is intended for users who prioritize collet precision retention and service life. KR collets use wear-resistant materials and controlled deformation, while PP-grade versions can reach radial runout within 1 μm for demanding high-speed machining.

BBT-ER Flexible ER Collet Tool Holder

BBT-ER Flexible ER Collet Tool Holder

The BBT-ER is the flexible clamping choice in the BBT group. Its ER collets accommodate a broad 1-30 mm h7 tool range for milling, drilling, tapping and engraving, while center-through coolant can be added through a compatible pull stud.

BBT-SK High-Torque Tool Holder

BBT-SK High-Torque Tool Holder

The BBT-SK is written for users selecting a torque-focused collet system on a BBT holder. The SK configuration increases clamping force for milling and drilling, supports h7 tools and can be arranged for internal coolant, separating it from the broader-range BBT-ER option.

ISO-KR Precision KR Collet Tool Holder

ISO-KR Precision KR Collet Tool Holder

The ISO-KR page should focus on precision retention rather than general tool-holder coverage. Its KR collet system is designed around clamping stability, low deformation and wear resistance, making it suitable for repeated high-speed boring, milling and drilling work.

ISO-ER General-Purpose Collet Tool Holder

ISO-ER General-Purpose Collet Tool Holder

The ISO-ER is positioned as the versatile option within the ISO interface family. Its ER collet format supports a broad tool-diameter range and quick tool changes across drilling, reaming, tapping and milling, rather than prioritizing maximum torque or ultra-low collet deformation.

ISO-SK High-Torque Collet Tool Holder

ISO-SK High-Torque Collet Tool Holder

The ISO-SK is the torque-oriented member of the ISO group. Its 8-degree SK collet geometry increases holding strength for heavier milling and drilling, while the stated 1-25 mm h7 tool range gives the page a different selection purpose from ISO-ER and ISO-KR.
