Built for durability: Made from strength steel with hardness and good toughness to resist wear and handle the torque demands of frequent workshop use. Designed to last through repeated tightening and maintenance cycles. Fast, reliable collet access: The compact Oshaped design provides quick, secure access to collet nuts—even in tight spaces—so you can change tooling faster and reduce downtime during setup or production runs. Improves workflow and safety: Compact profile and positive contact reduce slipping and rounding of collet nuts, helping maintain tool accuracy and lowering the risk of damage to spindles or workpieces. visibility color options: Available in red or black finishes to make the wrench easy to find on a crowded bench and help prevent misplacement among other tools. Broad compatibility: Intended for use with collet nuts and spindles on CNC machines, milling machines, and drill presses. (One compact spanner per ; ready to use out of the package.) Typical use scenarios CNC job changeover: Quickly loosen and tighten collet nuts when swapping end mills, routers, or tooling to shorten setup time between jobs. Machine maintenance: Routine tightening and inspection of collet nuts on milling and drilling spindles to keep tooling secure and maintain machining accuracy. Onthebench or field service: Portable, durable wrench for setup and tasks where space is limited and reliable access to collet nuts is required. What's included 1 CNC spanner (Oshaped), available in red or black finish, ready for immediate use.
