The Omega Products Dual Contact DCBT40 End Mill Holder is built for precision-heavy CNC milling. It uses dual contact on the face and taper to maximize rigidity, delivering stable tool engagement and reduced runout at high speeds.

Designed for straight shank end mills with Weldon flats, this holder features a 40 mm bore and a 105 mm gauge length, offering versatile mounting options while maintaining balance and reliability up to 25,000 RPM. It is engineered to Form AD standards and balanced to G2.5 for smooth, consistent performance.

• Dual-contact rigidity (face and taper): Maximizes tool stability by engaging both the face and the taper, reducing runout and chatter for cleaner cuts at high speeds.
• 40 mm bore, 105 mm gauge length, and Weldon-flat straight shank mounting: Secure seating for straight shank end mills with Weldon flats, enabling reliable clamping, quick setup, and repeatable results even under heavy cutting loads.
• Form AD compliant and G2.5-balanced to 25,000 RPM: Engineered to Form AD standards and precision-balanced to G2.5, delivering smooth operation and long tool life at up to 25,000 RPM.

With this end mill holder, you gain increased rigidity, improved surface finish, longer tool life, and reduced downtime due to tool seating issues. The combination of dual-contact design, compatible bore and gauge length, and precise balance at 25,000 RPM translates into more consistent results, less chatter, and greater overall productivity in CNC milling tasks.
