HSK 63F High-Speed Tool Holders for CNC Routers and Machining Centers
HSK 63F high-speed tool holders are built for performance on precision CNC routers, machining centers, and point-to-point machines with automatic tool changers. Designed to meet the demands of modern manufacturing, the HSK (Hollow Shank Taper) system originated in Germany as a standardized solution for high-speed, high-accuracy machining.
While HSK machine interface styles range from Type A through F—primarily differing in taper size—the HSK 63F has become the most popular choice in woodworking and composite applications due to its balance of speed, precision, and compatibility.
Why Choose Our HSK 63F Tool Holders?
Unlike generic options, our tool holders deliver exceptional quality and performance:
- They’re precision-balanced to G2.5 specifications (per DIN 69893), ensuring smooth operation even at high RPMs.
- We use high-grade, anti-rust treated steel, then case harden it to 58±2 HRC for durability.
- With a runout tolerance under 0.003 mm, you get consistent, reliable performance.
- The symmetrical design enhances rotational stability and reduces vibration during cutting.
As a result, you’ll experience improved surface finish, longer tool life, and higher overall productivity.
Flexible Collet System Compatibility
To accommodate various tooling needs, these holders are offered in several collet systems:
- ER32 collets support tool shanks up to 20mm diameter
- ER40 and RDO 35 (SYOZ25) collets hold tools up to 1″ in diameter
Generally, ER collets are used on Italian CNC machines such as SCM (Routech, Morbidelli), Biesse, and Busellato. On the other hand, RDO collets, known for their tighter range tolerances, are favored on German machines like Weeke, Homag, and Holz-Her, as well as North American brand, Onsrud.
Designed for Interchangeability
One of the key advantages of the HSK system is its machine-to-machine compatibility. For example, if you’re running an SCM Routech and need to use a tool with a 25mm shank—but your existing holders can’t handle that size—you don’t need a machine upgrade. Simply switch to an HSK 63F holder that supports RDO or ER40 collets, and you’re ready to go.
Optimize Performance with the Right Accessories
To maximize precision and minimize tool slippage or chatter, we recommend using ball bearing collet nuts. This small upgrade can significantly enhance machining quality and consistency, especially during high-speed operations.
