Capacity and fit Oversized quickchange lathe tool holder designed to accept a 5/8' tool bit for larger cutting edges and extended service life. Fits standard #1 holders so it integrates with common quickchange toolpost systems. Interchangeable compatibility Directly compatible with Dorian, Aloris, and Phase II Series tool holders for easy retrofitting into existing setups. Allows seamless tool holder swaps without modifying your machine or fixtures. Timesaving functionality Locks turning and facing tools together to minimize tool changeover time and reduce operator effort during multistep operations. Simplifies setups where alternating between turning and facing is frequent, improving workflow continuity. Who this helps and why it matters Shops that run mixed manual and CNC turning operations and need faster, repeatable changeovers. Operators who require consistent tool positioning when switching between turning and facing applications. Production environments where reducing downtime and maintaining throughput are priorities. Key attributes Function: quickchange lathe tool holder for 5/8' bits; supports locking of paired tools. Compatibility: standard #1 holders; interchangeable with Dorian, Aloris, Phase II Series. Performance: reduces changeover time and supports efficient machining sequences in professional environments. Intended use: CNC machine tool accessory suitable for lathe toolposts and quickchange systems. Typical applications 1. Production lathe runs alternating roughing and finishing operations — swap from a heavy turning bit to a facing tool quickly while keeping setup alignment. 2. Shortrun parts or prototype turning where rapid tool changes and repeatable positioning cut setup time between passes. 3. CNC accessory upgrade for shops that want to standardize holders across manual and CNC lathes using Dorian, Aloris, or Phase II tooling. This oversized quickchange holder improves efficiency and compatibility without changing your existing #1 quickchange infrastructure, and it helps reduce tool change time by locking turning and facing tools together for smoother, faster operations.
