Omega Products Dual Contact DCBT40 End Mill Holder - G2.5 - 25,000RPM - 20mm Bore Size - 63mm Gauge Length

The Omega DCBT40 Dual-Contact End Mill Holder is engineered to securely grip straight-shank end mills with Weldon flats, delivering dependable tool retention and precise alignment for CNC milling. With a 20 mm bore and a 63 mm gauge length, it fits common tooling and provides a stable, predictable reach for a wide range of operations.

A dual-contact design combines face and taper engagement to deliver maximum rigidity at high speeds. This holder is engineered to Form AD standards and balanced to G2.5 at 25,000 RPM, ensuring smooth, high-speed performance even under demanding milling conditions.

• Dual-contact rigidity: Face and taper engagement minimize deflection and chatter, delivering cleaner finishes and greater tool stability during heavy cuts.
• Weldon-flat ER tool mounting: Secure, repeatable clamping for straight-shank tools reduces runout and ensures consistent alignment with every tool change.
• High-speed balance and precision: Form AD compliant and balanced to G2.5 at 25,000 RPM for reliable, smooth operation at top speeds.

This end mill holder supports faster, more confident milling by providing rigid, repeatable performance, predictable setup, and durability under demanding CNC tasks. With a 20 mm bore and 63 mm gauge length, it maintains compatibility with standard tooling while delivering consistent results across production and prototyping environments.
