Synchronised Thread‑cutting Holder DIN 69893 A (HSK‑A63) – TECWERK, M3–M20, A = 98 mm

A Synchronised Thread‑cutting Holder DIN 69893 A (HSK‑A63) intended for CNC machines with synchronised thread‑cutting units, compatible with thread sizes M3–M20 and designed to compensate pitch and spindle differences.

• HSK‑A63 mount for high‑speed spindles
• Compensates synchronisation errors ±0.5 mm
• Integrated coolant supply for tool life
• Suitable for right‑ and left‑hand threads

Faster, predictable thread cycles through precise compensation

The synchronised holder is engineered to tackle the common mismatch between tap pitch and spindle feed by providing synchronisation error compensation. Because axial variation is absorbed by the built‑in mechanism (axial compensation ±0.5 mm), cycle interruptions and broken taps are significantly reduced; this translates into fewer tool changes and less unplanned downtime. The HSK‑A63 interface ensures a rigid connection to modern spindle systems while maintaining the quick change benefits expected on production lines. By stabilising the thread‑cutting process, the system promotes consistent thread geometry across batches and lowers the risk of scrap.

Increased tool life and process reliability with coolant and clamping design

This tool holder features an integrated coolant supply that delivers cutting fluid directly to the engagement zone, improving chip evacuation and reducing thermal load on the cutting edges. The design also provides high clamping force, achieved via tensioning in tap‑collets with an integrated square drive, which secures taps firmly during both cutting and reversal operations. These functional elements extend the lifespan of coated taps and reduce wear rates, while the construction adheres to DIN 69893 A, ensuring compatibility with standard hollow shank tap holders. The result is a measurable improvement in throughput and a reduction in maintenance intervals.

Seamless integration on CNC machines and flexible thread capability

Designed for use on CNC machines equipped with a synchronised thread‑cutting unit, the holder copes with both right‑ and left‑hand threads and a broad size range from M3–M20, making it versatile for job shops and production cells alike. The ability to balance feed and spindle differences without manual intervention simplifies setup and shortens changeover times. High run‑out accuracy preserves thread concentricity and surface finish, which is particularly important when supplying components that must meet tight assembly tolerances. Where process certainty is required, this synchronised thread‑cutting holder provides a pragmatic, engineering‑led solution.

FAQ

What thread sizes are supported by this holder?
The synchronised thread‑cutting holder supports a thread range of M3–M20, which covers a wide variety of common metric threads used in precision production.

Can the holder be used for left‑hand threads?
Yes, the holder is suitable for both right‑ and left‑hand threads; the compensation mechanism functions irrespective of thread direction.

How much axial compensation does the device provide?
Axial compensation is specified as ±0.5 mm, allowing the holder to absorb small mismatches between tool pitch and spindle feed.

Is coolant delivery integrated into the tool?
An integrated coolant supply is provided, enabling direct lubrication and improved chip removal at the cutting interface.

Which spindle interface is required for installation?
The holder uses an HSK‑A63 mount and complies with DIN 69893 A, so it is compatible with spindles and tap holders built to the same standard.
