Introducing the Omega Dual Contact DCBT30 End Mill Holder — a precision tool holder designed for CNC milling where tool stability and accuracy matter most. Built to securely mount straight-shank end mills with Weldon flats, it delivers repeatable performance in demanding production environments. With a 20 mm bore size and a 70 mm gauge length, it offers compact yet rigid support for pocketing, profiling, and finishing tasks.

Engineered to Form AD standards and balanced to G2.5 at 25,000 RPM, the DCBT30 delivers smooth, high-speed performance with reduced vibration. Its dual-contact design — combining face and taper contact — ensures consistent tool seating and minimal runout, helping you achieve tight tolerances and superior finish quality even at premium speeds.

• Face and taper contact for maximum rigidity: Delivers rock-solid stability, reducing runout and chatter for precise finishes at high speeds.
• G2.5 balance at 25,000 RPM: Enables smoother operation with less vibration, allowing faster feeds, better surface finish, and longer tool life.
• 20 mm bore, 70 mm gauge length with Weldon-flat ER compatibility: Provides secure clamping of straight-shank tools with Weldon flats and reliable seating across demanding milling applications.

This end mill holder helps your workflow stay consistent and productive by combining rigid clamping, high-speed stability, and compatible geometry. Expect improved dimensional accuracy, reduced downtime from tool chatter, and repeatable results across batches and materials — making the DCBT30 a trustworthy choice for job shops, engineering teams, and serious hobbyists alike.
