- The WorkBee Router Head is a high-performance router head, designed for precision and reliability in light to medium-duty CNC machining applications. With a 710W motor and ER11 collet system, it excels at detailed milling, engraving, and cutting tasks on materials such as wood, plastics, and soft metals like aluminium. Designed to integrate seamlessly with the WorkBee CNC Machine, this router head is a trusted choice among CNC users seeking consistent performance and everyday dependability. Its variable speed range of 13,000 to 33,000 RPM, combined with constant speed control, ensures consistent results across a variety of materials, even under load. The integrated soft start provides smooth, controlled operation right from startup. Compact and capable, the WorkBee Router Head is ideal for CNC users who value efficiency, accuracy, and ease of use. Pros and Cons Designed specifically for CNC use, the WorkBee Router Head combines performance and versatility, with the added precision of an ER11 collet system. Pros Cons Balanced Value: Offers pro-grade features at a mid-range price point. Wide Speed Range: 13,000–33,000 RPM supports a variety of materials and tooling sizes. Soft Start: Enables smoother startup and greater control. Constant Speed Control: Maintains consistent RPM under load. ER11 Collet System: Allows for a wide range of endmill sizes with superior clamping force. Lower Power: 710W may struggle with more aggressive cuts or harder materials. ER Collet System The ER collet system is the most widely adopted and versatile collet standard in machining. Its tapered design and alternating slots provide strong, even clamping force along the entire length of the collet, ensuring a secure grip on cutting tools. In addition to improved tool holding, the ER system offers a built-in clamping range of -0.5mm per collet, reducing the need for a large inventory of specific sizes. The WorkBee Router Head uses the ER11 size of the ER collet system. This allows you to use router bits ranging from 0.5mm to 7mm in diameter. Thanks to the clamping flexibility, a full set of ER11 collets in 1mm increments enables compatibility with virtually every diameter tool within that range, offering unmatched flexibility for a wide range of CNC operations.
