Omega Products Dual Contact DCBT30 Through Coolant Face Mill Arbor is a precision mounting shaft designed for face milling cutters used in CNC and manual milling setups. It enables through coolant delivery and secure, accurate tool mounting for demanding milling operations.

Engineered to perform at high speeds, this arbor is balanced to G2.5 at 25,000 RPM, delivering stability and a flatter finish even under heavy cutting loads. Its compact form, 27mm spigot size, and 40mm gauge length make it compatible with a wide range of standard face mills and setups.

• Balanced for high-speed milling: G2.5 balance at 25,000 RPM minimizes vibration, supporting smoother cuts, better surface finish, and longer cutter life during fast milling cycles.
• Through-coolant delivery: Through coolant channels feed coolant directly to the cutting edge, improving heat management, chip evacuation, and process stability in deep-pocket or flood-cooled applications.
• Secure mounting with precise fit: Dual-contact interface provides repeatable, rigid seating for reduced runout, while the 27mm spigot size and 40mm gauge length ensure broad compatibility and stable performance across standard face mills.

Using the DCBT30 Through Coolant Face Mill Arbor translates to faster cycle times, cleaner finishes, and fewer tool changes. The balanced, through-coolant design helps control heat and wear, while the secure mounting delivers reliable, repeatable results across jobs—boosting productivity without compromising accuracy.
