Description
Omega's HSK63A End Mill Holder is built for high-precision, high-speed milling. It delivers a secure, repeatable connection between spindle and tool, helping you push faster cuts with reduced runout and longer tool life.
Designed to perform under demanding conditions, it supports speeds up to 20,000 RPM thanks to a precision-balanced G6.3 specification and a robust HSK63A taper. The 25mm bore accepts common tool shanks, while a gauge length of 160mm provides stable support for deep pocketing and long-reach operations.
- HSK63A Taper for Secure, Low-Runout Interface: Ensures a precise, repeatable fit between holder and spindle, minimizing runout for better tool life and finish.
- G6.3 Balancing Up to 20,000 RPM: Engineered to minimize vibration at high speeds, enabling faster feeds, cleaner finishes, and extended tool life.
- Versatile 25mm Bore with 160mm Gauge Length: Fits a wide range of end mills and provides stable support with a long reach for deep cuts, reducing changeovers and downtime.
This end mill holder helps you maintain precision across various projects, improving process stability and delivering consistent results. The secure taper, balanced design, and generous gauge length translate into longer tool life, fewer rework passes, and smoother operation on demanding CNC setups.
