TAC Rockford Tool Holder Blank (HSK-A63)
The TAC Rockford 619.563.080.160 is a premium tool holder blank designed for custom machining and specialized tooling applications. Built on the highly rigid HSK-A63 taper standard, this blank allows shops to create custom-tailored tool holders that meet specific geometric or application requirements that standard off-the-shelf holders cannot fulfill.
The HSK-A (Hollow Shank Taper) design is the industry standard for high-speed machining, providing exceptional radial and axial repeatability and high clamping forces.
Key Performance Features
Customizable Design: The “Blank” part type features a large un-machined head (D=80mm, L=160mm), providing ample material for milling, boring, or shaping into custom tool configurations.
HSK-A63 Rigidity: Engineered for modern CNC machining centers, the HSK-A63 interface ensures maximum contact between the spindle and the tool holder for superior accuracy and surface finish.
Global Standard Compliance: Manufactured to meet ISO 12164-1, DIN 69893, and ASME B5.62 standards, ensuring perfect compatibility with your existing HSK-A63 spindle.
High-Strength Material: TAC Rockford blanks are typically made from high-quality steel, heat-treated on the taper end while leaving the head machinable for your specific tooling needs.
