The Omega Dual Contact DCBT40 End Mill Holder is a precision toolholding solution engineered for CNC machining. Designed for engineers, machinists, and shops that demand stable, repeatable milling of straight‑shank end mills, it features a 16 mm bore and a 63 mm gauge length to deliver a compact yet rigid interface that handles high speeds up to 25,000 RPM.

With Weldon-flat ER compatibility and engineering that meets Form AD standards, this holder uses both face and taper contact to maximize rigidity. Balanced to G2.5 at 25,000 RPM, it delivers smooth, high‑speed performance for demanding applications where reliability and accuracy matter.

• Dual-Contact Rigidity for Superior Tool Stability: Face and taper contact lock the tool firmly in place, reducing runout and chatter for consistent results across passes.
• High-Speed Balance for 25,000 RPM: G2.5 balance at high speed and Form AD compliant design minimize vibration, supporting precision cuts and better surface finish.
• Weldon-Flat Mounting for 16 mm Tools: Clamps straight‑shank end mills with Weldon flats securely, with a predictable 63 mm gauge length for repeatable tooling setup.

This holder translates into tangible workflow benefits: reliable tool seating under heavy loads, reduced rework from runout, and faster tool changes for improved uptime. The combination of dual-contact rigidity, precise high‑speed balance, and Weldon-flat compatibility helps you achieve stable, accurate milling outcomes across a wide range of CNC applications.
